Like many endocrine disruptors, the soy isoflavones cause thyroid dysfunction in humans. . . In one UK feeding study involving premenopausal women, 6og of soy protein per day for one month disrupted the menstrual cycle and the effects of isoflavones continued for three months even after cessation of the soy diet. These effects were at dose per body-weight levels at least one order of magnitude lower than levels that soy-based formula-fed infants are exposed to.

RECOMMENDATIONS —I Experiment with changes in the diet to see if boosting levels of specific amino acids alters the intensity of sexual desire. Try eating foods that contain the amino acid L-arginine, including chocolate, almonds, peanuts, and most other nuts, or take 500 to 2,000 milligrams of supplemental L-arginine daily.

RECOMMENDATIONS LJ Use both quercetin and soy isoflavones. Studies at the Indiana University School of Medicine have found that quercetin and genistein, a key soy isoflavone, enhance each other's effects. Ll Take 200 micrograms of selenium daily. Selenium supplements are especially useful for women with ovarian cancer who are undergoing multidrug chemotherapy. LJ Avoid weight-loss diets and fasts. Although certain kinds of fat restriction reduce the risk of developing ovarian cancer, calorie restriction after the disease has developed may accelerate the disorder's progress.

Soy isoflavones could theoretically interfere with the action of oral contraceptives, although studies have not confirmed this. Soy products may impair thyroid function or reduce absorption of thyroid medication, at least in children. People with impaired thyroid function should use soy in moderation or under medical supervision. Soy Lecithin Latin name: Soy lecithin is taken from the beans of the soy plant, Glycine max (Fabaceae [legume] family) GENERAL DESCRIPTION Soy lecithin, like soy isoflavone concentrate, is an extract of the soybean.

Although it is not a purely herbal product, ipriflavone, a chemically altered form of soy isoflavones, is a better choice for preventing and treating osteoporosis, and for preventing bone fractures in weight lifters and participants in contact sports. Clinical testing in Japan has found that treatment with ipriflavone, even without supplemental calcium, prevents bone loss better than calcium supplementation alone. Brands that provide ipriflavone in a corn-oil base may be better absorbed.

Soy isoflavones are also found in the herb kudzu. (See kudzu under The Herbs in Part One.) Of readily available soy foods, roasted soybeans have the highest isoflavone content, about 167 milligrams for a 3.5-ounce serving. Tempeh is next, with 60 milligrams, followed by soy flour with 44 milligrams. Processed soy products such as soy protein and soymilk contain about 20 milligrams per serving. Although the optimum dosage of isoflavones obtained from food is not known, one study found that ingesting 62 milligrams of isoflavones daily is sufficient to reduce cholesterol.

Ir was the toxicity of dietary levels of isoflavones in animals that first raised the awareness of the scientific community to the fact that soy isoflavones were endocrine disruptors. Reproductive effects, infertility, thyroid disease or liver disease due to dietary intake of isoflavones had been observed for several animals including cheetah, quail, mice, rats, sturgeon, and sheep.46 Soy Foods Block the Absorption of Brain-Essential Minerals Unfermented soy products contain another natural protein that makes soy-based formulas hazardous to your baby's health: phytic acid.

Natural food stores and supermarkets now carry a wide variety of soy products, from chocolate soymilk and barbecued tempeh burgers to Thai peanut tofu and soy sausages. soy isoflavones are also available in capsule form and in some supplements for bone health. In general, you will find lower amounts of isoflavones in processed soy foods containing soy protein isolate and concentrate, although such foods are usually high in soy protein. These foods include many brands of veggie burgers, meatless dinner entrees, chicken-free nuggets, soy "ice creams," and energy bars.

Although research on soy and osteoporosis is still in its early stages, one clinical trial showed that 66 postmenopausal women consuming a diet high in soy isoflavones had significant increases in bone mineral content and density in their lumbar spines after 6 months, compared with a control group.10 This is supported by an animal study which showed that soy helps prevent bone loss associated with estrogen deficiency.11 Other areas of current research include a potential role for soy in treating diabetes, kidney disease, and autoimmune diseases.

Soy also affects heart disease risk in ways other than reducing blood cholesterol: soy isoflavones prevent and reverse the formation of plaque deposits on artery walls. Since Sirtori's study was published, more than two dozen clinical studies have clearly demonstrated that substituting soy protein for animal protein or simply adding soy protein to the diet significantly reduces blood cholesterol levels, regardless of the type or amount of fat in the diet.

