I believe that everyone should take a broad-spectrum vitamin/mineral supplement with antioxidants, including alpha and beta carotene, vitamins c, E, selenium, and glutathione, an amino acid. In addition, depending on your age, sex, personal medical history, and genetics you may want to add particular supplements that may help prevent specific types of cancer. Prostate Cancer Prostate cancer is the second most common cancer in men (skin cancer is number one), and is of great concern because it appears to be increasing.

Besides this, the tea's polyphenols act in concert with the vitamins c and P present to help strengthen the blood vessel walls of the heart more. Tea Removes Dental Plaque During 1983-84 dental scientists at Washington University in St. Louis conducted a series of experiments proving that black tea definitely inhibits the growth of decay-causing bacteria common to plaque buildup on the teeth. This is probably due to the high natural fluoride content found in both teas.

An ingredient, epigallocatechin gal-late (EGCG), reported carries twice the antioxidant power of red wine and vitamins c and E. See Antioxidants. GROUND LIMESTONE • Used as a flavoring. GRAS. GROUNDSEL EXTRACT • Extract of Senecio vulgaris, a North American maritime shrub or tree. GUAIAC • A resin from Mexican and West Indian trees, especially Guaiacum santum and Guaiacum officinale. Brownish lumps that are insoluble in water but soluble in alcohol. Used as a flavoring in alcoholic beverages only. See Guaiac Wood Oil.

Until the all-purpose agent comes along or until consumer preference changes, the best compromise probably will be continued use of nitrite in conventional amounts with vitamins c and E added to block formation of nitrosamines, or the use of smaller amounts of nitrite in combination with biological acidification, irradiation, or the chemicals potassium sorbate, sodium hypophosphite, or fumarate esters, the Committee said. To reduce nitrosamines in bacon, the U.S. Department of Agriculture requires meat packers to add sodium ascorbate or sodium erythorbate (vitamin C) to the curing brine.

Fat-soluble antioxidants, beta-carotene and other carotenoids, as well as vitamins c and E and pycnogenol (see), are believed to fight the damage from free radicals. FRESH • A food that has not been heat processed or frozen and supposedly contains no preservatives. FRUCTOOLIGOSACCHARIDES (FOS) • Sugars that occur naturally in plants such as tomatoes, onions, and bananas. They are not digestible in the stomach and travel unabsorbed to the intestine. In the intestines they promote the growth of beneficial bacteria such as those used to culture yogurt.

The berries contain isocitric and malic acids, sugars, pectin, monoglycoside of cyani-din, vitamins c and A. The leaves and bark are said to lower fever, are astringent, and stop bleeding. The leaves are used for a soothing bath. BLACKTHORN BERRIES • See Sloe Berries. BLEACHING AGENTS • Used by many industries, particularly flour milling, to make dough rise faster. Certain chemical qualities, which pastry chefs call "gluten characteristics," are needed to make an elastic, stable dough.

So might the actions of the National Academies' Food and Nutrition Board (FNB) in recommending higher levels of intake of vitamins c and E when the board's work is funded in part through a foundation supported by companies such as Roche Vitamins, Mead Johnson Nutrition Group, Daiichi Fine Chemicals, Weider Nutrition Group, and the Natural Choice Vitamin E Association—all with vested interests in having nutrient standards set so high that people can meet them only by taking supplements. The FNB itself is supported directly by food and supplement companies such as G.D.

Most of the antioxidant defense systems have their origins in dietary vitamins and minerals, including beta-carotene, vitamins c and E, selenium, zinc, copper and manganese. It is essential that intake of these micronutri-ents is adequate in a cardioprotective formula. The Formula 1) Review and follow the Formula for Cholesterol Control, which includes specifics on diet, exercise and use of supplements. 2) Include garlic, onions and hot chili peppers in your diet. As with exercise, if you have never used these food items, you need to add them gradually to your diet.

About 20,000-30,000 IUs daily, preferably as beta-carotene, may be the best range, especially for those of us with some levels of anxiety and stress. If vitamins c and E are used, slighdy lower amounts of A are needed, since C and E help prevent the loss of stored vitamin A. The upper intake, including diet and supplemental vitamin A, ranges from 50,000-100,000 IUs per day for short periods of a week or two. However, these amounts often produce some side effects over time. If no body deficiency or increased body needs of vitamin A are present, 50,000 IUs can cause problems.

