Researchers are look-ing into it.
One of today's hottest research topics is phytoestrogens. Produced by both men and women, estrogen can be harmful in certain circumstances and protective in others. Scientists believe phyto-estrogens may work to prevent these problems by binding to cell receptors in the body that would otherwise attract the body's own estrogen, which is far more potent. Because the plant compounds seem so promising, many people are adding phytoestrogen-rich foods to their diets. We'll know more in 10 years.
