Cranberries! 11/22/2010
Health Benefits While familiar nutrients like vitamin C and fiber play a very important role in cranberry's health benefits, it's the amazing array of phytonutrients in cranberries that has gotten the special attention of health researchers. There are at least 5 key categories of health-supportive phytonutrients in cranberries, as summarized in the following chart: Cranberry Phytonutrients Type of PhytonutrientSpecific Molecules Phenolic Acidshydroxybenzoic acids including vanillic acids; hydroxycinnamic acids inculding caffeic, coumaric, cinnamic, and ferulic acids Proanthocyanidinsepicatechins Anthocyaninscyanidins, malvidins, and peonidins Flavonoidsquercetin, myricetin, kaempferol Triterpenoidsursolic acid The vast majority of phytonutrients presented in this chart have been studied for their antioxidant, anti-inflammatory, and anti-cancer properties, and in many cases the results have been impressive. Equally important in the cranberry research has been the finding that isolated phytonutrients in cranberry do not account for the same degree of health benefit as phytonutrients taken as a complete, synergistic group. What this research finding means is simple: it's the whole cranberry that supports our health best. When speaking in general terms about the health benefits of cranberries, it is also important to know that the most commonly consumed form of this food is juice processed from the berries and typically produced by adding generous amounts of sugar. This form of cranberry cannot provide you with cranberry's full phytonutrient benefits. The cranberry "presscake"-or what is left behind in terms of skins and flesh after the juice has been processed out-typically contains the bulk of the phytonutrients when evaluated in lab studies. Protection against Urinary Tract Infection (UTI) Long before researchers started investigating from the standpoint of science, cranberry has been used to help prevent and treat urinary tract infections (UTIs). While the acidity of cranberries was at one time an important target of research, we now know that cranberry's ability to provide UTI benefits is not primarily related to its acidity, but rather to its proanthocyanidin (PAC) content. The PACs in cranberry have a special structure (called A-type linkages) that makes it more difficult for certain types of bacteria to latch on to our urinary tract linings. Include in these types of bacteria are pathogenic (infection-causing) strains of E. coli - one of the most common microorganisms involved in UTIs. By making it more difficult for unwanted bacteria like E. coli to cling onto the urinary tract linings, cranberry's PACs help prevent the expansion of bacterial populations that can result in outright infection. The age group in which researchers are least sure about this process involves children-it's just not clear when cranberry's health benefits fully extend to this age group. The area where benefits have been most pronounced are in middle-aged women who have experienced recurrent UTIs. In some studies, UTIs in this age and gender group have been reduced by more than one- third through dietary consumption of cranberry. The discovery that cranberries prevent UTIs by blocking adhesion of bacteria to the urinary tract lining is a discovery that has allowed research on cranberry to expand out in other important directions. In our Digestive Benefits section below, we will describe how prevention of stomach ulcer is one very intriguing new direction in the cranberry research, based on this exact same principle of blocking bacterial adhesion to the lining of an organ system. (In the case of stomach ulcer, it's the stomach lining that's at risk, and the bacteria involved are the Helicobacter pylori bacteria.) Anti-Inflammatory Benefits For the cardiovascular system and for many parts of the digestive tract (including the mouth and gums, stomach, and colon) cranberry has been shown to provide important anti-inflammatory benefits. It's the phytonutrients in cranberry that are especially effective in lowering our risk of unwanted inflammation, and virtually all of the phytonutrient categories represented in cranberry are now known to play a role. These phytonutrient categories include proanthocyanidins (PACs), anthocyanins (the flavonoid pigments that give cranberries their amazing shades of red), flavonols like quercetin, and phenolic acid (like hydroxycinnamic acids). In the case of our gums, the anti-inflammatory properties of cranberry can help us lower our risk of periodontal disease. Chronic, excessive levels of inflammation around our gums can damage the tissues that support our teeth. It's exactly this kind of inflammation that gets triggered by ongoing overproduction of certain cytokines. (Cytokines are messaging molecules, and the pro-inflammatory cytokines tell our cells to mount an inflammatory response. As messages are sent more frequently and more constantly, the inflammatory response becomes greater.) Phytonutrients in cranberry help reduce this inflammatory cascade of events precisely at the cytokine level. Production of pro-inflammatory cytokines like interleukin 6 (IL-6) and RANTES (Regulated on Activation Normal T-cell Expressed and Secreted) is lowered by the activity of cranberry phytonutrients. In addition, cranberry phytonutrients inhibit the activity of the enzymes cyclo-oxygenase 1 (COX-1) and cyclo-oxygenase 2 (COX-2). These COX-1 and COX-2 enzymes are key factors in the production of other pro-inflammatory messaging molecules, and by inhibiting these enzymes, cranberry's phytonutrients significantly lower our risk of unwanted inflammation. Dietary consumption of cranberry has also been shown to reduce the Rrisk of chronic, unwanted inflammation in the stomach, large intestine (colon) and cardiovascular system (especially blood vessel linings). We'll discuss some of these health benefits in more detail in the Digestive Benefits and Cardiovascular Benefits sections of this cranberry profile. Mixed Findings for Kidney Stone Formation Contrary to popular opinion, we believe that the latest research shows mixed results for cranberry with respect to kidney stone formation. This area of the health research can be confusing. Kidney stones can be formed from several different mineral-including combinations. The most common type of kidney stones formed in the United States involves a combination of calcium-plus-oxalic acid and are called calcium-oxalate stones. Among U.S. adults who develop kidney stones, about 75% develop calcium-oxalate stones. The other 25% develop a variety of different stones, including calcium-phosphate stones (called brushite stones), magnesium-sulfate containing stones (called struvite stones), and uric acid-containing stones (called urate stones). Since cranberries have the ability to increase the concentration of both calcium and oxalate in the urine, they can increase the likelihood of calcium-oxalate stone formation in susceptible individuals. Urinary uric acid, however, is typically decreased by intake of cranberry, and so risk of urate stones in susceptible individuals can be decreased by intake of cranberry. With other types of kidney stones, mixed effects of cranberry intake have been demonstrated. From our perspective, the bottom line at this point in the research process seems clear: individuals with kidney stone problems of any kind, or known susceptibility to kidney stone formation, should talk with their healthcare provider if considering inclusion of cranberry in their diet. Since 3 out of 4 U.S. adults experiencing kidney stone problems develop calcium-oxalate stones, there's a good chance for cranberry to be a problematic addition to the diet in the case of U.S. adults with a history of kidney stone formation. Immune Support While research in this area is somewhat limited, recent studies on the immune support benefits of cranberry are exciting. In studies on very small numbers of human participants, intake of cranberry extracts has shown the ability to improve multiple aspects of immune function, and to lower the frequency of cold and flu symptoms in the subjects. In several of these studies, the cranberry extracts were standardized to contain a known, higher-end amount of proanthocyanidins (PACs)-somewhat comparable to a double-strength cranberry juice. From our perspective, the doses of cranberry extract used in these studies match up fairly well with generous intake of whole, raw cranberries, and we look forward to future studies focused on precisely that: intake of whole, raw cranberries and resulting changes in cold and flu symptoms. Cardiovascular Benefits Following decreased risk of urinary tract infection (UTI), increased health of the cardiovascular system is perhaps the best-researched area of cranberry health benefits. It's the combined impact of cranberry antioxidants and anti-inflammatory phytonutrients in cranberry that's responsible here. Oxidative stress and chronic inflammation can place our blood vessel walls at great risk of damage. Once damaged, our blood vessels walls can undergo a process of plaque formation, and our risk of atherosclerosis (blood vessel wall thickening and blood vessel blocking) can be greatly increased. Dietary intake of cranberries and cranberry juice (in normal everyday amounts, unchanged for research study purposes) has been shown to prevent the triggering of two enyzmes that are pivotal in the atherosclerosis process (inducible nitric oxide synthase, or iNOS, and cyclo-oxygenase 2, or COX-2). In both cases, cranberry has also been shown to prevent activation of these enzymes by blocking activity of a pro-inflammatory cytokine- messaging molecule called tumor necrosis factor alpha (TNF-alpha). These anti-inflammatory benefits of cranberry appear to be critical components in the cardiovascular protection offered by this amazing fruit. The antioxidant components of cranberries also appear to play a key role in cranberry's cardiovascular benefits. In animal studies, these antioxidant benefits have been clearly associated with decreased risk of high blood pressure. By reducing oxidative stress inside the blood vessels, cranberry extracts consumed by rats and mice have helped prevent overconstriction of the blood vessels and unwanted increases in blood pressure. Three related phytonutrient compounds- resveratrol, piceatannol, and pterostilbene-deserve special mention with respect to cranberry's antioxidants. These unique phytonutrients may provide cranberry with some equally unique antioxidant properties, and a special ability to support our cardiovascular system in this regard. A final area of cardiovascular support provided by cranberry is its ability to help us lower our LDL-cholesterol and total cholesterol, while simultaneously helping us increase our level of HDL-cholesterol. Cranberry most likely helps us achieve these cholesterol-improving changes by helping to improve oxidative and inflammatory aspects of the everyday environment in which our cholesterol-containing molecules must exist. This improved cholesterol control offered by cranberry contributes even further to our decreased risk of blood vessel blocking problems, since excess accumulation of LDL-cholesterol and insufficient amounts of HDL-cholesterol can increase the tendency of our blood vessels to become blocked. All in all, it's quite amazing how a simple food like cranberry can provide us with cardiovascular benefits at so many different levels, all rolled into one. Antioxidant Protection Although previously mentioned in this Health Benefits section, the antioxidants found in cranberry are especially important contributors to its potential for health support. From a research perspective, there are two especially important points to consider when thinking about the antioxidant benefits of cranberries. First is the amazing array of antioxidants that are found exclusively in whole cranberries. Cranberry's special combination of phenolic antioxidants, proanthocyanidin antioxidants, anthocyanin antioxidants, flavonoid antioxidants, and triterpenoid antioxidants is without a doubt unique. Also unique is the particular combination of three antioxidant nutrients-resveratrol, piceatannol, and pterostilbene-found in cranberry. Second are the research findings regarding the synergy between these nutrients. The phytonutrients in cranberry provide maximal antioxidant benefits only when consumed in combination with each other, and also only when consumed alongside of conventional antioxidant nutrients present in cranberry like manganese and vitamin C. When cranberry processing disrupts this antioxidant combination, health benefits from cranberry are decreased. Multiple studies in multiple health benefit areas point to this same conclusion-it's the overall blend of cranberry antioxidants that provides us with the strongest health benefits. One further point about cranberry antioxidant research seems worthy of mention. In several research studies, cranberries were unable to provide significant antioxidant benefits when those benefits were measured in terms of blood values. In these studies, it took a much closer look at activities going on inside of our cells to demonstrate the antioxidant benefits of cranberries. The need to look inside of our cells to find cranberry antioxidant benefits may be telling us that the special value of cranberries may often involve metabolic events that are taking place "behind the scenes." In other words, these benefits may sometimes be missed in more broadly focused research studies, and cranberry may in fact have a stronger research track record than previously assumed. Anti-Cancer Benefits No area of cranberry research has been more intriguing in the past 10 years than research on cranberry and cancer, even though the majority of studies in this area have involved lab studies on human cancer cells or animal experiments. On a virtual year-by-year basis, scientists continue to identify new mechanisms that establish cranberries as anti-cancer agents. These mechanisms are now known to include: blocked expression of MMPs (matrix metalloproteinases); inhibition of ODC (ornithine decarboxylase enzymes); stimulation of QRs (quinone reductase enzymes); inhibition of CYP2C9s (Phase I detoxification enzymes); and triggering of apoptosis (programmed cell death) in tumor cells. It's important to point out that this amazing list of anti-cancer properties in cranberry is not sufficient to establish cranberry as a food to be used in the treatment of cancer. However, it is a list that appears consistent with other studies of cranberry and cancer showing dietary intake of this food to help prevent cancer occurrence. These cancer-preventive benefits of cranberry are especially likely in the case of breast, colon, lung, and prostate cancer. None of the cancer-related benefits of cranberries should be surprising, since cranberry is loaded with antioxidant and anti-inflammatory nutrients. Chronic excessive oxidative stress (from lack of sufficient antioxidant support) and chronic excessive inflammation (from lack of sufficient anti-inflammatory compounds) are two key risk factors promoting increased likelihood of cancer. With its unique array of antioxidant and anti-inflammatory nutrients, cranberry seems ideally positioned to help us lower our risk of cancer development. Digestive Tract Benefits When you add up the health-related benefits of cranberry for our mouth and gums (decreased risk of periodontal disease), stomach (decreased risk of stomach ulcer), and colon (decreased risk of colon cancer), it's impossible not to conclude that cranberry is unique among fruits in its ability to provide us with digestive tract benefits. Every category of phytonutrient known to be provided by cranberry is also known to play a role in digestive tract support. In the case of cranberry's proanthocyanidins, it's decreased adherence of the bacterium Helicobacter pylori to our stomach wall that's made possible by intake of cranberry. In the case of cranberry's flavonoids, anthocyanins and triterpenoids, provide antioxidant and anti-inflammatory benefits that decrease our risk of colon cancer, and also our risk of periodontal disease. Recent research has also shown that cranberry may be able to help optimize the balance of bacteria in our digestive tract. Participants in one recent study involving cranberry juice intake (in amounts of approximately 2 ounces per day and over the course of about 3 months) were able to increase the numbers of Bifidobacteria in their digestive tract while maintaining other bacterial types (Bifidobacteria are typically considered to be a desirable and "friendly" type of bacteria). As a result, the relative amount of Bifidobacteria was increased, and the bacterial environment of the digestive tract may have become more favorable. Given the vast array of phytonutrients in cranberry and the known connection between so many of these phytonutrients and digestive tract health, we expect to see the digestive benefits of cranberry becoming more and more apparent in future research on this incredible berry. History American Indians enjoyed cranberries cooked and sweetened with honey or maple syrup-a cranberry sauce recipe that was likely a treat at early New England Thanksgiving feasts. By the beginning of the 18th century, the tart red berries were already being exported to England by the colonists. Cranberries were also used by the Indians decoratively, as a source of red dye, and medicinally, as a poultice for wounds since not only do their astringent tannins contract tissues and help stop bleeding, but we now also know that compounds in cranberries have antibiotic effects. Although several species of cranberries grow wild in Europe and Asia and have always been enjoyed in these part of the world, the cranberry most cultivated as a commercial crop is an American native, which owes its success to one Henry Hall, an observant gentleman in Dennis, Massachusetts. In 1840, Mr. Hall noticed an abundance of large berries grew when sand was swept into his bog by the prevailing winds and tides. The sandy bog provided just the right growing conditions for the cranberries by stifling the growth of shallow-rooted weeds, thus enhancing that of the deep rooted cranberries. Cranberry cultivation soon spread not only across the U.S. through Wisconsin to Washington and Oregon, but also across the sea to Scandinavia and Great Britain. The hardy berries arrived in Holland as survivors of a shipwreck. When an American ship loaded with crates filled with cranberries sank along the Dutch coast, many crates washed ashore on the small island of Terschelling; some of the berries took root, and cranberries have been cultivated there ever since. How to Select and Store A fruit with a short season, fresh cranberries are harvested between Labor Day and Halloween and appear in markets from October through December. Choose fresh, plump cranberries, deep red in color, and quite firm to the touch, lacking broken or mushy berries. Firmness is a primary indicator of quality. In fact, during harvesting, high quality cranberries are often sorted from lesser quality fruits by bouncing the berries against barriers made of slanted boards. The best berries bounce over the barriers, while the inferior ones collect in the reject pile. The deeper red their color, the more highly concentrated are cranberries' beneficial anthocyanin compounds. The Early Black cultivar (variety) of cranberry-with its particularly deep red color-has been found in one research study to have the highest concentration of anthocyanins. Although typically packed in 12-ounce plastic bags, fresh cranberries, especially if organic, may be available in pint containers. Fresh ripe cranberries can be stored in the refrigerator for up to 20 days. Before storing, discard any soft, discolored, pitted or shriveled fruits. When removed from the refrigerator, cranberries may look damp, but such moistness does not indicate spoilage, unless the berries are discolored or feel sticky, leathery or tough. Once frozen, cranberries may be kept for several years. To freeze, spread fresh cranberries out on a cookie sheet and place in the freezer. In a couple of hours, the fully frozen berries will be ready to transfer to a freezer bag. Don't forget to date the bag before returning to the freezer. Once thawed, frozen berries will be quite soft and should be used immediately. Dried cranberries are sold in many groceries and may be found with other dried fruits. How to Enjoy Tips for preparing cranberries While not as fragile as blueberries, fresh cranberries should be treated with care. Just prior to use, place cranberries in a strainer and briefly and gently rinse under cool running water. When using frozen berries in recipes that do not require cooking, thaw well and drain prior to using. For cooked recipes, use unthawed berries since this will ensure maximum flavor. Extend the cooking time a few minutes to accommodate for the frozen berries. A Healthiest Way of Preparing Cranberries Cranberries retain their maximum amount of nutrients and their maximum taste when they are enjoyed fresh and not prepared in a cooked recipe. That is because their nutrients—:including vitamins, antioxidants, and enzymes- are unable to withstand the temperature (350̊F/175̊C) used in baking. A few quick serving ideas
Individual Concerns Cranberries and Oxalates Cranberries are among a small number of foods that contain measurable amounts of oxalates, naturally -occurring substances found in plants, animals, and human beings. The relationship between cranberries and formation of kidney stones containing oxalates is not what you might expect, however. In the case of cranberries, the oxalate content is actually quite low, between 5-7 milligrams per 3.5 ounces. However despite their low oxalate content, cranberries are able to increase the amount of both oxalates and calcium in the urine, resulting in urine with increased concentrations of calcium oxalate. (The acidity of cranberries and other aspects of their chemical composition appear responsible for this impact on the urine.) Individuals at risk of calcium oxalate kidney stone formation will most likely want to avoid cranberries for the above reasons, and if considering inclusion of cranberries in their diet, should consult beforehand with a qualified healthcare provider. For some other, less common types of kidney stones - including struvite stones (containing magnesium sulfate) and brushite stones (one form of stones containing calcium phosphate), intake of cranberry juice may actually help lower a person's risk. As you can see, the relationship between cranberry juice and kidney stones can sometimes be confusing, and for this reason, if you are in doubt about this aspect of your health, we recommend a consult with your healthcare provider before making a decision about cranberries in your diet. Cranberries and Warfarin Warfarin is a prescription anticoagulant medication that has widely been used to help prevent formation of blood clots in individuals with a strong tendency toward clotting, and to help prevent future episodes in individuals who have already experienced formation of unwanted blood clots. Over the past ten years, there have been a small number of published case studies reporting cranberry juice-related problems by individuals taking warfarin. Despite the small number of cases, however, these reported problems have been quite serious, and in one circumstance, involved the death of an individual who was following his doctor's medical prescription for warfarin and while also consuming cranberry juice. The connection between cranberry juice and warfarin treatment has now been clearly shown to involve the detoxification enzyme family CYP2C9. The activity of this enzyme family is needed to break down warfarin so that its anticoagulant activity does not become excessive. (If CYP2C9 enzymes in the liver cannot successfully metabolize and neutralize warfarin, it can become too difficult for a person to stop an occurrence of bleeding.) Even though we now know that cranberry juice can inhibit CYP2C9 enzymes, researchers are still not clear about the risk posed by cranberries and cranberry juice for individuals who have been placed on a warfarin prescription. In lab studies, cranberry juice has repeatedly been shown to inhibit the breakdown of warfarin by CYP2C9 enzymes. However, in a recent study on health human volunteers who consumed three 8.5-ounce glasses of double-strength cranberry juice along with a single dose of warfarin, this inhibiting of CYP29C enzymes failed to occur. Overall, these research results seem somewhat confusing, and to err on the safe side, I encourage and recommend that all persons taking warfarin consult with their healthcare provider before incorporating cranberries or cranberry juice into the diet.

Olives, from the "Tree of life" Health Benefits Cellular Protection Against Free Radicals Protection From Heart Disease Support Gastrointestinal Health Beneficial Anti-Inflammatory Effects Olives are concentrated in monounsaturated fats and a good source of vitamin E. Because monounsaturated fats are less easily damaged than polyunsaturated fats, it's good to have some in our cells' outer membranes and other cell structures that contain fats, such as the membranes that surround the cell's DNA and each of its energy-producing mitochondria. The stability of monounsaturated fats translates into a protective effect on the cell that, especially when combined with the antioxidant protection offered by vitamin E, can lower the risk of damage and inflammation. In addition to vitamin E, olives contain a variety of beneficial active phytonutrient compounds including polyphenols and flavonoids, which also appear to have significant anti-inflammatory properties. More Recently a compound isolated from the leaves and fruit of the olive plant called Oleuropein has show remarkable anti-fungal, anti-bacterial, anti-cancer activity. Cellular Protection Against Free Radicals Vitamin E is the body's primary fat-soluble antioxidant. It goes after and directly neutralizes free radicals in all the fat-rich areas of the body. In combination, stable monounsaturated fats and vitamin E add a significant safety factor to cellular processes like energy production, a process that generates free radicals even when things are running smoothly. When cellular processes such as mitochondrial energy production are not well protected, the free radicals produced can interact with and damage any nearby molecules-a process called oxidation. When a cell's mitochondria become damaged, the cell cannot produce enough energy to supply its needs and dies. If a cell's DNA becomes damaged, the cell may mutate and become cancerous. Protection From Heart Disease Free radical damage can lead to numerous ailments. For example, when free radicals cause the oxidation of cholesterol, the oxidized cholesterol damages blood vessels and builds up in arteries, and can eventually lead to heart attack or stroke. So, by preventing the oxidation of cholesterol, the nutrients in olives help to prevent heart disease. Support Gastrointestinal Health If free radicals damage the cellular DNA in colon cells, the cells can mutate into cancer cells. By neutralizing free radicals, the nutrients in olives help prevent colon cancer. A higher intake of both vitamin E and the monounsaturated fats in olives is actually associated with lower rates of colon cancer. Beneficial Anti-Inflammatory Effects The anti-inflammatory actions of the monounsaturated fats, vitamin E and polyphenols in olives may also help reduce the severity of asthma, osteoarthritis, and rheumatoid arthritis, three conditions where most of the damage is caused by high levels of free radicals. The vitamin E in olives may even help to reduce the frequency and/or intensity of hot flashes in women going through menopause. Description Olives are fruits of the tree known as Olea europaea. "Olea" is the Latin word for "oil," reflecting the olives very high fat content, of which 75% is oleic acid, a monounsaturated fat that has been shown to lower blood cholesterol levels. "Europaea" reminds us that olives are native to the Mediterranean region of Europe. Olives cannot be eaten right off of the tree; they require special processing to reduce their intrinsic bitterness, caused by the glycoside oleuropein, which is concentrated in their skin. These processing methods vary with the olive variety, cultivation region, and the desired taste, texture and color to be created. Some olives are picked green and unripe, while others are allowed to fully ripen on the tree to a black color. Yet, not all of the black olives available begin with a black color. Some processing methods expose unripe greens olives to the air, and the subsequent oxidation turns them a dark color. In addition to the original color of the olive determining its finished characteristics, the color is affected by a variety of processing methods that olives undergo including fermentation and/or curing in oil, water, brine or salt. These methods may not only cause the olives to turn black, purple, brown, red, or yellow, but they also affect the skin texture, causing it to be smooth and shiny or wrinkled. Some of the many available delicious varieties of olives include Moroccan oil-cured, Kalamata, Nicoise, Picholine and Manzanilla. In addition to varying in size and appearance, the flavor of olives spans the range from sour to smoky to bitter to acidic. In addition to whole olives, you can often find them pitted. Olive oil is available in a variety of grades that reflects the degree to which it has been processed. Extra-virgin is the initial unrefined oil from the first pressing. Virgin olive oil is also derived from the first pressing but has a higher acidity level than extra virgin olive oil (as well as less phytonutrients and a less delicate taste). Chemically, the difference bewtween an extra virgin oil and a virgin oil involves the amount of free oleic acid, which is a marker for overall acidity. According to the standards adopted by the International Olive Oil Council, "virgin" can contain up to 2% free oleic acid, while "extra virgin" can contain up to 0.8% of free oleic acid. Pure olive oil usually means a lower-quality oil produced from subsequent pressings. History Olives, one of the oldest foods known, are thought to have originated in Crete between five and seven thousand years ago. Their use quickly spread throughout Egypt, Greece, Palestine and Asia Minor. Olives are mentioned in the Bible, depicted in ancient Egyptian art, and played an important role in Greek mythology. Since ancient times, the olive tree has provided food, fuel, timber and medicine for many civilizations. It has also been regarded as a symbol of peace and wisdom. Olive oil has been consumed since 3000 BC. Olives were brought to America by the Spanish and Portuguese explorers during the 15th and 16th century. Franciscan missinaries introduced olives into California in the late 18th century. Today, much of the commercial cultivation of olives occurs in Spain, Italy, Greece, and Turkey. How to Select and Store While olives have been traditionally sold in jars and cans, many stores are now offering them in bulk in large barrels. Buying bulk olives will allow you to experiment with many different types with which you may be unfamiliar and to purchase only as many as you need at one time. While whole olives are very common, you may also find ones that have been pitted, as well as olives that have been stuffed with either peppers, garlic or almonds. If you purchase olives in bulk, make sure that the store has a good turnover and keeps their olives immersed in brine for freshness and to retain moistness. Olives will keep freshest if stored in an airtight container in the refrigerator. Tips for Preparing Olives: To pit olives, press them with the flat side of a broad bladed knife. This will help break the flesh so that you can easily remove the pit with your fingers or the knife. The brine in which olives are packed can be used as a replacement for salted water in recipes. A Few Quick Serving Ideas: -Olive tapenade is a delicious and easy-to-make spread that you can use as a dip, sandwich spread, or topping for fish and poultry. To make it, put pitted olives in a food processor with olive oil, garlic, and your favorite seasonings. -puree it as a base for a sauce or salad dressing Toss pasta with chopped olives, tomatoes, garlic, olive oil and fresh herbs of your choice. -Marinate olives in olive oil, lemon zest, coriander seeds and cumin seeds. -Throw a small amount of olives when making your hummus for a rich flavor. -Add chopped olives to your favorite tuna or chicken salad recipe. -Set out a small plate of olives on the dinner table along with some vegetable crudités for your family to enjoy with the meal. Individual Concerns Olives are not a commonly allergenic food, are not known to contain measurable amounts of oxalates or purines and are also not included in the Environmental Working Group's 2009 report "Shopper's Guide to Pesticides" as one of the 12 foods most frequently containing pesticide residues. Health food of the Week: Potato 01/27/2010