They concluded that vitamin E consumption had a significant protective effect against oral cancer, and vitamins c and E had a protective effect against esophageal cancer. Osteoporosis. The FDA already allows the manufacturers of calcium supplements to claim benefits in preventing osteoporosis. Magnesium also helps, according to Israeli researchers who gave women past the age of menopause 250 to 750 milligrams of the mineral daily for two years. Compared with untreated women, whose bone density declined 1 to 3 percent, bone density in the magnesium group increased 1 to 8 percent.

Danish researchers found that ten days of supplementation with the antioxidant vitamins c and E reduced oxidative lung damage to smokers' lungs by about 50 percent. Tinnitus. Tinnitus, chronic ringing in the ears, is a frustrating condition that doctors have difficulty treating. At the Institute for Noise Hazards Research in Ramat-Gan, Israel, researchers compared people with tinnitus and other forms of hearing impairment. Those with tinnitus were significantly more likely to show low blood levels of vitamin B12. Bn supplementation provided some tinnitus relief for several people in the study.

It is also high in B vitamins and vitamins c and D, and it is a good source of calcium, iron, potassium, iodine, and many trace elements. Nori reduces vata. Use Sheets of nori are used to wrap sushi and rice balls; they can be cut or torn and used as a garnish or in soups. Nori may be used as is or lightly toasted by slowly waving it over an open flame or the burner of an electric stove. It has a tasty, delicate, nutlike flavor. Nori flakes can be sprinkled over salads, popcorn, grains, and vegetable dishes. Buying The price of nori varies greatly and directly reflects quality.

High in vitamins c and A, and in potassium, rhubarb also contains tannin, the astringent substance responsible for making your mouth pucker up. Use Trim off the dried stalk ends of the rhubarb, coarsely chop, sweeten to taste, and stew or boil until tender, 10 to 15 minutes. To be edible, this tart vegetable, which is used like a fruit, demands ample added sweetener. Cook it in a nonreactive (stainless steel or glass) pan. Rhubarb is eaten as a compote and is used in pies, dessert sauces, and jams.

It is an excellent source of vitamins c and K and potassium. Use Atemoyas are used in fruit salads or can be riced and served as a fruit sauce. They're also eaten out of the rind, one spoonful at a time. Buying/Storing This delicac is available in the fall. Select thin-skinned atemoyas that are somewhat tender and unblemished. Allow to ripen at room temperature until they are soft, then consume immediately or refrigerate for a few days. Do not refrigerate until the fruit is ripened. Upon ripening, it may split at the stem end. See Tropical Fruit. Atole See Pinole. Aubergine See Eggplant.

Watermelon is a good source of vitamins c and A and potassium. It is low in sodium and calories and has no fat. Use Watermelon flesh is enjoyed in fruit salads, in fruit punch, and just by itself. Its seeds may be seasoned, toasted, and eaten as a snack food like squash or pumpkin seeds; and its rind (both the green skin and the white layer) makes a delicious pickle. To make watermelon juice, remove the seeds and process the flesh in a blender or processor to create a uniform pulp, which may be diluted with water or another juice and seasoned to taste.

It may help maintain levels of some other antioxidants, principally vitamins c and E. Many of these effects have only been demonstrated in vitro. In one of the few clinical trials of pycnogenol, the substance significantly inhibited smoking-induced platelet aggregation, more significantly with doses of 200 mg than with doses of 100 or 150 mg of pycnogenol. A single 200 mg dose of pycnogenol was reported to significantly inhibit platelet aggregation for longer than three days in smokers.

Animal model work has produced preliminary evidence that NAC, apparently more than either vitamins c or E, or both, can be of some benefit in insulin-dependent diabetes mellitus. NAC reportedly inhibits pancreatic beta-cell apophysis without affecting the rate of beta-cell proliferation. NAC has also been shown to moderately decrease blood glucose levels and to retain glucose-stimulated insulin secretion. There is some interest in NAC as a possible anti-cancer agent. There is some preliminary work indicating that it might be helpful in the early stages of some cancers.

