For example, triterpenoids may inhibit the action of estrogens, which promote cancers of the breast and uterus. flavonoids, found in many higher plants, appear to inhibit how carcinogens interact with DNA. Because of this, it is possible they could disarm cancer-causing chemicals that form during the cooking of meat or fish (see Chapter 22, "The ABCs of Staying Healthy"). Dietary Recommendations In 1982, the Committee on Diet, Nutrition and Cancer of the National Research Council (NRC) released its landmark study on the relationship between diet and cancer.

Dietary antioxidants of extreme significance in life-extension include vitamins C and E, selenium, beta-carotene, flavonoids, sulfur-containing amino acids, and coenzyme Q10. Not surprisingly, these same nutrients are also of extreme significance in cancer prevention, as aging and cancer share many common mechanisms. Perhaps the most important dietary antioxidants for longevity are carotene molecules. Carotenes represent the most widespread group of naturally occurring pigments in plant life.

Dietary factors that enhance immune function include all essential nutrients, antioxidants, carotenes, and flavonoids. Consistent with good health, optimal immune function requires a healthy diet that (1) is rich in whole, natural foods, such as fruits, vegetables, grains, beans, seeds, and nuts, (2) is low in fats and refined sugars, and (3) contains adequate, but not excessive, amounts of protein. On top of this, individuals are encouraged to drink five or six 8-ounce glasses of water per day (preferably pure water).

Double-blind, placebo-controlled studies have shown that supplemental citrus flavonoids cut in half the time needed to recover from sports injuries.4,5 Vitamin B12 An uncontrolled study found that intramuscular injections of vitamin B12 (daily for the first week and then less frequently according to response) gave rapid relief from bursitis pain for most patients. Subsequent X rays of patients with bursitis that had formed calcium deposits showed considerable breaking down of the calcium deposits.

The furanochromones such as khellin from Ammi visnaga are structural derivatives of benzo-gamma-pyrone (furanobenzo-gamma-pyrones) and therefore are as much related to flavonoids as coumarins. In other words, the carbonyl group is opposite the oxygen rather than adjacent to it. However, they are usually classified as coumarins and will be considered in this section. Ammi visnaga also contains visnadin, a pyranocoumarin. The widespread nature of coumarins means that they are consumed in human diet, for example, carrots, celery and parsnip.

Anxiolytic properties have been demonstrated for some flavonoids (chrysin and api-genin) which selectively bind with high affinity to the central benzodiazepine receptor.110 The relationship between dietary flavonoid intake and cardiovascular disease has been tested in several epidemiological studies. The Zutphen Study in Holland found that flavonoid intake in elderly men (largely via tea, onions and apples) was significantly inversely associated with mortality and incidence of stroke.

In a multicentre, double-blind comparative study, 132 patients with NYHA stage II stable heart disease were treated with 900 mg of concentrated hawthorn extract (3:1, standardized to 2.2% flavonoids) or 37.5 mg captopril for 8 weeks. None of the measured parameters (exercise tolerance, pressure-rate product and five typical symptoms) showed any significant difference between the two treatments. One patient treated with captopril had to discontinue therapy due to adverse effects; no patients withdrew from the hawthorn treatment.

The total flavonoids from hawthorn have a phosphodiesterase inhibitory activity in vitro.27 Hawthorn extract exhibited a positive inotropic effect on the contraction amplitude accompanied by a moderate increase of energy turnover in cardiac myocytes in vitro. In comparison with other positive inotropic procedures, the effects of hawthorn extract were significantly more economical with respect to the energetics of the myocytes. Hawthorn also prolonged the apparent refractory period in the presence and absence of isoprenaline (beta-adrenergic agonist), indicating an antiarrhythmic potential.

Choose a high-potency vitamin C with flavonoids and take 1,000 mg 2 times a day. Also, cook acidic foods such as tomatoes and applesauce in cast-iron pots to leach the iron from the pot into the food. Women with a profuse flow usually need vitamin A-rich foods, and should be eating some of the following each day: carrots, yams, sweet potatoes, spinach, cantaloupe, broccoli, and kale. Other antioxidant supplements are B12 and vitamin E, which may also reduce endometrial bleeding by modifying free radical activity and prostaglandin action.