Health Benefits -Potatoes' Phytochemicals Rival Those in Broccoli -Blood-Pressure Lowering Potential -Vitamin B6-Building Your Cells -Vitamin B6-Brain Cell and Nervous System Activity -Vitamin B6-Cardiovascular Protection -Vitamin B6-Athletic Performance Potatoes are a very popular food source. Unfortunately, most people eat potatoes in the form of greasy French fries or potato chips, and even baked potatoes are typically loaded down with fats such as butter, sour cream, melted cheese and bacon bits. Such treatment can make even baked potatoes a potential contributor to a heart attack. But take away the extra fat and deep frying, and a baked potato is an exceptionally healthful low calorie, high fiber food that offers significant protection against cardiovascular disease and cancer. potatoes are a very good source of vitamin C, a good source of vitamin B6, copper, potassium, manganese, and dietary fiber. Potatoes also contain a variety of phytonutrients that have antioxidant activity. Among these important health-promoting compounds are carotenoids, flavonoids, and caffeic acid, as well as unique tuber storage proteins, such as patatin, which exhibit activity against free radicals. Potatoes' Phytochemicals Rival Those in Broccoli Potatoes' reputation as a high-carb, white starch has removed them from the meals of many a weight-conscious eater, but this stereotype is due for a significant overhaul. A new analytical method developed by Agricultural Research Service plant geneticist Roy Navarre has identified 60 different kinds of phytochemicals and vitamins in the skins and flesh of 100 wild and commercially grown potatoes. Analysis of Red and Norkotah potatoes revealed that these spuds' phenolic content rivals that of broccoli, spinach and Brussels sprouts, and includes flavonoids with protective activity against cardiovascular disease, respiratory problems and certain cancers. Navarre's team also identified potatoes with high levels of vitamin C, folic acid, quercetin and kukoamines. These last compounds, which have blood pressure lowering potential, have only been found in one other plant, Lycium chinense (a.k.a., wolfberry/gogi berry). How much kukoamine is needed for a blood pressure lowering effect in humans must be assessed before it can be determined whether an average portion of potatoes delivers enough to impact cardiovascular health. Still, potatoes' phytochemical profiles show it's time to shed their starch-only image; spuds-baked, steamed or healthy sautéed but not fried-deserve a place in your healthy way of eating."Phytochemical Profilers Investigate Potato Benefits,"Agricultural Research, September 2007 Blood-Pressure Lowering Potential UK scientists at the Institute for Food Research have identified blood pressure-lowering compounds called kukoamines in potatoes. Previously only found in Lycium chinense, an exotic herbal plant whose bark is used to make an infusion in Chinese herbal medicine, kukoamines were found in potatoes using a new type of research called metabolomics. Until now, when analyzing a plant's composition, scientists had to know what they were seeking and could typically look for 30 or so known compounds. Now, metabolomic techniques enable researchers to find the unexpected by analyzing the 100s or even 1000s of small molecules produced by an organism. "Potatoes have been cultivated for thousands of years, and we thought traditional crops were pretty well understood," said IFR food scientist Dr Fred Mellon, "but this surprise finding shows that even the most familiar of foods might conceal a hoard of health-promoting chemicals." Another good reason to center your diet around the World's Healthiest Foods! In addition to potatoes, researchers looked at tomatoes since they belong to the same plant family-Solanaceae-as Lycium chinense. Metabolomic assays also detected kukoamine compounds in tomatoes. The IFR scientists found higher levels of kukoamines and related compounds than some of the other compounds in potatoes that have a long history of scientific investigation. However, because they were previously only noted in Lycium chinense, kukoamines have been little studied. Researchers are now determining their stability during cooking and dose response (how much of these compounds are needed to impact health). Vitamin B6-Building Your Cells If only for its high concentration of vitamin B6-a cup of baked potato contains 21.0% of the daily value for this important nutrient-the potato earns high marks as a health-promoting food. Vitamin B6 is involved in more than 100 enzymatic reactions. Enzymes are proteins that help chemical reactions take place, so vitamin B6 is active virtually everywhere in the body. Many of the building blocks of protein, amino acids, require B6 for their synthesis, as do the nucleic acids used in the creation of our DNA. Because amino and nucleic acids are such critical parts of new cell formation, vitamin B6 is essential for the formation of virtually all new cells in the body. Heme (the protein center of our red blood cells) and phospholipids (cell membrane components that enable messaging between cells) also depend on vitamin B6 for their creation. Vitamin B6-Brain Cell and Nervous System Activity Vitamin B6 plays numerous roles in our nervous system, many of which involve neurological (brain cell) activity. B6 is necessary for the creation of amines, a type of messaging molecule or neurotransmitter that the nervous system relies on to transmit messages from one nerve to the next. Some of the amine-derived neurotransmitters that require vitamin B6 for their production are serotonin, a lack of which is linked to depression; melatonin, the hormone needed for a good night's sleep; epinephrine and norepinephrine, hormones that help us respond to stress; and GABA, which is needed for normal brain function. Vitamin B6-Cardiovascular Protection Vitamin B6 plays another critically important role in methylation, a chemical process in which methyl groups are transferred from one molecule to another. Many essential chemical events in the body are made possible by methylation, for example, genes can be switched on and turned off in this way. This is particularly important in cancer prevention since one of the genes that can be switched on and off is the tumor suppressor gene, p53. Another way that methylation helps prevent cancer is by attaching methyl groups to toxic substances to make them less toxic and encourage their elimination from the body. Methylation is also important to cardiovascular health. Methylation changes a potentially dangerous molecule called homocysteine into other, benign substances. Since homocysteine can directly damage blood vessel walls greatly increasing the progression of atherosclerosis, high homocysteine levels are associated with a significantly increased risk for heart attack and stroke. Eating foods rich in vitamin B6 can help keep homocysteine levels low. In addition, diets high in vitamin B6-rich foods are associated with overall lower rates of heart disease, even when homocysteine levels are normal, most likely because of all the other beneficial activities of this energetic B vitamin. A single baked potato will also provide you with 11.7% of the daily value for fiber, but remember the fiber in potatoes is mostly in their skin. If you want the cholesterol-lowering, colon cancer preventing, and bowel supportive effects of fiber, be sure to eat the potato's flavorful skin as well as its creamy center. Vitamin B6-Athletic Performance Vitamin B6 is also necessary for the breakdown of glycogen, the form in which sugar is stored in our muscle cells and liver, so this vitamin is a key player in athletic performance and endurance. Description Whether it is mashed, baked or made into French fries, many people often think of the potato as a comfort food. This sentiment probably inspired the potato's scientific name, Solanum tuberosum, since solanum is derived from a Latin word meaning "soothing". The potato's name also reflects that it belongs to the Solanaceae family whose other members include tomatoes, eggplants, peppers, and tomatillos. There are about about 100 varieties of edible potatoes. They range in size, shape, color, starch content and flavor. They are often classified as either mature potatoes (the large potatoes that we are generally familiar with) and new potatoes (those that are harvested before maturity and are of a much smaller size). Some of the popular varieties of mature potatoes include the Russet Burbank, the White Rose and the Katahdin, while the Red LeSoda and Red Pontiac are two types of new potatoes. There are also delicate fingerling varieties available which, as their name suggests, are finger-shaped. The skin of potatoes is generally brown, red or yellow, and may be smooth or rough, while the flesh is yellow or white. There are also other varieties available that feature purple-grey skin and a beautiful deep violet flesh. As potatoes have a neutral starchy flavor, they serve as a good complement to many meals. Their texture varies slightly depending upon their preparation, but it can be generally described as rich and creamy. History Potatoes originated in the Andean mountain region of South America. Researchers estimate that potatoes have been cultivated by the Indians living in these areas for between 4,000 and 7,000 years. Unlike many other foods, potatoes were able to be grown at the high altitudes typical of this area and therefore became a staple food for these hardy people. Potatoes were brought to Europe by Spanish explorers who "discovered" them in South America in the early 16th century. Since potatoes are good sources of vitamin C, they were subsequently used on Spanish ships to prevent scurvy. They were introduced into Europe via Spain, and while they were consumed by some people in Italy and Germany, they were not widely consumed throughout Europe, even though many governments actively promoted this nutritious foodstuff that was relatively inexpensive to produce. The reason for this is that since people knew that the potato is related to the nightshade family, many felt that it was poisonous like some other members of this family. In addition, many judged potatoes with suspicion. In fact, potatoes initially had such a poor reputation in Europe that many people thought eating them would cause leprosy. Some of the credit for the rise in potatoes' popularity is given to two individuals who creatively engineered plans to create demand for the potato. In the 18th century, a French agronomist named Parmentier created a scheme whereby peasants could "steal" potatoes from the King's "guarded" gardens. He also developed and popularized the mashed potato that became popular probably because he made this suspicious vegetable unrecognizable. Another person who was instrumental to the acceptance of potatoes was Count Rumford. A member of the British scientific group, the Royal Society, Rumford created a mush soup made of potatoes, barley, peas and vinegar, which the German peasants adopted as a satisfying and inexpensive dish. It is thought that the potato was first brought to the United States in the early 18th century by Irish immigrants who settled in New England. People in this country were slow to adopt the "Irish potato" and large scale cultivation of potatoes did not occur in the U.S. until the 19th century. There are not that many foods that can claim that a pivotal historical event centered around them. But the potato can. By the early 19th century, potatoes were being grown extensively throughout Northern Europe, and potatoes were almost solely relied upon as a foodstuff in Ireland owing to this vegetable's inexpensive production and the poor economy of this country. Yet, in 1845 and 1846, a blight ruined most of the potato crop in Ireland and caused major devastation: this event is known as the Irish Potato Famine. Almost three-quarters of a million people died, and hundreds of thousands emigrated to other countries, including the United States, in search of sustenance. Today, this once-infamous vegetable is one of the most popular throughout the world and the one that Americans consume more of pound for pound than any other. Currently, the main producers of potatoes include the Russian Federation, Poland, India, China and the United States. How to Select and Store While potatoes are often conveniently packaged in a plastic bag, it is usually better to buy them individually from a bulk display. Not only will this allow you to better inspect the potatoes for signs of decay or damage, but many times, the plastic bags are not perforated and cause a build up of moisture that can negatively affect the potatoes. Potatoes should be firm, well shaped and relatively smooth, and should be free of decay that often manifests as wet or dry rot. In addition, they should not be sprouting or have green coloration since this indicates that they may contain the toxic alkaloid solanine that has been found to not only impart an undesirable taste, but can also cause a host of different health conditions such as circulatory and respiratory depression, headaches and diarrhea. Sometimes stores will offer already cleaned potatoes. These should be avoided since when their protective coating is removed by washing, potatoes are more vulnerable to bacteria. In addition, already cleaned potatoes are also more expensive, and since you will have to wash them again before cooking, you will be paying an unnecessary additional cost. Since new potatoes are harvested before they are fully mature, they are much more susceptible to damage. Be especially careful when purchasing these to buy ones that are free from discoloration and injury. The ideal way to store potatoes is in a dark, dry place between 45°F to 50°F between 7-10°C) as higher temperatures, even room temperature, will cause the potatoes to sprout and dehydrate prematurely. While most people do not have root cellars that provide this type of environment, to maximize the potato's quality and storage, you should aim to find a place as close as possible to these conditions. Storing them in a cool, dark closet or basement may be suitable alternatives. Potatoes should definitely not be exposed to sunlight as this can cause the development of the toxic alkaloid solanine to form. Potatoes should not be stored in the refrigerator, as their starch content will turn to sugar giving them an undesirable taste. In addition, do not store potatoes near onions, as the gases that they each emit will cause the degradation of one another. Wherever you store them, they should be kept in a burlap or paper bag. Mature potatoes stored properly can keep up to two months. Check on the potatoes frequently, removing any that have sprouted or shriveled as spoiled ones can quickly affect the quality of the others. New potatoes are much more perishable and will only keep for one week. Cooked potatoes will keep fresh in the refrigerator for several days. Potatoes do not freeze well. Tips for Preparing Potatoes: The potato skin is a concentrated source of dietary fiber, so to get the most nutritional value from this vegetable, don't peel it and consume both the flesh and the skin. Just scrub the potato under cold running water right before cooking and then remove any deep eyes or bruises with a paring knife. If you must peel it, do so carefully with a vegetable peeler, only removing a thin layer of the skin and therefore retaining the nutrients that lie just below the skin. Potatoes should be cleaned and cut right before cooking in order to avoid the discoloration that occurs with exposure to air. If you cannot cook them immediately after cutting, place them in a bowl of cold water to which you have added a little bit of lemon juice, as this will prevent their flesh from darkening and will also help to maintain their shape during cooking. As potatoes are also sensitive to certain metals that may cause them to discolor, avoid cooking them in iron or aluminum pots or using a carbon steel knife to cut them. A Few Quick Serving Ideas: -Purée roasted garlic, cooked potatoes and olive oil together to make delicious garlic mashed potatoes. Season to taste. -Potatoes are a featured ingredient in the classic dish, Salad Nicoise, that pairs new potatoes with chunks of tuna fish and steamed green beans dressed lightly with oil and vinegar. -Toss steamed, diced potato with olive oil and fresh herbs of your choice. -Cut lengthwise into 1/4 and rub with coconut oil and your favorite spices and salt, then bake at 375 for about 20-30 minutes, check for crispyness. -Dice and steam potatoes, then blend with water for a natural thickener for soups or sauces. Individual Concerns Potatoes Belong to the Nightshade Family Potatoes are one of the vegetables in the nightshade (Solanaceae) family, which includes eggplant, tomatoes and bell peppers. Anecdotal case histories link improvement in arthritis symptoms with removal of these foods;however, no case-controlled scientific studies confirm these observations. Nutritional Profile Potatoes are a very good source of vitamin C. They are also a good source of vitamin B6, copper, potassium, manganese, and dietary fiber. Health Food of the Week: Millet 01/13/2010
