Soy isoflavones are phytoestrogens found in soybeans. Phytoestrogens are plant-derived nonsteroidal compounds that possess estrogen-like biological activity. The hypothesis that soybean isoflavones may help relieve menopausal symptoms (such as hot flashes, emotional disturbances and compromised sexual activity) has been confirmed by recent scientific studies. Furthermore, soybean isoflavones significantly decrease the rates of breast cancer, which is thought to be relevant to their effects as phytoestrogens. Studies also point out that high consumption of soy isoflavones in the diet are implicated in inhibiting the growth of prostate cancer cells, those who eat a low-fat diet, but rich in soy proteins, have a lower incidence of prostate cancer. |
