Recent data shows that children consume 40 milligrams of soy isoflavone per day with an adult consumption range of 150-200 milligrams per day. This study suggests that these levels are safe and effective. More importantly, cells exposed to genistein demonstrated decreased invasion capacity in vitro. Genistein is currently undergoing clinical studies in the treatment of breast cancer and warrants further study in the treatment of endometrial cancer. Uncontrolled, high estrogen levels in a woman's body have been linked to endometrial difficulties like PMS, fibroids and endometriosis.
Soy protein can balance high estrogen levels.
Studies show that women who consume soy protein significantly lower their estrogen levels to much healthier levels. Daily consumption for 3 to 6 months is typically required to start seeing these benefits. In summary, we will continue to see more exciting research on soy and endometrial health in the near future. Since soy may work to reduce cancer risk through many different mechanisms, consuming whole soy protein products that contain all of the beneficial soy phytonutrients is important. The FDA, American Heart Association, and North American Menopause Society recommend that Americans eat more soy protein to lower their cholesterol, protect their hearts, and reduce menopausal symptoms.