Health Benefits -Heart-Protective Properties -Development and Repair of Body Tissue -Millet and Other Whole Grains Substantially Lower Type 2 Diabetes Risk -Helps Prevent Gallstones -Fiber from Whole Grains and Fruit Protective against Breast Cancer -Whole Grains and Fish Highly Protective against Childhood Asthma -Health-Promoting Activity Equal to or Even Higher than that of Vegetables and Fruits -Lignans Protect against Heart Disease -Significant Cardiovascular Benefits for Postmenopausal Women -Prevent Heart Failure with a Whole Grains Breakfast -Meta-analysis Explains Whole Grains' Health Benefits Millet is more than just an interesting alternative to the more common grains, it is a good source of some very important nutrients, including manganese, phosphorus, and magnesium. Heart-Protective Properties Although oats have been widely publicized for their heart-protective properties, millet is a grain that should also be included on your list of heart-healthy choices because of its status as a good source of magnesium. Magnesium has been shown in studies to reduce the severity of asthma and to reduce the frequency of migraine attacks. Magnesium has also been shown to lower high blood pressure and reduce the risk of heart attack, especially in people with atherosclerosis or diabetic heart disease. Niacin (vitamin B3) can be of help in lowering high cholesterol. A cup of cooked millet provides 26.4% of the daily value for magnesium. Development and Repair of Body Tissue The phosphorus provided by millet plays a role in the structure of every cell in the body. In addition to its role in forming the mineral matrix of bone, phosphorus is an essential component of numerous other life-critical compounds including adenosine triphosphate or ATP, the molecule that is the energy currency of the body. Phosphorus is an important component of nucleic acids, the building blocks of the genetic code. In addition, the metabolism of lipids (fats) relies on phosphorus, and phosphorus is an essential component of lipid-containing structures such as cell membranes and nervous system structures. A cup of cooked millet will give you 24.0% of the daily value for phosphorus. Millet and Other Whole Grains Substantially Lower Type 2 Diabetes Risk Millet and other whole grains are a rich source of magnesium, a mineral that acts as a co-factor for more than 300 enzymes, including enzymes involved in the body's use of glucose and insulin secretion. The FDA permits foods that contain at least 51% whole grains by weight (and are also low in fat, saturated fat, and cholesterol) to display a health claim stating consumption is linked to lower risk of heart disease and certain cancers. Now, research suggests regular consumption of whole grains also reduces risk of type 2 diabetes. (van Dam RM, Hu FB, Diabetes Care). In this 8-year trial, involving 41,186 particpants of the Black Women's Health Study, research data confirmed inverse associations between magnesium, calcium and major food sources in relation to type 2 diabetes that had already been reported in predominantly white populations. Risk of type 2 diabetes was 31% lower in black women who frequently ate whole grains compared to those eating the least of these magnesium-rich foods. When the women's dietary intake of magnesium intake was considered by itself, a beneficial, but lesser- 19%- reduction in risk of type 2 diabetes was found, indicating that whole grains offer special benefits in promoting healthy blood sugar control. Daily consumption of low-fat dairy foods was also helpful, lowering risk of type 2 diabetes by 13%. Enjoy a hearty breakfast and get the benefits of both millet and dairy by serving a hot bowl of millet topped with low-fat milk and your favorite dried fruit, nuts or seeds. Helps Prevent Gallstones Eating foods high in insoluble fiber, such as millet, can help women avoid gallstones, shows a study published in the American Journal of Gastroenterology. Studying the overall fiber intake and types of fiber consumed over a 16 year period by over 69,000 women in the Nurses Health Study, researchers found that those consuming the most fiber overall (both soluble and insoluble) had a 13% lower risk of developing gallstones compared to women consuming the fewest fiber-rich foods. Those eating the most foods rich in insoluble fiber gained even more protection against gallstones: a 17% lower risk compared to women eating the least. And the protection was dose-related; a 5-gram increase in insoluble fiber intake dropped risk dropped 10%. How do foods rich in insoluble fiber help prevent gallstones? Researchers think insoluble fiber not only speeds intestinal transit time (how quickly food moves through the intestines), but reduces the secretion of bile acids (excessive amounts contribute to gallstone formation), increases insulin sensitivity and lowers triglycerides (blood fats). Abundant in all whole grains, insoluble fiber is also found in nuts and the edible skin of fruits and vegetables including tomatoes, cucumbers, many squash, apples, berries, and pears. In addition, beans provide insoluble as well as soluble fiber. Fiber from Whole Grains and Fruit Protective against Breast Cancer When researchers looked at how much fiber 35,972 participants in the UK Women's Cohort Study ate, they found a diet rich in fiber from whole grains, such as millet, and fruit offered significant protection against breast cancer for pre-menopausal women. (Cade JE, Burley VJ, et al., International Journal of Epidemiology). Pre-menopausal women eating the most fiber (>30 grams daily) more than halved their risk of developing breast cancer, enjoying a 52% lower risk of breast cancer compared to women whose diets supplied the least fiber (<20 grams/day). Fiber supplied by whole grains offered the most protection. Pre-menopausal women eating the most whole grain fiber (at least 13 g/day) had a 41% reduced risk of breast cancer, compared to those with the lowest whole grain fiber intake (4 g or less per day). Fiber from fruit was also protective. Pre-menopausal women whose diets supplied the most fiber from fruit (at least 6 g/day) had a 29% reduced risk of breast cancer, compared to those with the lowest fruit fiber intake (2 g or less per day). Practical Tip: As the following table shows, it's surprisingly easy to enjoy a healthy way of eating that delivers at least 13 grams of whole grain fiber and 6 grams of fiber from fruit each day.

Source: esha Research, Food Processor for Windows, Version 7.8 Whole Grains and Fish Highly Protective against Childhood Asthma According to the American Lung Association, almost 20 million Americans suffer from asthma, which is reported to be responsible for over 14 million lost school days in children, and an annual economic cost of more than $16.1 billion. Increasing consumption of whole grains and fish could reduce the risk of childhood asthma by about 50%, suggests the International Study on Allergy and Asthma in Childhood (Tabak C, Wijga AH, Thorax). The researchers, from the Dutch National Institute of Public Health and the Environment, Utrecht University, University Medical Center Groningen, used food frequency questionnaires completed by the parents of 598 Dutch children aged 8-13 years. They assessed the children's consumption of a range of foods including fish, fruits, vegetables, dairy and whole grain products. Data on asthma and wheezing were also assessed using medical tests as well as questionnaires. While no association between asthma and intake of fruits, vegetables, and dairy products was found (a result at odds with other studies that have supported a link between antioxidant intake, particularly vitamins C and E, and asthma), the children's intake of both whole grains and fish was significantly linked to incidence of wheezing and current asthma. In children with a low intake of fish and whole grains, the prevalence of wheezing was almost 20%, but was only 4.2% in children with a high intake of both foods. Low intake of fish and whole grains also correlated with a much higher incidence of current asthma (16.7%). compared to only a 2.8% incidence of current asthma among children with a high intake of both foods. After adjusting results for possible confounding factors, such as the educational level of the mother, and total energy intake, high intakes of whole grains and fish were found to be associated with a 54 and 66% reduction in the probability of being asthmatic, respectively. The probability of having asthma with bronchial hyperresponsiveness (BHR), defined as having an increased sensitivity to factors that cause narrowing of the airways, was reduced by 72 and 88% when children had a high-intake of whole grains and fish, respectively. Lead researcher, CoraTabak commented, "The rise in the prevalence of asthma in western societies may be related to changed dietary habits." We agree. The Standard American Diet is sorely deficient in the numerous anti-inflammatory compounds found in fish and whole grains, notably, the omega-3 fats supplied by cold water fish and the magnesium and vitamin E provided by whole grains. One caution: wheat may need to be avoided as it is a common food allergen associated with asthma. Health-Promoting Activity Equal to or Even Higher than that of Vegetables and Fruits Research reported at the American Institute for Cancer Research (AICR) International Conference on Food, Nutrition and Cancer, by Rui Hai Liu, M.D., Ph.D., and his colleagues at Cornell University shows that whole grains, such as millet, contain many powerful phytonutrients whose activity has gone unrecognized because research methods have overlooked them. Despite the fact that for years researchers have been measuring the antioxidant power of a wide array of phytonutrients, they have typically measured only the "free" forms of these substances, which dissolve quickly and are immediately absorbed into the bloodstream. They have not looked at the "bound" forms, which are attached to the walls of plant cells and must be released by intestinal bacteria during digestion before they can be absorbed. Phenolics, powerful antioxidants that work in multiple ways to prevent disease, are one major class of phytonutrients that have been widely studied. Included in this broad category are such compounds as quercetin, curcumin, ellagic acid, catechins, and many others that appear frequently in the health news. When Dr. Liu and his colleagues measured the relative amounts of phenolics, and whether they were present in bound or free form, in common fruits and vegetables like apples, red grapes, broccoli and spinach, they found that phenolics in the "free" form averaged 76% of the total number of phenolics in these foods. In whole grains, however, "free" phenolics accounted for less than 1% of the total, while the remaining 99% were in "bound" form. In his presentation, Dr. Liu explained that because researchers have examined whole grains with the same process used to measure antioxidants in vegetables and fruits-looking for their content of "free" phenolics"-the amount and activity of antioxidants in whole grains has been vastly underestimated. Despite the differences in fruits', vegetables' and whole grains' content of "free" and "bound" phenolics, the total antioxidant activity in all three types of whole foods is similar, according to Dr. Liu's research. His team measured the antioxidant activity of various foods, assigning each a rating based on a formula (micromoles of vitamin C equivalent per gram). Broccoli and spinach measured 80 and 81, respectively; apple and banana measured 98 and 65; and of the whole grains tested, corn measured 181, whole wheat 77, oats 75, and brown rice 56. Dr. Liu's findings may help explain why studies have shown that populations eating diets high in fiber-rich whole grains consistently have lower risk for colon cancer, yet short-term clinical trials that have focused on fiber alone in lowering colon cancer risk, often to the point of giving subjects isolated fiber supplements, yield inconsistent results. The explanation is most likely that these studies have not taken into account the interactive effects of all the nutrients in whole grains-not just their fiber, but also their many phytonutrients. As far as whole grains are concerned, Dr. Liu believes that the key to their powerful cancer-fighting potential is precisely their wholeness. A grain of whole wheat consists of three parts-its endosperm (starch), bran and germ. When wheat-or any whole grain-is refined, its bran and germ are removed. Although these two parts make up only 15-17% of the grain's weight, they contain 83% of its phenolics. Dr. Liu says his recent findings on the antioxidant content of whole grains reinforce the message that a variety of foods should be eaten good health. "Different plant foods have different phytochemicals," he said. "These substances go to different organs, tissues and cells, where they perform different functions. What your body needs to ward off disease is this synergistic effect - this teamwork - that is produced by eating a wide variety of plant foods, including whole grains." Lignans Protect against Heart Disease One type of phytonutrient especially abundant in whole grains including millet are plant lignans, which are converted by friendly flora in our intestines into mammalian lignans, including one called enterolactone that is thought to protect against breast and other hormone-dependent cancers as well as heart disease. In addition to whole grains, nuts, seeds and berries are rich sources of plant lignans, and vegetables, fruits, and beverages such as coffee, tea and wine also contain some. When blood levels of enterolactone were measured in over 800 postmenopausal women in a Danish study published in the Journal of Nutrition, women eating the most whole grains were found to have significantly higher blood levels of this protective lignan. Women who ate more cabbage and leafy vegetables also had higher enterolactone levels. Significant Cardiovascular Benefits for Postmenopausal Women Eating a serving of whole grains, such as millet, at least 6 times each week is an especially good idea for postmenopausal women with high cholesterol, high blood pressure or other signs of cardiovascular disease (CVD). A 3-year prospective study of 229 postmenopausal women with CVD, published in the American Heart Journal, shows that those eating at least 6 servings of whole grains each week experienced both: Slowed progression of atherosclerosis, the build-up of plaque that narrows the vessels through which blood flows, and Less progression in stenosis, the narrowing of the diameter of arterial passageways. The women's intake of fiber from fruits, vegetables and refined grains was not associated with a lessening in CVD progression. Prevent Heart Failure with a Whole Grains Breakfast Heart failure is the leading cause of hospitalization among the elderly in the United States. Success of drug treatment is only partial (ACE inhibitors and beta-blockers are typically used; no evidence has found statins safe or effective for heart failure), and its prognosis remains poor. Follow up of 2445 discharged hospital patients with heart failure revealed that 37.3% died during the first year, and 78.5% died within 5 years. Arch Intern Med. 2007 Mar 12;167(5):490-6.;Eur Heart J. 2006 Mar;27(6):641-3. Since consumption of whole grain products and dietary fiber has been shown to reduce the risk of high blood pressure and heart attack, Harvard researchers decided to look at the effects of cereal consumption on heart failure risk and followed 21,376 participants in the Physicians Health Study over a period of 19.6 years. After adjusting for confounding factors (age, smoking, alcohol consumption, vegetable consumption, use of vitamins, exercise, and history of heart disease), they found that men who simply enjoyed a daily morning bowl of whole grain (but not refined) cereal had a 29% lower risk of heart failure. Arch Intern Med. 2007 Oct 22;167(19):2080-5. Isn't your heart worth protecting, especially when the prescription-a morning bowl of hearty whole grains-is so delicious?

