The Food and Drug Administration has indicated that eating 25 grams of soy protein daily helps to reduce your risk of inflammation-driven cardiovascular disease. But according to two 2009 studies, even as little as half that may be helpful. “We saw a reduction in inflammation after drinking just two [12-ounce] glasses of soymilk a day for three months,” says study co-author Elvira de Mejia, Ph.D., associate professor of nutrition at the University of Illinois at Urbana. (Each glass contained 6 grams of soy protein.) Apparently, lunasin, a peptide found in soymilk and tofu, in combination with other soy proteins, can quell inflammation. (If you have a hormone-sensitive condition, such as breast cancer or endometriosis, check with your doctor before increasing the amount of soy in your diet.)
