Generous consumption of soy foods may help stave off breast cancer.
This study examined the influence of high dietary ingestion of soy foods on the incidence of breast cancer in Chinese women. Data from 300,000 women, of whom 2,289 eventually developed breast cancer, were analyzed to estimate the risk of breast cancer according to the frequency of consumption of soy foods.
Researchers noted that as the rate of soy foods increased, the risk of breast cancer declined. Daily consumers of additional 10 mg of isoflavones from soy foods enjoyed a 3% reduction in the risk of breast cancer. The data from this study support the conclusion that high intake of soy foods may help combat the development of breast cancer.
