A systematic review and meta-analysis of beta-glucan consumption on glycemic control in hypercholesterolemic individuals
International journal of food sciences and nutrition (2015) · Meta analysis · n=603
Summary estimates of weighted mean differences (WMD) and 95% confidence interval was 0.05 mmol/L (-0.11, 0.02) for fasting glucose concentration and 0.75 pmol/L (-1.82, 3.32) for fasting insulin concentrations.
Based on meta-analysis showing mean reductions of 5.39 mmHg systolic and 2.66 mmHg diastolic. Effects are modest and may not be clinically significant for all individuals. GI side effects increase notably above 6g.
Based on multiple meta-analyses showing 0.24-0.32 mmol/L LDL reduction. Effect specific to oat beta-glucan, not yeast forms. FDA-approved health claim at 3g dose. GI side effects more common with oat forms.
