Phytosterols and citrus flavones: Powerful tools for healthy lipid profile management
By Kelly C. Heim, Ph.D.
As essential constituents of plant cell membranes, phytosterols are widely distributed in the plant kingdom and are particularly abundant in nuts, seeds, grains and vegetable oils. Meta-analyses of over 40 human clinical trials have established the efficacy of supplemental phytosterols in maintaining a healthy lipid profile. The rigor and depth of over 30 years of clinical research led to an FDA-approved health claim that “Scientific evidence establishes that phytosterols in the diet help to lower blood total and LDL cholesterol levels” and “Supplements containing at least 0.5 g per serving of phytosterols eaten with meals or snacks for a daily total intake of 2 g as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease.”
