In terms of health benefits, soy is one of the most studied foods around. Most of the research covers its potential for preventing cancer and heart disease. Genistein and other isoflavones (plant chemicals) in soy are being investigated for their abilities to fight these diseases.
Substituting soy protein for animal foods can lower your chances of heart disease, concluded a study published last year in the American Journal of Clinical Nutrition. And last year, a clinical trial confirmed that eating 50 g of soy protein (the amount in about two cups of soymilk) as part of a diet low in saturated fat and cholesterol can lower total cholesterol, triglycerides, and blood pressure in men and women.
