They include quercetin, present in onion skins, and anthocyanins, the major commercially used group. FLAVOR ENHANCERS • One of the newest and fastest growing categories of additives; potentiators, which enhance the total seasoning effect generally without contributing any taste or odor of their own. They are effective in minute doses— in parts per million or even less. A potentiator produces no identifiable effect itself but exaggerates one's response. They alter the response of the sensory nerve endings on the tongue and in the nose.
The leaves contain mucins, silicic acid, tannin, saponin, allantoin, quercetin, and Vitamin C (see all). Externally, this plant is used to heal wounds. It is used in "organic cosmetics."

The next time you make a vegetable or bean soup or a tomato sauce, add onion skins and let them simmer to extract some of the quercetin. Remove the onion skins before eating the dish. I grow onions in my Garden of Youth. But I use so many in cooking that I buy quite a few as well. turmeric (curcuma longa). A close botanical relative of ginger, turmeric is the Indian spice that gives curry blends their yellow color. It contains a compound called curcumin that has potent anti-inflammatory action.
If you want to extract quercetin from onions, simmer whole ones (with their brown covering) in boiling water for about Vi hour. Then strain out the onions and use the water to make soup. Remove and discard the onions' covering. Chop the onions and throw them back in the pot. PINEAPPLE [ananas comosus). The area surrounding varicose veins often becomes hard and lumpy. These lumps consist of a protein called fibrin. The walls of healthy veins contain a compound, plasminogen activator, that breaks down fibrin. But when veins become varicose, they lose plasminogen activator.

Beating Cancer with Nutrition

Later in this book, you will see the synergism in creative combinations of conventional and unconventional cancer therapies, like quercetin (a bioflavonid) and heat therapy or niacin with radiation therapy. The take home lesson here is: "Just because traditional medicine has failed to develop an unconditional cure for cancer, doesn't mean that we should categorically reject all traditional approaches.
Vitamins C, E, beta-carotene, selenium, lipoic acid, lycopene, glutathione, tocotrienols, quercetin, Coenzyme Q, oligomeric proanthocyanidins from grape seed, curcumin, Ginkgo biloba, and green tea are in the ImmunoPower to provide complete protection from an entire hierarchy of antioxidants. ANTI-PRO LIFERATIVE AGENTS While most nutritionists agree on the importance of growth (proliferative) nutrients, few nutritionists respect the importance for anti-proliferative nutrients. For every force in the body, there must be an opposing force to regulate that mechanism.
Selenium, fish oil, garlic, Cat's claw, Maitake D-fraction, vitamin E succinate, vitamin K, quercetin, genistein, and bovine cartilage all may assist the cancer patient in this manner. ALTER TUMOR PROTECTIVE MECHANISMS The tumor is a well-adapted parasite, which hides from the body's immune system by generating a "stealth" coating of human chorionic gonadotropin (HCG) which provides regional immune suppression. The cancer pretends to be a fetus, which then stops the attack by the immune system.
Some of the main categories of bioflavonoids include: 0 anthocyanins; deep purple compounds found in black grapes, beets, red onions, and berries {} catechins and epigallocatechin, which are polyphenols found in apples and green tea () ellagic acid, a true anti-cancer compound found in cranberries, raspberries, and other berries, v" flavones, found in citrus fruit, red grapes and green beans 0 flavanols, such as quercetin, myricetin, found in kale, spinach, onions, apples, and black tea () flavanones, such as hesperidin and naringen found in citrus fruits of grapefruit, oranges and lemons.
Of all the nutrition factors discussed in this book, only a few, including quercetin, have shown the potential to revert a cancerous cell back to a normal healthy cell, called prodifferentiation.
Hesperidin, quercetin (also in and discussed later), pycnogenol from pine bark, and proanthocyanidins are other popular bioflavonoids. While bioflavonoids are known to be essential in the diet of insects, bioflavonoids are not yet considered essential in the human diet. Proanthocyanidins can exist in a variety of forms, including dimers, trimers, etc.. A collective group of these proanthocyanidins are known as OPC. As the science of nutrition matures, we are finding that some of the "star" nutrients of the past may be just "supporting actors" for the real star nutrients.

Foods in this group are also rich sources of flavonoids, including quercetin and kaempferol. Of all the antioxidants in fruits and vegetables, it is the flavonoids that we eat in the largest quantity, up to one gram per day. There are many flavonoid structures, and researchers in my laboratory are developing methods for measuring the evidence that flavonoids have been eaten based on their breakdown products in the urine.

C, which has anticarcinogenic properties, but also quercetin, a mutagen and possible carcinogen), and certainly both types of substances can be consumed in a single meal (NRC 1989b). Accordingly, individuals are exposed not only to mixtures of carcinogens, but also to mixtures of carcinogens and anticarcinogens. The net effect of such complex exposures is difficult to predict and is best determined empirically. Thus, although fruits and vegetables contain substances that may be carcinogenic in humans (Stolz et al.
Of particular interest are members of the flavonoid class, such as quercetin and kaempferol glycosides, which are widely distributed in foods. Others include isoflavonoids and phytoestrogens. However, unlike the nutrients, intakes of non-nutritive constituents have not been extensively studied. No quantitative exposure information is available on the anticarcinogenic non-nutritive constituents. Their numerous conjugated forms in plants have not been investigated, and estimates of exposure are further complicated because these constituents are hydrolyzed in the gut to other products.
Conversely, the most extensively studied flavonoid, quercetin, has also been reported to be a carcinogen under other conditions of feeding (Appendix A). These opposing effects on cancer are not unique to flavonoids. For example, caffeic acid, chlorogenic acid, and eugenol have been observed both to increase and to inhibit the formation of neoplasias. Observations of both positive and negative effects on health have been made for numerous other compounds in foods, such as lectins, phenolic compounds, saponins, and enzyme inhibitors (Thompson 1993).

Bioflavonoids: Citrin, hesperidin, rutin and quercetin are available in combinations from L&H or General Nutrition Centers (GNC) for $10.76 for 100 capsules. Fiavone Acetic Acid (FAA) is available through L&H and manufactured by Freeda Vitamins. Cost is $12.60 for 250 tablets. How much to take? There is clearly no one answer for everyone to this difficult question. Recommendations are usually given for well people, and even so differ widely. Many doctors will tell you not to take supplements, since you get enough vitamins through your normal "balanced" diet to suffice.

Together with the mineral calcium, it may play an important role in preventing colon and other kinds of cancer.
Another flavonoid, quercetin, derived from the common horse chestnut, is also found in many plants, including edible fruits and vegetables. It is an enzyme inhibitor. Japanese scientists found that it markedly inhibited the growth of human stomach cancer cells (8). FAA's side effects: Doctors saw uncomfortable warmth and flushes, nausea, diarrhea and visual complaints. Low blood pressure was also seen in some patients (4,9). 1. Kerr DJ, et al.

Resveratrol (which is related to another compound found in health food stores, quercetin) is found in wine at twice the level of grape juce. It is almost entirely absent from white wine (except champagne) but is found in abundance in most of the reds, especially Pinot Noir, Merlot and a German wine called Zweigeltrebe. (It is also present in peanuts.) Scientists have concluded that "resveratrol has a direct antiproliferative effect on human breast epithelial cells that is independent of the estrogen receptor status of the cells.
