Doubts cast on soy-based food Heart group: Doesn't greatly cut cholesterol
By Jamie Stengle Associated Press Published January 23, 2006
DALLAS -- Veggie burgers and tofu might not be so great at warding off heart disease after all.
An American Heart Association committee reviewed a decade of studies on soy's benefits and came up with results that now cast doubt on the health claim that soy-based foods and supplements significantly lower cholesterol.
The findings could lead the Food and Drug Administration to re-evaluate rules that currently allow companies to tout a cholesterol-lowering benefit on the labels of soy-based food.
Based on its findings, the committee said it would not recommend using isoflavone supplements in food or pills. It concluded that soy-containing foods and supplements did not significantly lower cholesterol, and it said so recently published in the journal Circulation.
Nutrition experts say soy-based foods still are good because they often are eaten in place of less healthy fare such as burgers and hot dogs. But they don't have as much benefit as had been hoped on cholesterol.
The FDA in 1999 started allowing manufacturers to claim that soy products might cut the risk of heart disease after studies showed at least 25 grams of soy protein a day lowered cholesterol. A year later, the Heart Association recommended soy be included in a diet low in saturated fat and cholesterol.
But as more research emerged, committee members revisited the issue and reviewed 22 studies, finding that large amounts of dietary soy protein reduced LDL, or "bad" cholesterol, only about 3 percent and had no effect on HDL, or "good" cholesterol, or on blood pressure.
They did a separate analysis of isoflavones. The review of 19 studies suggested that soy isoflavones also had no effect on lowering LDL cholesterol or other lipid risk factors.
Still, the Heart Association notes that soy products such as tofu, soy butter, soy nuts and some soy burgers should be heart-healthy because they contain a lot of polyunsaturated fats, fiber, vitamins and minerals, and are low in saturated fat.
