How effective are dietary interventions in lowering lipids in adults with dyslipidemia?

Abstract

Diets lower in fat, higher in soy protein, or higher in fiber reduce serum total cholesterol, low-density lipoprotein (LDL), and triglycerides. More restrictive low-fat diets also lower high-density lipoprotein (HDL), while soy protein increases HDL. Average decreases in LDL range from 6.96 to 25.14 mg/dL, depending on the particular intervention and participants' baseline characteristics (strength of recommendation [SOR]: C, based on meta-analyses of randomized controlled trials [RCTs] measuring intermediate endpoints).
