Miso Soup, Soy Compound Lowers Breast Cancer Risk
 (NY, Reuters Health, 6/17/03)

Dr. Seiichiro Yamamoto of the National Cancer Center Research Institute in Tokyo, and colleagues, questioned 21,000 Japanese women about the soy and soy-containing foods in their diets. The researchers then tracked these women for 10 years, during which time 179 of the subjects developed breast cancer. When the scientists analyzed the data, they found that women who ate the most miso soup and foods rich in isoflavones were less likely to develop breast cancer than their peers who consumed smaller amounts of isoflavones. They also noted that the total amount of soy a woman ate in general was not as significant in determining her breast cancer risk as the amount of miso soup and isoflavones that she consumed.
