Systematic review of the mechanisms and evidence behind the hypocholesterolaemic effects of HPMC, pectin and chitosan in animal trials
Food chemistry (2016) · Systematic review
Systematic review of animal trials examining the cholesterol-lowering mechanisms of HPMC, pectin, and chitosan.
Meta-analysis (Brown 1999) found a roughly linear -0.045 mmol/L total-cholesterol drop per gram of soluble fiber within a 2-10 g/d range; the effect is small and plateaus, and GI tolerance limits higher intakes. Effect is weaker in people with normal baseline cholesterol.