But other rats first given a combination of vitamins c and B, along with cysteine, and then exposed to the same dose of acetaldehyde, all survived. Cysteine's protective mechanisms could relate to its own antioxidant properties, its promotion of glutathione (a major antioxidant) or even, it has been hypothesized, to some ability to participate in DNA repair. There is inconclusive evidence that cysteine could play a positive role in the treatment of osteoarthritis and rheumatoid arthritis.

A retrospective study of a nutritional supplement called ICAPS Plus (which contains beta-carotene, vitamins c and E, zinc, copper, manganese, selenium, and riboflavin) compared the 38 who used the preparation regularly with the 37 who used only one bottle, who served as controls. Fifteen of the treated patients improved their vision by one line or more compared with only six of the control group. In addition, three of the 38 in the treatment group lost one line or more of vision, compared with 13 in the control group.

Other nutritional qualities of the fruit and vegetable fiber foods seem to help inhibit cancer formation as well. vitamins c and E, beta-carotene, and selenium, plus the plant sterols and antioxidant phenolic compounds like bioflavonoids from foods such as berries and citrus fruits, all seem to be beneficial factors. The cruciferous vegetables, such as broccoli and cabbage, seem to have other factors such as sulfhydryl-containing molecules besides the fiber that may protect against the development of cancer. Cancer of the breast and a high-fat diet have been shown to be related for some time.

Cobalamin, along with iron, folic acid, copper, protein, and vitamins c and B6, is needed for the formation of normal red blood cells. Vitamin B12 is the "energy" vitamin, as it often increases the energy level, whether obtained from eating the B12 foods or from supplemental use. There may be several reasons for this. Cobalamin stimulates the utilization of proteins, fats, and carbohydrates. It also helps iron function better in humans and is important for the synthesis of DNA and RNA, as well as for production of choline, another B vitamin, and methionine, an amino acid.

The antioxidant activity of curcumin is comparable to standard antioxidants like vitamins c and E, and butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT).3,7 Because of its bright yellow color and antioxidant properties against lipid peroxidation, curcumin is used in butter, margarine, cheese, and other food products. For active oxygen species, curcumin is slightly weaker than vitamin C, but stronger than vitamin E and superoxide dismutase. Against hydroxyl radicals, curcumin offers greater effectiveness than these vitamins.

Since PCOs have a greater antioxidant effect than vitamins c and E, it is only natural to speculate they could offer greater protective effects. Support exists for this contention. For example, several studies have shown the protective effects of red wine against heart disease and stroke by protecting against LDL oxidation.18 The active components in the wine are thought to be proanthocyanidins. Also, a recent study of 805 men beginning in 1985 demonstrated an inverse correlation between flavonoid intake and death due to heart attack.

Vitamin A and beta-carotene, vitamins c and E, glutathione, and selenium are all important antioxidants that help protect us from disease. For example, a recent study revealed, that smokers who were low in beta-carotene had an increased lung cancer rate than those with higher or supplemented levels. Cigarette smoke is a complex mixture including chemical carcinogens known to everyone. Although exposure to cigarette smoke does not invariably cause cancer, it is irritating to everyone.

A tremendous amount of scientific research indicates that the "optimal" level for many nutrients, especially the so-called antioxidant nutrients such as vitamins c and E, beta-carotene, and selenium, may be much higher than their current RDA. The RDAs focus only on the prevention of nutritional deficiencies in population groups; they do not define "optimal" intake for an individual. Other factors the RDAs do not adequately take into consideration are environmental and lifestyle factors which can destroy vitamins and bind minerals.

However, the antioxidant activity of flavonoids is generally more potent and effective against a broader range of oxidants than traditional antioxidant nutrients like vitamins c and E, selenium, and zinc.2,3 Because different flavonoids tend to provide different benefits, additional and more specific beneficial effects are discussed under the three selected categories. There is significant overlap among these flavonoids, however. Quercetin Quercetin consistently demonstrates the greatest activity among the flavonoids studied in experimental models, particularly in vitro studies.
