ST. LOUIS — Nearly a decade after the Food and Drug Administration permitted health claims for soy and heart disease prevention, The Solae Co. has unveiled research affirming soy protein helps reduce blood cholesterol levels.

The health claim allows the promotion of the daily intake of 25 grams of soy for lowering cholesterol levels and reducing the risk of heart disease.

Solae’s researchers conducted a meta-analysis to look at the totality of the evidence, published before and after the health claim was allowed. Of 150 studies on the subject, Solae’s team ranked 46 as "higher or moderate quality" and included them in the meta-analysis.

Their analysis found a total cholesterol reduction of 9.54 mg/dL and a 7.12 mg/dL reduction for L.D.L. cholesterol.

The findings were presented Nov. 10 at the American Heart Association 2008 scientific sessions in New Orleans.

"These findings build on the body of evidence that continues to strongly justify maintaining the currently approved health claim for the role of soy protein in lowering heart disease risk," said Priscilla Samuel, lead researcher of the meta-analysis and director of nutrition sales at Solae. "According to the American Heart Association, at a population level for every 1% reduction in blood cholesterol, there is a 2% to 3% reduction in the rate of coronary heart disease, which is still the leading cause of death in the United States. Our research confirms that soy protein is one way to reduce cholesterol."
