The American Heart Association recently concluded that 25-50 grams of soy a day can help lower levels of LDL or "bad" cholesterol by as much as 8%. Isoflavones are believed to prevent LDL levels from harming the walls of the blood vessels. While man-made estrogens can raise levels of blood fats called triglycerides, soy doesn't have this negative effect. A study by researchers at the University of Illinois at Champaign-Urbana, found that postmenopausal women with high concentrations of soy in their diet had stronger bones. A recent issue of the Mayo Health Clinic Health Letter noted that studies on soy have shown promising results in the prevention of heart disease, stroke, cancer, and hot flashes during menopause, as well as benefits for osteoporosis. One study involving more than 12,000 men indicated that drinking soy milk at least once a day was associated with a 70% reduction in the risk of prostate cancer. Research on soy and the prevention of colon cancer has also produced encouraging results. Remember we are NOT Doctors and have NO medical training.
