Soy isn't that great after all

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 are now casting 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 cholestorol-lowering benefit on the labels of soy-based food.