Meta-analysis Explains Whole Grains' Health Benefits In many studies, eating whole grains, such as millet, has been linked to protection against atherosclerosis, ischemic stroke, diabetes, insulin resistance, obesity, and premature death. A new study and accompanying editorial, published in the American Journal of Clinical Nutrition explains the likely reasons behind these findings and recommends at least 3 servings of whole grains should be eaten daily. Whole grains are excellent sources of fiber. In this meta-analysis of 7 studies including more than 150,000 persons, those whose diets provided the highest dietary fiber intake had a 29% lower risk of cardiovascular disease compared to those with the lowest fiber intake. But it's not just fiber's ability to serve as a bulking agent that is responsible for its beneficial effects as a component of whole grains. Wheat bran, for example, which constitutes 15% of most whole-grain wheat kernels but is virtually non-existent in refined wheat flour, is rich in minerals, antioxidants, lignans, and other phytonutrients;mdash;as well as in fiber. In addition to the matrix of nutrients in their dietary fibers, the whole-grain arsenal includes a wide variety of additional nutrients and phytonutrients that reduce the risk of cardiovascular disease. Compounds in whole grains that have cholesterol-lowering effects include polyunsaturated fatty acids, oligosaccharides, plant sterols and stanols, and saponins. Whole grains are also important dietary sources of water-soluble, fat-soluble, and insoluble antioxidants. The long list of cereal antioxidants includes vitamin E, tocotrieonols, selenium, phenolic acids, and phytic acid. These multifunctional antioxidants come in immediate-release to slow-release forms and thus are available throughout the gastrointestinal tract over a long period after being consumed. The high antioxidant capacity of wheat bran, for example, is 20-fold that of refined wheat flour (endosperm). Although the role of antioxidant supplements in protecting against cardiovascular disease has been questioned, prospective population studies consistently suggest that when consumed in whole foods, antioxidants are associated with significant protection against cardiovascular disease. Because free radical damage to cholesterol appears to contribute significantly to the development of atherosclerosis, the broad range of antioxidant activities from the phytonutrients abundant in whole-grains is thought to play a strong role in their cardio-protective effects. Like soybeans, whole grains are good sources of phytoestrogens, plant compounds that may affect blood cholesterol levels, blood vessel elasticity, bone metabolism, and many other cellular metabolic processes. Whole grains are rich sources of lignans that are converted by the human gut to enterolactone and enterodiole. In studies of Finnish men, blood levels of enterolactone have been found to have an inverse relation not just to cardiovascular-related death, but to all causes of death, which suggests that the plant lignans in whole grains may play an important role in their protective effects. Lower insulin levels may also contribute to the protective effects of whole grains. In many persons, the risks of atherosclerotic cardiovascular disease, diabetes, and obesity are linked to insulin resistance. Higher intakes of whole grains are associated with increased sensitivity to insulin in population studies and clinical trials. Why? Because whole grains improve insulin sensitivity by lowering the glycemic index of the diet while increasing its content of fiber, magnesium, and vitamin E. The whole kernel of truth: as part of your healthy way of eating, whole grains, such as millet, can significantly lower your risk of cardiovascular disease, obesity and type 2 diabetes. The 2005 Dietary Guidelines for Americans recommends at least 3 servings of whole-grain foods each day, but experts say most Americans eat less than a single serving. Don't be part of this majority! No idea how to cook whole grains? Just look at the "How to Enjoy" section below. Description While you will probably recognize millet as being one of the main ingredients in birdseed, this wonderful grain is anything but "for the birds." (Millet is technically a seed and not a grain but we classify it as a grain on our website since that is what it is categorized as from a culinary perspective.) It is a delicious grain whose consistency varies depending upon cooking method; it can be creamy like mashed potatoes or fluffy like rice. Additionally, since millet does not contain gluten, it is a wonderful grain alternative for people who are gluten-sensitive. Millet is tiny in size and round in shape and can vary in color from white to gray to yellow to red. The most widely available form of millet found in stores is the pearled, hulled type, although oftentimes you may be able to find traditional couscous, which is made from cracked millet. The term millet refers to a variety of grains, some of which do not belong to the same genus of plant. The types of millet consumed as food generally fall into the scientific categories Panicum miliaceuem or Setaria italica. History Millet is thought to have originated in North Africa, specifically in Ethiopia, where it has been consumed since prehistoric times. There is even mention of millet in the Bible as an ingredient for unleavened bread. Millet is still an extremely important food staple in Africa where finely ground millet is used to make a traditional flatbread known as injera. Since ancient times, millet has been widely consumed in Asia and India as well. The Indian flatbread roti is made from ground millet seeds. In the Middle Ages, before potatoes and corn were introduced, millet became a staple grain in Europe, especially in countries in Eastern Europe. The Setaria variety of millet was introduced into the United States in the 19th century. While millet has been used primarily for birdseed and livestock fodder in Western Europe and North America, it is now gaining popularity as a delicious and nutritious grain that can be enjoyed for both its unique virtues as well as the fact that it is a gluten-free grain alternative to wheat. The majority of the world's commercial millet crop is produced by India, China and Nigeria. How to Select and Store Millet is generally available in its hulled and whole-grain form. It is available prepackaged as well as in bulk containers. Just as with any other food that you may purchase in the bulk section, make sure that the bins containing the millet are covered and that the store has a good product turnover so as to ensure its maximal freshness. Whether purchasing millet in bulk or in a packaged container, make sure that there is no evidence of moisture. Store millet in an airtight container in a cool, dry and dark place, where it will keep for several months. Tips for Preparing Millet: Like all grains, before cooking millet rinse it thoroughly under running water and then remove any dirt or debris that you may find. After rinsing, add one part millet to two parts boiling water or broth. After the liquid has returned to a boil, turn down the heat, cover and simmer for about 25 minutes. The texture of millet cooked this way will be fluffy like rice. If you want the millet to have a more creamy consistency, stir it frequently adding a little water every now and then. To impart a nuttier flavor to the cooked millet, you could roast the grains first before boiling. To do this, place the grains in a dry skillet over medium heat and stir them frequently. When they have achieved a golden color, add them to the boiling cooking liquid. A Few Quick Serving Ideas: Cooked millet can be served as a breakfast porridge to which you can add your favorite nuts and fruits. Ground millet can be added to bread and muffin recipes. Toss cooked and chilled millet with your favorite chopped vegetables and either chicken or baked tofu cubes. Add dressing and voilà ..... an easy to prepare, delicious meal. Next time you are looking for an alternative to rice or potatoes, serve millet instead. Make a millet polenta. Cook and stir heavily to make a thick porridge consistancy (adding liquids as needed), add flavorings (sweet or savory) and butter. Spread evenly in an oiled pan and allowed to cool. Cut in to shapes and serve, or bake/sautee untill crispy. Finely ground millet makes for a great thickener for soups, sauces, etc... Make injera bread (a flat and tart pancake). Add two parts water to one part millet flour, with 2 tablespoons whey starter (or lemon juice) and allow to sit in a warm place for 2 days. Strain off excess water on top of mix and stir well, pour enough to cover a hot pan bottom and wait untill it stiffens up and bubbles appear all over the bread before turning. Regulate heat of pan by removing it from the heat for a time to prevent the bread from burning. Coat the bread lightly with clarified butter or oil and allow to set before eating. Freezes well and can be used as a wrap or to accompany a variety of dishes. Health food of the Week: Carrots 01/06/2010
Health Benefits Carotenoids and Heart Disease Better Vision Carotenoids and Optimal Health Carotenoids and Blood Sugar Falcarinol in Carrots Promote Colon Health Promote Lung Health Nutritional Profile Carrots are an excellent source of vitamin A. In addition, they are a very good source of vitamin C, vitamin K, dietary fiber and potassium. Carrots are an excellent source of antioxidant compounds, and the richest vegetable source of the pro-vitamin A carotenes.The common orange carrot has 686.3% of your RDA of vitamin A per 1 cup serving! Carrots' antioxidant compounds help protect against cardiovascular disease and cancer and also promote good vision, especially night vision. Carotenoids and Heart Disease When six epidemiological studies that looked at the association of diets high in carotenoids and heart disease were reviewed, the research demonstrated that high-carotenoid diets are associated with a reduced risk of heart disease. In one study that examined the diets of 1,300 elderly persons in Massachusetts, those who had at least one serving of carrots and/or squash each day had a 60% reduction in their risk of heart attacks compared to those who ate less than one serving of these carotenoid-rich foods per day. Better Vision Beta-carotene helps to protect vision, especially night vision. After beta-carotene is converted to vitamin A in the liver, it travels to the retina where it is transformed into rhodopsin, a purple pigment that is necessary for night-vision. Plus beta-carotene's powerful antioxidant actions help provide protection against macular degeneration and the development of senile cataracts, the leading cause of blindness in the elderly. Carotenoids and Optimal Health Carrots are by far one of the richest source of carotenoids-just one cup provides 16,679 IUs of beta-carotene and 3,432 REs (retinol equivalents), or roughly 686.3% the RDA for vitamin A. High carotenoid intake has been linked with a 20% decrease in postmenopausal breast cancer and an up to 50% decrease in the incidence of cancers of the bladder, cervix, prostate, colon, larynx, and esophagus. Extensive human studies suggest that a diet including as little as one carrot per day could conceivably cut the rate of lung cancer in half. Remember the study in which heavy long-term cigarette smokers were given synthetic beta-carotene, and it did not appear to prevent them from developing lung cancer? Well, not only is synthetic beta-carotene not biochemically identical to the real stuff found in carrots, but scientists now think that carrots' protective effects are the result of a team effort among several substances abundant in carrots, including alpha-carotene-another, less publicized carotenoid. A recent National Cancer Institute study found lung cancer occurence was higher in men whose diets did not supply a healthy intake of alpha-carotene. Carotenoids and Blood Sugar Intake of foods such as carrots that are rich in carotenoids may be beneficial to blood sugar regulation. Research has suggested that physiological levels, as well as dietary intake, of carotenoids may be inversely associated with insulin resistance and high blood sugar levels. Falcarinol in Carrots Promote Colon Health Although best known for their high content of beta carotene, carrots also contain a phytonutrient called falcarinol that may be responsible for the recognized epidemiological association between frequently eating carrots and a reduced risk of cancers. Falcarinol provides protection against colon cancer, suggests a study published in the Journal of Agricultural and Food Chemistry. Three groups of laboratory animals in whom precancerous colon lesions (aberrant crypt foci) had been chemically-induced were fed a standard diet, one supplemented with freeze-dried carrots naturally containing falcarinol, or one supplemented with an extract of falcarinol. After 18 weeks, precancerous lesions in the animals given diets containing carrots or falcarinol were much smaller than those in the control animals, and far fewer of the lesions had grown in size or progressed to become tumors. Promote Lung Health If you or someone you love is a smoker, or if you are frequently exposed to secondhand smoke, then making vitamin A-rich foods, such as carrots, part of your healthy way of eating may save your life, suggests research conducted at Kansas State University. While studying the relationship between vitamin A, lung inflammation, and emphysema, Richard Baybutt, associate professor of nutrition at Kansas State, made a surprising discovery: a common carcinogen in cigarette smoke, benzo(a)pyrene, induces vitamin A deficiency. Baybutt's earlier research had shown that laboratory animals fed a vitamin A-deficient diet developed emphysema. His latest animal studies indicate that not only does the benzo(a)pyrene in cigarette smoke cause vitamin A deficiency, but that a diet rich in vitamin A can help counter this effect, thus greatly reducing emphysema. Baybutt believes vitamin A's protective effects may help explain why some smokers do not develop emphysema. "There are a lot of people who live to be 90 years old and are smokers," he said. "Why? Probably because of their diet…The implications are that those who start smoking at an early age are more likely to become vitamin A deficient and develop complications associated with cancer and emphysema. And if they have a poor diet, forget it." If you or someone you love smokes, or if your work necessitates exposure to second hand smoke, protect yourself by making sure the World's Healthiest Foods rich in vitamin A (carrot's beta-carotene is converted in the body into vitamin A) are a daily part of your healthy way of eating. Description Carrots? The favorite food of Bugs Bunny hardly needs a description for they are well known and loved by even the youngest children in many countries. Carrots benefits are legendary. Bet your mother told you that eating carrots would keep your eyesight bright. While we usually associate carrots with the color orange, in fact, carrots grow in a host of other colors including white, yellow, red, or purple, the latter being the color of the original variety. The carrot is a plant with a thick, fleshy, deeply colored root, which grows underground, and feathery green leaves that emerge above ground. It is known scientifically as Daucus carota, a name that can be traced back to ancient Roman writings of the 3rd century. Carrots belong to the Umbelliferae family, named after the umbrella like flower clusters that plants in this