Tofu Takeaway: Isoflavones Lower Risk of Heart Disease

Observational research published in Circulation, the flagship journal of the American Heart Association, states that tofu and other foods that contain higher amounts of isoflavones are associated with a moderately lower risk of heart disease, especially for younger women and postmenopausal women not taking hormones. Researchers at Harvard Medical Schools’ Brigham and Women’s Hospital analyzed data from more than 200,000 people that participated in three health and nutrition studies; all participants were free of cancer and heart disease when the studies began. Consuming tofu, which is high in isoflavones, more than once a week was associated with an 18 percent lower risk of heart disease, compared to a 12 percent lower risk for those that ate tofu less than once per month. Tofu and whole soybeans are rich sources of isoflavones. Chickpeas, fava beans, pistachios, peanuts and other fruits and nuts are also high in isoflavones.