Flavonoids are of particular benefit in treating RA due to their neutralization of inflammation and support of collagen structures.59 In short, the antioxidant benefits of fresh fruits and vegetables go well beyond the antioxidant effects of vitamins and minerals. Several studies have shown that the risk of RA is highest among people with the lowest levels of nutrient antioxidants (e.g., serum concentrations of vitamin E, beta-carotene, and vitamin C).

As it turns out, grape juice contains some of the same flavonoids that are found in wine. Studies suggest that these compounds may help lower cholesterol, prevent cholesterol from sticking to artery walls, and keep blood platelets from sticking together and forming dangerous clots in the bloodstream. Great Grapes Scientists are still unraveling the mysteries of how grape juice helps protect against heart disease. One thing they do know is that it appears to help in more than one way.

Leave as much of the white, pithy part as possible, though, since it's loaded with vitamin C and flavonoids. • Cut fruits and vegetables into small-enough pieces to fit easily through your juicer. Cut off and discard any parts that look bruised or damaged; they don't add any nutritional value and may affect the taste of your juice. • Wash and juice any stems or greens that are still attached to the fruit or vegetable. Many, such as beet greens, are rich in valuable minerals. Two exceptions are carrot and rhubarb greens, which can be toxic.

A five-year Dutch study of 805 elderly men found that those who regularly consumed fruits and vegetables high in flavonoids were less likely to die of heart disease than those whose intakes were lower, regardless of their intakes of other nutrients. Raw fruits and vegetables are also rich in enzymes, substances produced in plant tissue that kick off the many chemical reactions necessary for human digestion. "Natural foods come 'packaged' with just the right enzymes to help us digest them," says Blauer.

Have a piece of orange or some strawberries, and you'll consume flavonoids that prevent cancer-causing hormones from latching on to a cell, says Dr. Pierson. Have some green pepper or pineapple, and you'll get p-courmaric acid and chlorogenic acid, substances that stop cancer cells from forming. Have a slice of tomato, and you'll get up to several hundred different phytochemicals, most of which seem to play some role in stopping tumors before they form.

Similar flavonoids that improve liver function are also found in rosemary and grape leaves, which are used in Greek cooking. All of these herbs protect the liver from damage and increase the production of beneficial liver enzymes so that the liver can do its job better. One important function of antioxidants is to protect the liver against damage from heavy metals and other toxic substances in the air and the food we eat.

In addition, the enzyme bromelain from pineapple and the flavonoids known as anthocyanidins, which come from bilberry and other dark fruits, not only keep blood clots from forming, but also break down plaques of cholesterol that have already formed inside the arteries. Bromelain, evening primrose oil and anthocyanidins are usually available only as pills, but you can buy the other herbs in a variety of forms. You can also get anthocyanidins into your system by taking pills that contain bilberry or other herbs that are high in these compounds.

Flavonoids are compounds found in plants. They have antioxidant and antiinflammatory effects. 19. We bought some bags that are supposed to keep our fruits and vegetables from rotting as fast. From what chemical is this bag made and how does it work? These green plastic-like bags are made from oya, a natural mineral that absorbs ethylene gas. The gas causes the rotting. 20. What is the chemical in those little birthday cake candles that reignite after you blow them out? They have magnesium crystals in them, which retain the heat even after the flame is out.

These flavonoids are credited with reducing stroke and heart disease and improving the immune system to effectively fight viruses. Cosmetics 1. What does the FDA state that a cosmetic can claim? A cosmetic can claim four things. It can cleanse, beautify, promote attractiveness, and alter the appearance in general. 2. What type of claims can be made for drugs? A product that makes structural and functional claims can be classified as a drug. For instance, a product that penetrates the skin and causes cell rejuvenation has legitimate claims as a drug. 3.
