Impact of Diet on Plasma Lipids in Individuals with Heterozygous Familial Hypercholesterolemia: A Systematic Review of Randomized Controlled Nutritional Studies
Nutrients (2021) · Systematic review · n=837
A significant reduction in LDL-C levels was reported in 10 RCTs, including eight dietary supplement interventions (phytosterols, n = 6, omega-3, n = 1; guar gum, n = 1), one food-based intervention and one dietary counseling intervention.
Based on multiple meta-analyses showing dose-related trends for TSS improvement. 600mg/day most studied dose with significant benefit vs placebo in 73% of studies. Limited data on doses above 600mg.
Effects highly inconsistent across studies with 80% showing mixed results. Cuban studies show better outcomes than non-Cuban studies. One large RCT (n=143) found no significant LDL reduction versus placebo. Only modest effects supported when present.
