in the last 12 years soy has been believed to lower ldl-c [bad cholesterol]. however recent data has not shown soy to be a practical means to lower ldl-c. in order to achieve any meaningful ldl-c reduction large amounts of soy are required. even when individuals consume half their daily protein with soy protein only a very small reduction (3%) in ldl-c is achieved. soy seems to be a more efficacious lipid-lowering agent in persons with marked hyperlipidemia. it should be noted that reduction in lipids may be due to replacing high-fat animal protein with soy rich foods that may indirectly result in lipid reduction via a reduction in saturated fat intake.
can soy help lower cholesterol?
