Application of phytosterols in management of plasma cholesterol

Phytosterols are a class of natural active ingredients widely found in foods of plant origin. Phytosterols and their derivatives have recently received considerable attention because of their potential beneficial effects on human health, such as cholesterol-lowering, anti-inflammation, anticancer, antioxidation, and cardiovascular-protective activities. This chapter is mainly to update the recent research regarding the cholesterol-reducing benefits of phytosterols and the associated underlying molecular mechanisms involved. In addition, the structural diversity and sources of dietary phytosterols and the current commercial applications of phytosterols will be reviewed.
