Describe the effects of plant sterols (like those in Benecol, Take Control, and Minute Maid Heart Wise orange juice) on cholesterol

The article reviewed several studies and found that the sterols reduce the production of cholesterol. There are several other studies that have shown a reduction of cholesterol with a low-fat, high-fiber diet that included plant sterols. The American Heart Association recommends them. However, the article below points out that some findings support the hypothesis that plant sterols might be an additional risk factor for coronary heart disease. This review article stated that: "From the review of these studies, it is apparent that sitosterol is a useful dietary supplement for the lowering of plasma cholesterol. Nevertheless, this plant sterol should be used with caution in certain individuals who have a higher absorption rate of sitosterol