family produce. As such, carrots are related to parsnips, fennel caraway, cumin and dill. There are over 100 different varieties that vary in size and color. Carrots can be as small as two inches or as long as three feet, ranging in diameter from one-half of an inch to over two inches. Carrot roots have a crunchy texture and a sweet and minty aromatic taste, while the greens are fresh tasting and slightly bitter. History The carrot can trace its ancestry back thousands of years, originally having been cultivated in central Asian and Middle Eastern countries. These original carrots looked different from those that we are accustomed to today, featuring deep purple coloring, ranging from lavender to deep eggplant. This coloration was a reflection of the anthocyanin phytonutrient pigments these carrots had. In pre-Hellenic times, a yellow-rooted carrot variety appeared in Afghanistan and was further cultivated and developed into an earlier version of the carrot we known today. Both types of carrots spread throughout the Mediterranean region and were adopted by the ancient Greeks and Romans for their medicinal use. It seems that carrots did not become a popular vegetable in Europe until the Renaissance. This was probably related to the fact that the early varieties had a tough and fibrous texture. Centuries later, beginning in the 17th century, agriculturists in Europe started cultivating different varieties of carrots, developing an orange-colored carrot that had a more pleasing texture than its predecessor. Europeans favored the growing of this one over the purple variety, which was and still is widely grown in other areas of the world, including southern Asia and North Africa. Carrots were subsequently introduced into the North American colonies. Owing to its heightened popularity, in the early 1800s, the carrot became the first vegetable to be canned. Today, the United States, France, England, Poland, China and Japan are among the largest producers of carrots. How to Select and Store Carrot roots should be firm, smooth, relatively straight and bright in color. The deeper the orange-color, the more beta-carotene is present in the carrot. Avoid carrots that are excessively cracked or forked as well as those that are limp or rubbery. In addition, if the carrots do not have their tops attached, look at the stem end and ensure that it is not darkly colored as this is also a sign of age. If the green tops are attached, they should be brightly colored, feathery and not wilted. Since the sugars are concentrated in the carrots' core, generally those with larger diameters will have a larger core and therefore be sweeter. Carrots are hardy vegetables that will keep longer than many others if stored properly. The trick to preserving the freshness of carrot roots is to minimize the amount of moisture they lose. To do this, make sure to store them in the coolest part of the refrigerator in a plastic bag or wrapped in a paper towel, which will reduce the amount of condensation that is able to form. They should be able to keep fresh for about two weeks. Carrots should also be stored away from apples, pears, potatoes and other fruits and vegetables that produce ethylene gas since it will cause them to become bitter. If you purchase carrot roots with attached green tops, the tops should be cut off before storing in the refrigerator since they will cause the carrots to wilt prematurely as they pull moisture from the roots. While the tops can be stored in the refrigerator, kept moist by being wrapped in a damp paper, they should really be used soon after purchase since they are fragile and will quickly begin to wilt. Tips for Preparing Carrots: Wash carrot roots and gently scrub them with a vegetable brush right before eating. Unless the carrots are old, thick or not grown organically, it is not necessary to peel them. If they are not organically grown, peel them; most all conventionally grown carrots are grown using pesticides and other chemicals. If the stem end is green, it should be cut away as it will be bitter. Depending upon the recipe or your personal preference, carrots can be left whole or julienned, grated, shredded or sliced into sticks or rounds. Carrots are delicious eaten raw or cooked. Beta-carotene is not destroyed by cooking; in fact, cooking breaks down the fiber, making this nutrient and carrots' sugars more available, thus also making them taste sweeter. Take care not to overcook carrots, however, to ensure that they retain their maximum flavor and nutritional content. A Few Quick Serving Ideas: Shredded raw carrots and chopped carrot greens make great additions to salads. Combine shredded carrots, beets and apples, and eat as a salad. For quick, nutritious soup that can be served hot or cold, purée boiled carrots and potatoes in a blender or food processor, and add herbs and spices to taste. Spiced carrot sticks are a flavorful variation on an old favorite at parties or at the dinner table. Soak carrot sticks in hot water spiced with cayenne, coriander seeds and salt. Allow to cool, drain and serve. Combine freshly squeezed carrot juice with raw milk or nutmilk and bananas to make a nutrient-dense breakfast shake. Don't Through out those limp carrots, they make great stock! as long as there is no molding toss them in large pot with chopped celery and onions along with any of your extra veggie trimmings (like kale stems, cabbage hearts...) cover with water and simmer for at least 1 hour to over night, Strain and use the broth for any of your cooking needs. Puree raw carrots in a food processor, with onions and curry spice and a little sea salt. mix with twice the volume of soaked flax seeds, spread thin on a dehydrator sheet or cookie sheet and dehydrate untill very dry and crisp for a great veggie chip. Cautions: Carrots and Carotoderma Excessive consumption of carotene-rich foods may lead to a condition called carotoderma in which the palms or other skin develops a yellow or orange cast. This yellowing of the skin is presumably related to carotenemia, excessive levels of carotene in the blood. The health impact of carotenemia is not well researched. Eating or juicing high amounts of foods rich in carotene, like carrots, may over tax the body's ability to convert these foods to vitamin A. The body slowly converts carotene to vitamin A, and extra carotene is stored, usually in the palms, soles or behind the ears. If the cause of the carotenemia is eating excessively high amounts of foods like carrots, the condition will usually disappear after reducing consumption. Health food of the week: Cauliflower 12/09/2009
Health food of the week: Cauliflower Health Benefits Sulfur-Containing Phytonutrients Promote Liver Detoxification How Cruciferous Vegetables Help Prevent Cancer Optimize Your Cells' Detoxification / Cleansing Ability A Weekly Serving of Cruciferous Vegetables Halves Advanced Prostate Cancer Risk Spicing Your Cauliflower with Turmeric Could Help Promote Men's Health Protection against Rheumatoid Arthritis Cardiovascular Benefits Cauliflower and other cruciferous vegetables, such as broccoli, cabbage, and kale, contain compounds that may help prevent cancer. These compounds appear to stop enzymes from activating cancer-causing agents in the body, and they increase the activity of enzymes that disable and eliminate carcinogens. Epidemiological studies have long suggested a connection between these vegetables and resistance to cancer. However, only in the past decade have we begun to understand how these compounds work. Sulfur-Containing Phytonutrients Promote Liver Detoxification We now know that cruciferous vegetables contain both glucosinolates and thiocyanates (including sulforaphane and isothiocyanate). These compounds increase the liver's ability to neutralize potentially toxic substances. If potentially toxic molecules are not properly and rapidly detoxified in the liver, they can damage cell membranes and molecules such as DNA within the cell nucleus. Such damage can start a chain reaction that may eventually lead to carcinogenesis-cell deregulation and uncontrolled growth. Many enzymes found in cauliflower also help with the detoxifying process. These enzymes include glutathione transferase, glucuronosyl transferase, and quinone reductase. Both animal and human studies show increased detoxification enzyme levels from high-glucosinolate diets. Researchers suggest that this helps explain the epidemiological association between a high intake of cruciferous vegetables and a decreased risk of certain cancers. How Cruciferous Vegetables Help Prevent Cancer New research has greatly advanced scientists' understanding of just how cruciferous vegetables such as cabbage, cauliflower, broccoli, kale and Brussels sprouts help prevent cancer. When these vegetables are cut, chewed or digested, a sulfur-containing compound called sinigrin is brought into contact with the enzyme myrosinase, resulting in the release of glucose and breakdown products, including highly reactive compounds called isothiocyanates. Isothiocyanates are not only potent inducers of the liver's Phase II enzymes, which detoxify carcinogens, but research recently conducted at the Institute for Food Research in the U.K. shows one of these compounds, allyl isothicyanate, also inhibits mitosis (cell division) and stimulates apoptosis (programmed cell death) in human tumor cells. Sulforaphane, a compound formed when cruciferous vegetables are chopped or chewed, is already known to trigger the liver to produce enzymes that detoxify cancer-causing chemicals, inhibit chemically-induced breast cancers in animal studies, and induce colon cancer cells to commit suicide. An in vitro study published in the Journal of Nutrition suggests that sulforaphane can also help stop the proliferation of breast cancer cells, even in the later stages of their growth. Sulforaphane may also offer special protection to those with colon cancer-susceptible genes, suggests a study conducted at Rutgers University and published online on May 4, 2006, in the journal Carcinogenesis. In this study, researchers sought to learn whether sulforaphane could inhibit cancers arising from one's genetic makeup. Rutgers researchers Ernest Mario, Ah-Ng Tony Kong and colleagues used mice bred with a genetic mutation that switches off the tumor suppressor gene known as APC, the same gene that is inactivated in the majority of human colon cancers. Animals with this mutation spontaneously develop intestinal polyps, the precursors to colon cancer. The study found that animals who were fed sulforaphane had tumors that were smaller, grew more slowly and had higher apoptotic (cell suicide) indices. Additionally, those fed a higher dose of sulforaphane had less risk of developing polyps than those fed a lower dose. The researchers found that sulforaphane suppressed certain kinase enzymes. These cell signaling enzymes are expressed not only in laboratory animals, but also in humans, and the ones supppressed by sulforaphane are involved in activities that promote colon cancer. According to lead researcher, Dr. Kong, "Our study corroborates the notion that sulforaphane has chemopreventive activity…Our research has substantiated the connection between diet and cancer prevention, and it is now clear that the expression of cancer-related genes can be influenced by chemopreventive compounds in the things we eat." Human population as well as animal studies consistently show that diets high in cruciferous vegetables, such as cauliflower, are associated with lower incidence of certain cancers, including lung, colon, breast and ovarian cancer. Now, research published in the International Journal of Cancer (Zhao H, Lin J) suggests that bladder cancer can join the list. University of Texas researchers analyzed the diets of 697 newly diagnosed bladder cancer cases and 708 healthy controls matched by age, gender and ethnicity. Average daily intake of cruciferous vegetables was significantly lower in those with bladder cancer than in healthy controls. Those eating the most cruciferous vegetables were found to have a 29% lower risk of bladder cancer compared to participants eating the least of this family of vegetables. Crucifers' protective benefits were even more pronounced in three groups typically at higher risk for bladder cancer: men, smokers, and older individuals (aged at least 64). Diagnosed in about 336,000 people every year worldwide, bladder cancer is three times more likely to affect men than women, according to the European School of Oncology. Crucifers' well known cancer-fighting properties are thought to result from their high levels of active phytochemicals called glucosinolates, which our bodies metabolize into powerful anti-carcinogens called isothiocyanates. Isothiocyanates offer the bladder, in particular, significant protection, most likely because the majority of compounds produced by isothiocyanate metabolism travel through the bladder en route to excretion in the urine, suggested the researchers. Optimize Your Cells' Detoxification / Cleansing Ability For about 20 years, we've known that many phytonutrients work as antioxidants to disarm free radicals before they can damage DNA, cell membranes and fat-containing molecules such as cholesterol. Now, new research is revealing that phytonutrients in crucifers, such as cauliflower, work at a much deeper level. These compounds actually signal our genes to increase production of enzymes involved in detoxification, the cleansing process through which our bodies eliminate harmful compounds. The phytonutrients in cruciferous vegetables initiate an intricate dance inside our cells in which gene response elements direct and balance the steps among dozens of detoxification enzyme partners, each performing its own protective role in perfect balance with the other dancers. The natural synergy that results optimizes our cells' ability to disarm and clear free radicals and toxins, including potential carcinogens, which may be why crucifers appear to lower our risk of cancer more effectively than any other vegetables or fruits. Recent studies show that those eating the most cruciferous vegetables have a much lower risk of prostate, colorectal and lung cancer-even whencompared to those who regularly eat other vegetables: In a study of over 1,200 men, conducted at the Fred Hutchinson Cancer Research Center in Seattle, WA, those eating 28 servings of vegetables a week had a 35% lower risk of prostate cancer, but those consuming just 3 or more servings of cruciferous vegetables each week had a 44% lower prostate cancer risk. In the Netherlands Cohort Study on Diet and Cancer, in which data was collected on over 100,000 people for more than 6 years, those eating the most vegetables benefited with a 25% lower risk of colorectal cancers, but those eating the most cruciferous vegetables did almost twice as well with a 49% drop in their colorectal cancer risk. A study of Chinese women in Singapore, a city in which air pollution levels are often high putting stress on the detoxification capacity of residents' lungs, found that in non-smokers, eating cruciferous vegetables lowered risk of lung cancer by 30%. In smokers, regular cruciferous vegetable consumption reduced lung cancer risk an amazing 69%! How many weekly servings of cruciferous vegetables do you need to lower your risk of cancer? Just 3 to 5 servings-less than one serving a day! (1 serving = 1 cup) To get the most benefit from your cruciferous vegetables like cauliflower, be sure to choose organically grown varieties (their phytonutrient levels are higher than conventionally grown), and steam