  • Isoflavones are members of the large flavonoid family of plant compounds, which are in turn members of the larger group of plant constituents known as polyphenols. The principle isoflavones in soy are genistein, daidzein, and their metabolites.
  • Isoflavones are a subclass of a larger and more ubiquitous group of nutraceuticals called flavonoids. In comparison to most flavonoids, isoflavones have a very limited distribution in the plant kingdom. While flavonoids are found in many plant foods such as onions, apples, and grapes, soybeans are the only food to contain nutritionally relevant amounts of isoflavones.
  • In soybeans and nonfermented soyfoods, isoflavones are present primarily as beta-glucosides, esterified with malonic or acetic acid. In fermented soy products such as tempeh and miso, due to microorganism-induced fermentation and hydrolysis more of the isoflavones are present in aglycone (unconjugated) form. Isoflavones are quite heat stable. Baking or frying does not alter total isoflavone content and although the chemical structure of the isoflavone is very slightly changed, this change is not thought to be nutritional relevant.
  • Isoflavones have a strikingly similar chemical structure to mammalian estrogens. Therefore, it is not surprising that isoflavones bind to estrogen receptors and affect estrogen-regulated gene products. Although isoflavones possess estrogenic and possibly antiestrogenic activity,37 the physiological effects of isoflavones, especially genistein, are likely only partially related to direct interaction with or binding to estrogen receptors.
  • Isoflavones are present in relatively large amounts in virtually all soy products, with the exception of soy-protein concentrate. Whole soy contain about 200 mg isoflavones per 100g. Soybeans contain three types of isoflavones in four chemical structures.
  • Isoflavones are widely believed to have beneficial effects on human health. This view stems mainly from epidemiological data, indicating an inverse correlation between levels of soy-derived food consumption and the incidence of certain types of cancer. Similar data support the general belief that soy consumption at the level characteristic of Asian society prevents cardiovascular ailments and post-menopausal effects, including osteoporosis.
  • Isoflavones are secondary metabolites of higher plants arising from the
    malonate–shikimate biosynthetic pathway, which produces great variety of phenylpropanoid aglycones. Two kinds of post-translational modification are characteristic of this group of natural products – O- (and occasionally C-) glycosylation and esterification by biogenic carboxylic acids.
  • Isoflavone-containing soybeans are among the most important agri-cultural crops, a traditional source of food in Asian countries, and an im-portant source of food additives and modifiers used throughout the world (e.g. in the manufacture of meat products). Because isoflavones are clearly estrogenic, among other distinct biological activity, and tons of them end up in food and animal feed, they should be traced as a matter of basic toxicological and environmental protection.
  • Soy isoflavone products are marketed as dietary oestrogens to women over the age of 50 as a natural alternative to hormone replacement therapy (HRT), but since this is also the age group in which most breast cancers occur, these new findings - if supported - could have widespread implications.
  • Soy Isoflavones help in the preservation of the bone substance and fight osteoporosis. This is the reason why people in China and Japan very rarely have osteoporosis, despite their low consumption of dairy products, whereas in Europe and North America the contrary happens. Unlike estrogen, which helps prevent the destruction of bone, evidence suggests that isoflavones may also assist in creating new bone. Other studies are not entirely consistent, but evidence suggests that genistein and other soy isoflavones can help prevent osteoporosis.
  • Isoflavones seem to be protect agains tumors because thet act against cancer cells in a way similar to many common cancer-treating drugs. Population-based studies show a strong association between consumption of isoflavones and a reduced risk of breast and endometrial cancer.
  • The North American Menopause Society suggests that soy isoflavones can also be a natural alternative to estrogen replacement therapy for relief of mild menopausal symptoms. It may help offset the drop in estrogen and regulate its fluctuations that occur at menopause. Many women have reported a reduction in their hot flashes and night sweats when they regularly consume soy foods, like tempeh or tofu.
