Blood tests to determine the amount of cholesterol and triglycerides in the bloodstream are nearly always conducted after a 12-hour fast. Increasingly, however, researchers are interested in levels of cholesterol and other lipids, particularly triglycerides, in the bloodstream after eating, which has been shown to be associated with the development of atherosclerosis. Researchers at the University at Buffalo have shown that one way to counter this destructive rise in blood lipids after eating is to include soy products in the diet.