lightly (this method of cooking has been shown to not only retain the most phytonutrients but to maximize their availability). For a brief overview of the process through which cruciferous vegetables boost our ability to detoxify or cleanse harmful compounds and examples of how specific phytonutrients in crucifers work together to protect us against cancer, see our FAQ: Optimizing Your Cells' Detoxification/Cleansing Ability by Eating Cruciferous Vegetables. A Weekly Serving of Cruciferous Vegetables Halves Advanced Prostate Cancer Risk A study of 29,361 men, enrolled on the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial found that men who ate more than a serving of either broccoli or cauliflower each week almost halved their risk of developing advanced-stage prostate cancer (cancer that had spread beyond the prostate gland), compared with their peers who ate these vegetables less than once a month. Specifically, compared to men eating broccoli just once a month, those eating a weekly serving lowered their risk of advanced prostate cancer by 45%. Cauliflower was even a bit more protective. Compared to men eating one serving of cauliflower per month, those enjoying a weekly serving lowered their risk of advanced prostate cancer by 52%. (Kirsch VA, Peters U. et al., J Natl Cancer Inst.) Spicing Your Cauliflower with Turmeric Could Help Promote Men's Health Prostate cancer-the second leading cause of cancer death in American men with 500,000 new cases appearing each year-is a rare occurrence among men in India, whose low risk is attributed to a diet rich in Brassica family vegetables and the curry spice, turmeric. Scientists tested turmeric, a concentrated source of the phytonutrient curcumin, along with phenethyl isothiocyanates, a phytonutrient abundant in cruciferous vegetables including cauliflower, cabbage, broccoli, Brussels sprouts, kale, kohlrabi and turnips. When tested singly, both phenethyl isothiocyanate and curcumin greatly retarded the growth of human prostate cancer cells implanted in immune-deficient laboratory animals. In animals with well-established prostate cancer tumors, neither phenethyl isothiocyanate nor curcumin by itself had a protective effect, but when combined, they significantly reduced both tumor growth and the ability of the prostate cancer cells to spread (metastasize) in the test animals. The researchers believe the combination of cruciferous vegetables and curcumin could be an effective therapy not only to prevent prostate cancer, but to inhibit the spread of established prostate cancers. Best of all, this combination-cauliflower spiced with turmeric-is absolutely delicious! The best way to prepare it is to cut cauliflower florets in quarters and let them sit for 5-10 minutes; this allows time for the production of phenethyl isothiocyanates, which form when cruciferous vegetables are cut, but stops when they are heated. Then sprinkle with turmeric, and healthy sauté on medium heat in a few tablespoons of vegetable or chicken broth for 5 minutes. Remove from the heat and top with olive oil, sea salt and pepper to taste. Protection against Rheumatoid Arthritis While one study suggests that high doses of supplemental vitamin C makes osteoarthritis, a type of degenerative arthritis that occurs with aging, worse in laboratory animals, another indicates that vitamin C-rich foods, such as cauliflower, provide humans with protection against inflammatory polyarthritis, a form of rheumatoid arthritis involving two or more joints. The findings, presented in the Annals of the Rheumatic Diseases were drawn from a study of more than 20,000 subjects who kept diet diaries and were arthritis-free when the study began, and focused on subjects who developed inflammatory polyarthritis and similar subjects who remained arthritis-free during the follow-up period. Subjects who consumed the lowest amounts of vitamin C-rich foods were more than three times more likely to develop arthritis than those who consumed the highest amounts. Cardiovascular Benefits Consumption of cruciferous vegetables, such as cauliflower, is known to reduce the risk of a number of cancers, especially lung, colon, breast, ovarian and bladder cancer. Now, research reveals that crucifers provide significant cardiovascular benefits as well. Researchers from the University of Hawaii have shown that, at the tiny concentration of just 100 micromoles per liter, a phytonutrient found in cruciferous vegetables, indole-3-carbinol, lowers liver cells' secretion of the cholesterol transporter, apolipoproteinB-100 by 56%! Apolipoprotein B-100 (apoB) is the main carrier of LDL cholesterol to tissues, and high levels have been linked to plaque formation in the blood vessels. When liver cells were treated with I-3-C, not only was apoB-100 secretion cut by more than half, but significant decreases also occurred in the synthesis of lipids (fats), including triglycerides and cholesterol esters. (Maiyoh GK, Kuh JE, et al., J Nutr.) Description Cauliflower, a cruciferous vegetable, is in the same plant family as broccoli, kale, cabbage and collards. It has a compact head (called a "curd"), with an average size of six inches in diameter, composed of undeveloped flower buds. The flowers are attached to a central stalk. When broken apart into separate buds, cauliflower looks like a little tree, something that many kids are fascinated by. Surrounding the curd are ribbed, coarse green leaves that protect it from sunlight, impeding the development of chlorophyll. While this process contributes to the white coloring of most of the varieties, cauliflower can also be found in light green and purple colors. Between these leaves and the florets are smaller, tender leaves that are edible. Raw cauliflower is firm yet a bit spongy in texture. It has a slightly sulfurous and faintly bitter flavor. History Cauliflower traces its ancestry to the wild cabbage, a plant thought to have originated in ancient Asia Minor, which resembled kale or collards more than the vegetable that we now know it to be. The cauliflower went through many transformations and reappeared in the Mediterranean region, where it has been an important vegetable in Turkey and Italy since at least 600 B.C. It gained popularity in France in the mid-16th century and was subsequently cultivated in Northern Europe and the British Isles. The United States, France, Italy, India and China are countries that produce significant amounts of cauliflower. How to Select and Store When purchasing cauliflower, look for a clean, creamy white, compact curd in which the bud clusters are not separated. Spotted or dull-colored cauliflower should be avoided, as well as those in which small flowers appear. Heads that are surrounded by many thick green leaves are better protected and will be fresher. As its size is not related to its quality, choose one that best suits your needs. Store uncooked cauliflower in a paper or plastic bag in the refrigerator where it will keep for up to a week. To prevent moisture from developing in the floret clusters, store it with the stem side down. If you purchase pre-cut cauliflower florets, consume them within one or two days as they will lose their freshness after that. Since cooking causes cauliflower to spoil quicker, consume it within two to three days of placing in the refrigerator after cooking. Tips for preparing cauliflower Cauliflower florets are the part of the plant that most people eat. However, the stem and leaves are edible too and are especially good for adding to soup stocks. To cut cauliflower, first remove the outer leaves and then slice the florets at the base where they meet the stalks. You can further cut them, if you desire pieces that are smaller or of uniform size. Trim any brown coloration that may exist on the edges. Cauliflower contains phytonutrients that release odorous sulfur compounds when heated. These odors become stronger with increased cooking time. If you want to minimize odor, retain the vegetable's crisp texture, and reduce nutrient loss, cook the cauliflower for only a short time. Some phytonutrients may react with iron in cookware and cause the cauliflower to take on a brownish hue. To prevent this, add a bit of lemon juice to the water in which you blanche the cauliflower. A few quick serving ideas: Healthy sauté cauliflower with garlic, minced ginger and tamari. For cauliflower with a vivid yellow color, "healthy sauté" it briefly with a spoonful of turmeric or generous pinch of saffron. Puree cooked cauliflower, add fennel seeds and your other favorite herbs and spices and serve as soup. Because of its shape and taste, cauliflower florets make wonderful crudite for dipping in sauces. Steam until soft, then blend until smooth with cashews, water or stock, sauteed onions, garlic, mushrooms in clarified butter, season to taste with sea salt, pepper and apple cider vinegar. This makes a wonderful creamy "white sauce" for your "Mac and cheese", creamed greens or any other recipe that calls for a cream sauce. The Immune system 12 step program 12/09/2009
Specializing in Immune system disorders and Therapeuticly nurishing peoples bodies has been a challenging yet worthy ministry choice. I knew that I would never be able to exhaust this topic of health and all its tenticles into all aspects of life. To steal a popular qoute, I "stand on the shoulders of giants", when it comes to the experience and accumulated knowledge of addressing Human nutrition and immunesystem disorder. So its here that I look back and acknowledge the process, and I offer a concentrated summary of the dietary recommendations for "re-training" and supporting your immunesystem. So do yourself, and all you come in conact with, a favor this holdiay season, and start including at least one (just start with one) of these recommendations into your health regiment. 12 Steps to a healthy immunesystem Mushrooms Nutritional Profile Mushrooms are an excellent source of many minerals including selenium, copper, potassium, phosphorus, and zinc. They are also an excellent source of B vitamins including vitamin B2, pantothenic acid and niacin. In addition, crimini mushrooms are a very good source of vitamin B1, vitamin B6 , zinc, manganese and protein. Health Benefits 6 ways that mushrooms can save the world! Powerful Phytonutrients Promote Optimal Health Zinc for Optimal Immune Function Protection against Alzheimer's Disease and Age-related Cognitive Decline Mushrooms Found to be Top Food Source of Potent Antioxidant Inexpensive Button Mushrooms Rival Exotic Ones' Antioxidant Prowess 6 Ways that mushrooms can save the world... Watch this eye opening short presentation from Paul Stamets on the amazing world of fungi...you will be amazed! http://www.youtube.com/watch?v=XI5frPV58tY Powerful Phytonutrients Promote Optimal Health For the past twenty years, phytonutrients found in mushrooms have been the object of anti-cancer research. Most of this research has centered on carbohydrate-related parts of mushrooms, including their polysaccharide and beta-glucan components. In addition, most of this research has focused on the "specialty" mushrooms, including Shiitake, Maitake, and Reishi. More recently, however, the common button mushrooms, including crimini, have been shown to have anticancer properties as well. In particular, adding these mushrooms to the diet may help protect against the development of breast cancer by preventing circulating levels of estrogen in the body from becoming excessive. (Excessive estrogen, or hyperestrogenemia, has been repeatedly linked to increased risk of breast cancer). This effect appears to be accomplished through inhibition of an enzyme in the body called aromatase (estrogen synthase) that is necessary for the production of estrogen. The range of traditional nutrients found in crimini mushrooms is equally impressive. Our food ranking system showed crimini mushrooms to be an excellent source of selenium, riboflavin (vitamin B2), pantothenic acid (vitamin B5), copper, niacin (vitamin B3), potassium and phosphorus. Selenium is needed for the proper function of the antioxidant system, which works to reduce the levels of damaging free radicals in the body. Selenium is a necessary cofactor of one of the body's most important internally produced antioxidants, glutathione peroxidase, and also works with vitamin E in numerous vital antioxidant systems throughout the body. These powerful antioxidant actions make selenium helpful not only against colon cancer by protecting colon cells from cancer-causing toxins, but in decreasing asthma and arthritis symptoms and in the prevention of heart disease. In addition, selenium is involved in DNA repair, yet another way in which adequate intake of this mineral is associated with a reduced risk for cancer. Five ounces of raw crimini mushrooms provide 52.6% of the daily value (DV) for selenium. Copper is another trace mineral that may be helpful in reducing the symptoms of rheumatoid arthritis. Copper, along with manganese (yet another trace mineral for which crimini mushrooms is a very good source), is an essential cofactor of a key oxidative enzyme called superoxide dismutase. Superoxide dismutase disarms free radicals produced within the mitochondria (the energy production factories within our cells). Copper is also necessary for the activity of lysyl oxidase, an enzyme involved in cross-linking collagen and elastin, both of which provide the ground substance and flexibility in blood vessels, bones and joints. Low dietary intake of copper may also be associated with increased fecal free radical production and fecal water alkaline phosphatase activity, risk factors for colon cancer. Five ounces of raw crimini mushrooms supply 35.5% of the DV for copper and 10.0% of the DV for manganese. Crimini mushrooms are also a good source of iron, which is primarily used as part of hemoglobin, the molecule responsible for transporting and releasing oxygen throughout the body. But hemoglobin synthesis also relies on copper. Without copper, iron cannot be properly utilized in red blood cells. Fortunately, Mother Nature supplies both minerals in crimini mushrooms. Our food ranking system also showed these mushrooms to contain a variety of B complex vitamins. Crimini mushrooms qualified as an excellent source of riboflavin, pantothenic acid and niacin, as well as a very good source of thiamin, and vitamin B6, and a good source of folate, all of which are nutrients that are necessary for carbohydrate, protein and lipid metabolism. Riboflavin (vitamin B2) plays at least two important roles in the body's energy production. When active in energy production pathways, riboflavin takes the form of flavin adenine dinucleotide (FAD) or flavin mononucleotide (FMN). In these forms, riboflavin attaches to protein enzymes called flavoproteins that allow oxygen-based energy production to occur. Flavoproteins are found throughout the body, particularly in locations where oxygen-based energy production is constantly needed, such as the heart and other muscles. Riboflavin's other role in energy production is protective. The oxygen-containing molecules the body uses to produce energy can be highly reactive and can inadvertently cause damage to the mitochondria and even the cells themselves. In the mitochondria, such damage is largely prevented by a small, protein-like molecule called glutathione. Like many "antioxidant" molecules, glutathione must be constantly recycled, and it is vitamin B2 that allows this recycling to take place. (Technically, vitamin B2 is a cofactor for the enzyme glutathione reductase that reduces the oxidized form of glutathione back