Soy contains a high level of special phyto (plant-based) chemicals called Isoflavones which have a chemical structure that resembles human estrogen. By mimicking human estrogen at certain sites in the body, Isoflavones provide many health benefits. Soy contains many individual isoflavones, but the most beneficial are genistein and daidzein, which have been shown to help: ? Prevent the buildup of arterial plaque, and reduce the risk of coronary heart disease and stroke. ? Reduce breast cancer by blocking the cancer-causing effects of human estrogen. ? Prevent prostate cancer by hindering cell growth. ? Relieve many menopausal symptoms (popularly used as a natural alternative to estrogen replacement therapy.) Isoflavones also play an important role in protecting and maintaining strong and healthy bones. Independent studies conducted at the University of Illinois and the University of Hong Kong concluded that consuming Soy Isoflavones can increase bone mineral content and bone density. Another study at the University of Texas suggested that they may also stimulate bone formation. In short, researchers believe that supplemental Soy Isoflavones may play an important role in preventing, and possibly even reversing, the dreaded effects of osteoporosis.
