The combination of effect sizes, regarding the random-effects model, demonstrated significant changes in ALT serum levels after intervention (WMD: -1.48 U/L; 95% CI: -2.33 to -0.64; P = 0.001), and AST (WMD: -1.10 U/L; 95% CI: -1.70 to -0.51; P < 0.001).
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 meta-analyses showing FPG reduction of 0.59-0.82 mmol/L and HbA1c reduction of 0.63%. Studies primarily used berberine HCl with low bioavailability. Effects require divided doses and may take 8-12 weeks.
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.
