Phytoestrogens are the most exciting substances found in soybeans. They exhibit powerful anti-cancer effects in hormone-related malignancies. They are similar in structure to the female hormone estrogen, but are very weak. Excessive estrogen levels have been linked as a major factor in the cause of breast, ovarian, uterine, and cervical cancer in women.
Consumption of isoflavones may help prevent hormone-related cancers. It has been repeatedly shown that isoflavones have the ability to block the uptake of estrogen by estrogen sensitive tissues, thereby acting as anti-estrogens. There is also evidence that they can block the negative effects of androgens on the prostate gland.
Genestin & Isoflavones
Of the various isoflavones found in soy, none have been studied as extensively as genistein and found to have the following benefits:
As with other isoflavones,acts as an anti-estrogen by blocking the uptake of estrogen.
Prevents cancer cell growth by inhibiting the activity of tyrosine protein kinase, and enzyme created by oncogenes.
Inhibits other enzymes involved in cancer progression.
Causes cancer cells to differentiate and change back to normal cells.
Inhibits angiogenesis- the ingrowth of capillaries stimulated by a malignant tumor.
Acts as a poweful anti-oxidant, protecting cells from free radical attack.
There is also evidence that genistein may reduce the symptoms assocciated with menopause, bone loss, hot flashes, and possibly be a replacement for estrogen supplements.
Genistein has also been shown to inhibit platelet aggregation and thrombosis and thus may be helpful in preventing strokes and heart attacks and the development of atherosclerosis. Genistein has been found to exhibit strong anti-inflammatory properties.
Daily intake of Soy-Isoflavones is recommended.
