Soy Isoflavone Concentrate

Soy provides isoflavones (phyto estrogens) which are plant sourced natural substances that effectively 'top up' women's hormone levels that decline during menopause.

The Japanese, who have low rates of breast and prostate cancer, consume daily 20-80 mg of genistein, a phytochemical almost entirely derived from soybeans. But in the United States, the daily dietary intake of genistein is only 1 to 5 mg.

When Japanese women move to the United States and consume the standard American diet, their risk of breast cancer increases dramatically. Previously, doctors thought that this was because of the high fat content of the western diet, but new studies fail to show a significant link between dietary fat and breast cancer risk. Some researchers now think that the increase in breast cancer results from a diet that is deficient in soy isoflavones.

Genistein and other soy components provide anticancer protection by the following mechanisms:

Blocking the cell mutating actions of pesticides, herbicides, fungicides and other pollutants by preventing their binding to estrogen-testosterone cell receptor sites in the breast and prostate.
Inhibition of the activity of tyrosine kinase, an enzyme required for most tumor cell proliferation.
Inhibition of new blood vessel growth required to feed tumors.
Inhibition of cancer cell protein synthesis.
Induction of cancer cells to differentiate into normal cells.

The following forms of cancer have been shown to respond favorably to soy adjuvant therapy:
Prostate cancer
Leukemia
Glioblastoma multiforme
Bladder cancer

Other Medical Benefits of Soy
According to published studies, the daily intake of sufficient soy isoflavones may:
Alleviate post-menopausal symptoms
Stimulate bone formation
Inhibit LDL cholesterol oxidation
Reduce total and LDL cholesterol levels
Inhibit the development or progression of atherosclerosis
Prevent gallstones
Reduce the risk of cancer at multiple sites
Protect kidney function

Disease Prevention in Postmenopausal Women
Dr. Sulistiyani of the Primate Research Center at Bogor Agricultural University in Indonesia stated that considering the increased risk of breast cancer and uterine cancer in women using estrogen drugs, one alternative is to take phytoestrogens, such as genistein, which have been shown to protect the heart against cardiovascular disease. In studies it was shown that genistein inhibited LDL (the harmful form of cholesterol) oxidation by 48%. When used in combination with vitamin E this effect was even more pronounced! In order to lower cholesterol, and especially the dangerous LDL fraction of cholesterol, it may be necessary to use one of the following soy supplements.
