Phytosterol Supplementation and Lipoprotein Subfractions

The goal of this clinical trial was to evaluate the effects of phytosterol supplementation to the diet on lipids, LDL and HDL subfractions, and on the quality of LDL in apparently healthy subjects. The main questions it aims to answer are: * do phytosterols reduce LDL-cholesterol and modify LDL and HDL subfractions? * do phytosterols modify the quality of LDL? Participants were aleatory selected to diet alone (D) or diet plus phytosterols (DP, 2.6 g divided in two doses, with meals) for 12 weeks, followed by a 7-day washout period, where treatments were switched for another 12-weeks.