to its reduced version.) Riboflavin been shown to be able to reduce the frequency of migraine headaches in people who suffer from them. Five ounces of crimini mushrooms supply 40.6% of the DV for riboflavin. The B vitamin, pantothenic acid also plays an important role in the prevention of fatigue since it supports the function of the adrenal glands, particularly in times of stress. Five ounces of crimini mushrooms provide 21.3% of the DV for pantothenic acid. Niacin (vitamin B3) is helpful in reducing cholesterol levels and in preventing osteoarthritis, while vitamin B6 is needed to convert homocysteine, a dangerous molecule that can directly damage blood vessel walls, into other benign substances. At high levels, homocysteine is associated with a greatly increased risk for heart attack and stroke, so crimini mushrooms which contain 26.9% of the DV for niacin, and 8.0% of the DV for vitamin B6 are of significant benefit. Zinc for Optimal Immune Function As if the above health benefits were not enough, crimini mushrooms were also determined to be a very good source of zinc. Zinc affects many fundamental processes, perhaps the most important of which is immune function. If one mineral was singled out for its beneficial effects on the immune system, zinc would lead the pack. A cofactor in a wide variety of enzymatic reactions, zinc is critical not only to immune function, but to wound healing, and normal cell division. Zinc also helps stabilize blood sugar levels and the body's metabolic rate, is necessary for an optimal sense of smell and taste, has been shown to prevent the blood vessel damage that can occur in atherosclerosis, and may help to reduce the painful inflammation of rheumatoid arthritis. A strong immune system depends on adequate zinc levels, so the zinc in crimini mushrooms may also help to prevent illnesses such as recurrent colds and ear infections, and even some of the serious infections seen in patients with advanced or long-standing diabetes. Five ounces of crimini mushrooms provide 10.4% of the daily value for zinc. Protection against Alzheimer's Disease and Age-related Cognitive Decline Research published in the Journal of Neurology, Neurosurgery and Psychiatry suggests that regular consumption of niacin-rich foods like crimini mushrooms also provides protection against Alzheimer's disease and age-related cognitive decline. Researchers from the Chicago Health and Aging Project interviewed over 3,500 Chicago residents aged 65 or older about their diet, then tested their cognitive abilities over the following six years. Those getting the most niacin from foods (22 mg per day) were 70% less likely to have developed Alzheimer's disease than those consuming the least (about 13 mg daily), and their rate of age-related cognitive decline was significantly less. Mushrooms Found to be Top Food Source of Potent Antioxidant L-ergothioneine, a powerful antioxidant, has been discovered in mushrooms, thanks to a new analytical method capable of identifying this antioxidant in plant material. In research presented at the 2005 American Chemical Society meeting in Washington, D.C., an American research team revealed that mushrooms contain higher concentrations L-ergothioneine than either of the two dietary sources previously believed to contain the most: chicken liver and wheat germ. Testing mushrooms consumed in the U.S., the team found that shiitake, oyster, king oyster and maitake mushrooms contain the highest amounts of ergothioneine, with up to 13 mg in a 3-ounce serving. This equals forty times as much as is found in wheat germ. Of the most commonly consumed mushrooms, portabellas and criminis have the most L-ergothioneine, followed by white buttons. White buttons, the most popular of all mushrooms consumed in the U.S., contain up to 5 mg per three ounce serving-12 times as much as wheat germ and 4 times more than chicken liver. And more good news, L-ergothioneine is not destroyed when mushrooms are cooked. Inexpensive Button Mushrooms Rival Exotic Ones' Antioxidant Prowess White button mushrooms (Agaricus bisporus), although often considered a poor relation of exotic, expensive varieties like maitake and matsutake mushrooms, provide as much or even more anti-oxidant activity as their costly cousins. Researchers at the Institut National de la Recherche Agrinomique in France found that the free radical scavenging ability of the humble button mushroom was equivalent to, if not higher than, that of maitake and the matsutake mushrooms - both of which are highly prized in Japanese cuisine for their reputed ability to lower blood pressure and fight cancer. The French team also found that the body of the mushroom contained a higher concentration of anti-oxidants than the stalk. Lead researcher, Dr. Jean-Michel Savoie commented: "It can be reasonably assumed that white button mushrooms have as much, if not more, radical scavenging power as mushrooms currently touted for their health benefit. The good thing is button mushrooms are available all year round, are cheap and may be an excellent source of nutrition as part of a healthy diet." Practical Tip: You don't have to spend a lot to enjoy mushrooms' many health benefits. White button mushrooms can be found in any grocery all year round and make a delicious, inexpensive addition to salads, soups, stir fries and omelets. And don't forget stuffed mushrooms-always a favorite and classy hors d'oeuvre. Description Mushrooms are as mysteriously unique as they are delicious. While often thought of as a vegetable and prepared like one, mushrooms are actually fungi, a special type of living organism that has no roots, leaves, flowers or seeds. While they can be cultivated, they easily grow wild in many regions of the world. Button mushrooms generally look like little cartoon umbrellas, having a dense parasol-like cap attached to a stem that can be short and thick or thin and slightly curvy. There are three different types of button mushrooms-white mushrooms, crimini mushrooms and portabello mushrooms. The white mushroom is the most common type and is the cream colored mushroom that often adorns salads. The crimini mushroom, which looks just like the button but is coffee colored, actually features a more distinctive flavor. The portabello mushroom whose large size and meaty flavor make it a wonderful vegetarian entrée, is actually an overgrown crimini mushroom. The scientific name for these mushrooms is Agaricus bisporus. Crimini mushrooms are known by a variety of other names. These include cremini, baby bellas, and Portabellini. History Button mushrooms have grown wild since prehistoric times, having been consumed as food by the early hunter-gatherers. Since ancient times, mushrooms have been thought to have special powers. The Egyptians thought that they granted immortality, and since only the pharaohs were felt to be worthy of this gift, the common people were not even allowed to touch mushrooms, let alone eat them. In ancient Rome, people oftentimes referred to mushrooms as cibus diorum-food for the gods. The folklore of many cultures, including Russia, China and Mexico held that eating mushrooms could give someone superhuman strength. Although button mushrooms have been enjoyed by people around the world for millennia, it was not until the 17th century that they began to be cultivated. The first attempts at cultivation began near Paris, a city that still has hundreds of miles of underground caves and tunnels where mushrooms are grown. Cultivation of button mushrooms began in the United States in the late 19th century. Button mushrooms are grown throughout many regions of the world, especially countries in the Northern Hemisphere. The United States is one of the leading commercial producers of button mushrooms with the majority being produced in Pennsylvania. How to Select and Store Look for mushrooms that are firm, plump and clean. Those that are wrinkled or have wet slimy spots should be avoided. Since mushrooms darken as they age, choose those that are either creamy white or tan, depending upon whether you are purchasing white or Crimini mushrooms. If your recipe calls for caps only, choose mushrooms that have short stems to avoid waste. Fresh and dried button mushrooms are available throughout the year. The best way to store loose button mushrooms is to keep them in the refrigerator either placed in a loosely closed paper bag, wrapped in a damp cloth or laid out in a glass dish that is covered with a moist cloth. These methods will help them to preserve their moisture without becoming soggy and will keep them fresh for several days. Mushrooms that are purchased prepackaged can be stored in the refrigerator for up to one week in their original container. Dried mushrooms should be stored in a tightly sealed container in either the refrigerator or freezer, where they will stay fresh for six months to one year. Tips for Preparing Mushrooms: Mushrooms are so porous that if they are exposed to too much water, they will quickly absorb it and become soggy. Therefore, the best way to clean mushrooms without sacrificing their texture and taste is to clean them using minimal, if any, water. To do this, simply wipe them with a slightly damp paper towel or kitchen cloth. You could also use a mushroom brush, available at most kitchenware stores. If using the whole mushroom in a recipe, simply slice off the very bottom of the stem, which is usually a bit spongy. If your recipe only calls for the caps, gently break off the stems with your hands and discard (or save for making soup stock). Practical Tip: You don't have to spend a lot to enjoy mushrooms' many health benefits. White button mushrooms can be found in any grocery all year round and make a delicious, inexpensive addition to salads, soups, stir fries and omelets. And don't forget stuffed mushrooms-always a favorite and classy hors d'oeuvre. A Few Quick Serving Ideas: Healthy sautéed mushrooms and onions make a great side dish to meat dishes. Add finely chopped mushrooms to a pot of tomato pasta sauce. After removing the stems from mushrooms, stuff them with your favorite vegetable medley or soft cheese. Make the classic brunch favorite...the mushroom omelet. Our new Savior...Genetics? 11/30/2009
 Most mail and magazines that arrive unwanted in your mail box usually qualify as junk. (Sorry USPS, there is such a thing as "Junk Mail") And today was no exception, being its the holiday season. Being constantly inquisitive has proven a valuable trait of mine and it was helpful this day. I found a magazine titled "Fast Company" with my name on it, and I thumbed through it to find any merritt for it making it beyond the recycle bin. To my surprise I found an article about the current state of genetic research that was hailed as being the science that could unlock the power to treat diseases and free us from the aging process, as short as 10 years ago. (http://www.fastcompany.com/magazine/140/the-gene-bubble.html) So how far have we come and what was their conclusions? Don't buy any stock in genetic research, genetic based therapies or drugs and "Keep eating those greens" ! I find there is a sense among people and practitioners that "Science will save us" and "Science is Gospel", and that if we just wait long enough and give them enough funding we will be able to solve many of the problems we face. Unfortunately, the truth be told many of the contemporary problems we face, including our health epidemics, can be traced to our "cure" of other "problems". For example, many Allopathic medications that were meant to treat the symptoms of one disorder, in fact lead to other disorders that must be treated with even more medications. This has been a major problem in the Sick Care field and Bill Sardi provides some more details of this issue. (http://www.lewrockwell.com/sardi/sardi90.html) In our desperation to be rid of any suffering and make it safely to death, we've accepted the cure that is worse than the disease. This plays out on many social and personal levels... If there ever was any hope in Genome-Based treatments for disease, this article let the air out. First by giving you a better understanding of how Genome reasearch and treatments where meant to work then showing you the leading researcher companies and their achievements and status since the completion of the human genome project...which reads like a list of achievements from your 10 year highschool reunion, only with a whole lot more funding. (think Billions!) Then goes on to describe the major problems with trying to develop treatments using genetic coding. "It turns out that many dozens or even hundreds of genes each contribute to any given human attribute, and any one gene might contribute to several. Genes, in other words, turn out to work not as simple disease switches, but in impossibly complex networks." This problem gets even bigger, "For most major common diseases...specific genes are almost never asociated with more than 20%-30% increased chance of getting sick". Even more, specfic gene sequences that are identified as possibly contributing to a given disease can be "turned off" (or "On") by other genes, "Junk" DNA, RNA, their transient nature and various environmental factors such as diet, exercise, heavy metal toxicity, radiation, viruses and countless other environmental offenses. So to pinpoint and develop a treatment for any person, let alone a population, is of such an unidentifiable complexity that scientists describe this kind of research as "job security". There seems to have been a useful payoff from all this genetic research, although most don't want to hear it. "In the vast majority of cases, individual genes apparently don't influence your destiny ...any more than your behavior does." So the age old advice of Eat whole foods, mostly vegetables, do some meaningful and enjoyable physical activity, laugh alot, eliminate toxic products from your life, don't smoke or drink, will likely be the expensive high-tech answer that we were originally looking for. And I would like to submit that all these can be found from regular visits to your own garden and kitchen...for a whole lot cheaper than regular visits to your doctors office. So when we hear that someone has a "Genetic predisposition" to develop a certain disease, it seems its more sure than a death sentence and that there is nothing that we could do about it. Even sciences own research is only revealing just how little we really know and understand how the biology of life really works, yet they are willing to presume diagnosis and treatments with their patented medications. I think this is the same as placing the Doctors and scientists in the place of God. By following these well intending yet misguided prophets, we are ultimately bringing harm on ourselves. " It is better to trust in God, than to put confidence in men" (Psalm 118:8, the very heart and middle of the Bible). Ultimately God is the curegiver...we are just the caretakers. So the best way we can take care of our gift of life is to learn how our body works, and what kinds of treatments work with the way the body is designed to heal itself. It is both a curse and a blessing to have to work for our health and what supports life. The draining efforts of directly working for our food is what ultimately regenerates us. So dig in!...work the soil, learn how you are made, eat real food, cook your own real food, and share those blessing with others, because that is what will really regenerate us. For it will ultimately prove to be painful, worthless, and futile if we insist on trying provide our own salvation. | Jay's Therapeutic Chef Blog
