I have no medical degree, I have degrees in biology from Nottingham, Southbank and Goldsmiths Uni of London. Soy has benefits in the menopause and is the rare complete protein, however, most vegetable proteins are not full proteins and require amino acid supplementation. Soy does have some drawbacks, some people are sensitive to some of it's components at different dosages. It's also a mistake to attribute what works in terms of food for one racial group to another, as our bodies have different physiological triggers due to diversity and adaptation of intestines to diet. An extreme examples would be eskimo metabolism of white fat. I dont recall ever saying she shouldnt supplement her diet. I did point out the benefits of soy and vegetable protiens as opposed to meat. I also believe all women should supplement with a vitamins as our diets are often lacking in iron as well as calcium. But, according to the experts, soy is a complete protein. According to the American Association of Family Physicians... Available in a wide variety of products, soybeans are one of the few vegetarian sources of total protein containing all of the essential amino acids required in the human diet.4 Common food preparations include edamame (whole soybeans), tofu (soybean curd), soy milk, soy flour, tempeh (cooked and fermented soy), miso (fermented soybean paste), and soy sauce (Table 16,7). Refined soy components are also available as nutritional supplements in the form of isolated soy protein and as the soy-derived isoflavones genistein, daidzein, and glycitein.4,8 Soy has been a staple source of protein in Asian diets for thousands of years and received significant attention when studies showed that Asian populations have a lower risk of breast and prostate cancers.3 Studies of soy mainly focus on three areas: dietary whole soy protein intake (e.g., soybeans, tofu); isolated soy protein supplements, which are alcohol-washed to remove components; and dietary supplementation with soy isoflavones. Allergy to soy in adults is uncommon and estimated to occur in about 0.2 percent of the U.S. population.40 Anaphylaxis has been reported with soy, but is rare.40 http://www.aafp.org/afp/2009/0101/p43.html Abstract Soybeans contain all of the essential amino acids necessary for human nutrition and have been grown and harvested for thousands of years. Populations with diets high in soy protein and low in animal protein have lower risks of prostate and breast cancers than other populations. Increasing dietary whole soy protein lowers levels of total cholesterol, low-density lipoproteins, and triglycerides; may improve menopausal hot flashes; and may help maintain bone density and decrease fractures in postmenopausal women. There are not enough data to make recommendations concerning soy intake in women with a history of breast cancer. The refined soy isoflavone components, when given as supplements, have not yielded the same results as increasing dietary whole soy protein. Overall, soy is well tolerated, and because it is a complete source of protein shown to lower cholesterol, it is recommended as a dietary substitution for higher-fat animal products. http://www.ncbi.nlm.nih.gov/pubmed/19145965 Some issues around phyto oestrogens and soy, it is good for lowering cholesterol. Like I said some toxicity issues. http://www.guardian.co.uk/theobserver/2000/aug/27/life1.lifemagazine6
