Many women believe that soy milk is harmful to breast disease, believing that soy products contain high levels of phytoestrogens that may cause female breast cancer; women who have already suffered from breast cancer are therefore afraid to drink soy milk, fearing that it may aggravate their condition, etc. A large survey published in the latest issue of the American Journal of Clinical Nutrition has recently rejected all these claims. The study, which involved 9,514 breast cancer patients in China and the United States and followed them for an average of 7.4 years, found that the intake of soy isoflavones in soy milk not only did not cause cancer, but also helped reduce the risk of recurrence and death from breast cancer. The study found that those patients with the highest soy protein intake had a 29% lower risk of death and a 32% lower risk of breast cancer recurrence compared to those with the lowest soy protein intake. The investigative team clearly found that the intake of soy products significantly reduced the risk of breast cancer recurrence and death. In fact, research published as early as June 2008 in the Journal of Nutrition, a leading international medical journal, showed that Asian women could reduce the incidence of breast cancer by 1/3 by drinking soy milk. There are many ways to consume soy products, and by drinking about 800 to 1200 ml of soy milk per day, you can meet the standard of 30 to 50 grams of soybeans per day recommended by the Dietary Guidelines for Chinese Residents.
