A recent study found that soy foods lower women’s risk of breast cancer. The study reviewed food intake questionnaires from 70,578 Chinese women, 40-70 years of age, participating in the Shanghai Women’s Health Study.
This study’s results are in line with previous research demonstrating that soy foods lower a woman’s risk of developing breast cancer. The greatest benefit appears to be in premenopausal women. Among women who developed breast cancer during the study period, soy foods appeared to delay the onset by 2-5 years.