When estrogen levels are low, research shows that the soy isoflavones genistein and daidzein bind to estrogen receptors in the body. It is likely that this accounts for many of soy's effects on menopause-related problems.24 In a recent laboratory study, researchers tested 150 herbs and found that soy was one of the top seven estrogen receptor-binding plants, along with red clover, licorice, hops, thyme, turmeric, and verbena.25 Currently, there is no evidence to suggest that soy's isoflavone content increases the risk of developing estrogen-dependent cancers.

I'd like you to set a goal of consuming enough soy products, including soy meat replacers, soy foods such as tofu, soy milk, and soy cocktails to obtain between 40 and 80 milligrams of soy isoflavones. This level of isoflavone intake should provide for optimum breast cancer protection. Use Table 5.4 to reach this goal each day.

Some scientists have proposed that soy isoflavones act as estrogen antagonists, protecting against more harmful forms of estrogen by competing with them at receptor sites. This would give soy an action similar to that of Tamoxifen, a drug that fights breast cancer by interfering with estrogen binding at receptor sites. However, current evidence suggests that this may not be the way soy works.24 It is likely that genistein and other constituents from soy protect against breast cancer in different ways, depending on when they are administered.

Mike Fitzpatrick of New Zealand lists health concerns regarding soy-based infant formulas: The potential for biological effects in infants due to the soy isoflavones has been clearly identified and includes changes in the function of sex glands, the central nervous system, the thyroid, and behavioural patterns. Exposure of infants fed soy-based formulas to isoflavones is high, greater than iooo times that found for infants fed on breast-milk or cow's-milk based formula.

Animal research suggests that naringenin may have anticancer activity.2 soy isoflavones are also currently being studied to see if they help fight cancer. Where Are They Found? Bioflavonoids are found in a wide range of foods. For example, flavanones are in citrus, isoflavones in soy products, anthocyanins in wine and bilberry, flavans in apples and tea, etc. Who Is Likely to Be Deficient? Bioflavonoid deficiencies have not been reported. How Much Is Usually Taken? Bioflavonoid supplements are not required to prevent deficiencies in individuals eating a healthy diet.

Because soy isoflavones are a thousand times weaker than estradiol, they don't have the deadly effect of estradiol made by the body. The most widely used drug in breast-cancer treatment, tamoxifen, works in a similar way. Asian women, whose diets are rich in soy, normally have lower estradiol levels than American women and enjoy half the rate of breast cancer and fewer symptoms of menopause. Soy is so effective at regulating estradiol levels that far fewer Japanese women than American women suffer from premenstrual syndrome (PMS)—a condition caused by fluctuating hormone levels.

Breast cancer. soy isoflavones and phytosterols first came to American scientific attention at a National Cancer Institute conference in 1990. Isoflavones, also known as phytoestrogens (literally, plant estrogens) show the most powerful anti-cancer effects. They are structurally similar to the female sex hormone, and they bind to the same receptor sites on breast cells. But unlike hormonal estrogen, isoflavones and phytosterols do not spur the growth of breast tumors.

Though the supplements aren't so good a source as food, this may be the most practical way to increase intake of soy isoflavones (although the least-studied). Supplements are available in 50-milligram capsules, and the usual dosage is 50 to 150 milligrams daily. Look for foods and supplements that are nongmo (meaning they are not seneticallv ensineeredV Also, look for sov nrorhicts that list the isoflavone content Not all of them do. (For example, some soy protein isolates have had the isoflavones removed by alcohol extraction.

This is thought to be a good thing. soy isoflavones may block strong or toxic estrogens from binding to receptor sites on hormone-dependent tissues such as the breast, uterus, and prostate. By occupying these sites and effectively taking the place of the more powerful forms, the phytoestrogens help prevent cancer growth. Isoflavones, which are available in supplement form as well as in foods, are key compounds in decreasing cholesterol levels. DOSAGE Fermented soy foods should be eaten liberally for their health-protective qualities. Next best?

Geni-stein is the most studied of the soy isoflavones with regard to antioxidant activity. It is thought that genistein may be a more potent antioxidant than daidzein. There are few studies comparing the antioxidant activity of the two isoflavones. The proposed mechanism of daidzein's possible antidipsotropic activity is as follows. Daidzein inhibits the class I isoenzymes of human alcohol dehydrogenase (ADH), especially the gamma-type ADH. Inhibition of human class I ADH may suppress ethanol consumption by increasing the bioavailability of ingested ethanol.

The mild estrogen activity of soy isoflavones may ease menopause (p. 118) symptoms for some women, without creating estrogen-related problems. A group of 58 menopausal women, who experienced an average of 14 hot flashes per week, supplemented their diets with either wheat flour or soy flour every day for 3 months; the women taking the soy reduced their hot flashes by 40%.7 In one double-blind trial, 60 grams of soy protein led to a 33% decrease in the number of hot flashes after 4 weeks and a 45% reduction after 12 weeks.
