Is Plant Sterols a Good Strategy to Lower Cholesterol?

Cardiovascular disease (CVD) has emerged as the leading cause of dealth worldwide today. Lowering circulating total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) is one of the most effective approaches of CVD prevention. Dietary guidelines and health organizations approved using plant sterols (PS) as the alternative to conventional method in attenuating circulating TC and LDL-C levels and risk of CVD. However, current findings apprear to be controversial on the efficacy of PS. Giving the rise of the field "Nutrigenetics", single nucleotide polymorphisms (SNPs) such as CYP7A1-rs3808607 have been identified that strongly associate with cholesterol metabolism in response to PS intake, towards causing inter-individual variations. This review article aims to discuss the efficacy of dietary PS in managing cholesterol levels based on findings from recent studies. The scope includes reviewing evidence on supporting the efficacy, the metabolic claims, inter-individual variations as well as sitosterolemia associated with PS intake.
