Sell Soy with Science

April is national soy month. That, plus the FDA's October 1999 soy protein/heart health claim approval, should put some snap in your sales. The following summaries are gleaned from the 27 studies that met FDA evaluation criteria. Use them to enhance your soy protein sales pitch.

• Soy protein can improve blood lipid profiles, according to a study published in the American Journal of Clinical Nutrition [1998;68 (3):545-51]. Soy protein isolate lowered LDL cholesterol and raised HDL cholesterol in postmenopausal women.
• Soy protein proved better than animal protein in a study published in the American Journal of Clinical Nutrition [1978;31(8):1312-21]. When healthy young women ate 44 g soy protein/day instead of animal protein for five weeks, they lowered their total cholesterol by 10 mg/dL.
• Healthy men and women lowered their LDL cholesterol by 9 percent when they substituted soy milk for cow's milk. The study, published in Clinical Investigative Medicine [1997;20(3):162-70], also showed that the subjects with the highest initial LDL-cholesterol levels and LDL/HDL ratios reduced their LDL cholesterol by 11 percent.
• Men with high cholesterol lowered their total cholesterol by 7 percent when they ate 57 g of soy daily. The study, published in American Journal of Clinical Nutrition [1981;34(9):1769-78], indicated that the men ate soy-based meat analogs and drank soy-based beverages.
