Soy could be the solution to cure and prevent prostate cancer (PCa). Genistein, a natural substance found in soy, inhibits prostate cancer cells from metastasizing, say researchers from Northwestern University Feinberg School of Medicine. In a recent study led by Raymond Bergan, MD, 38 men with localized PCa were given genistein pills for a month before surgery. Post-surgery examinations showed a significant increase of genes that suppress cancer cells, and decreased expression of genes that enhance cancer cells. Previous studies also indicate that men who eat soy are 30 percent less likely to develop PCa. Soy comes in many forms, including tofu, edamame, and tempeh.
