The Effects of Resistant Starch on Biomarkers of Inflammation and Oxidative Stress: A Systematic Review and Meta-Analysis
Nutrition and cancer (2022) · Meta analysis · n=739
We used from the effect size, as estimated by the standardized mean difference (SMD) with 95% confidence intervals (95%CI) to perform the random method meta-analysis, with P value ≦0.05 as statistically significant.
Meta-analysis showed 17.24 mg/dL reduction in fasting glucose with stronger effects above 200 mcg/day. Effects primarily demonstrated in type 2 diabetes patients. Chromium picolinate shows higher bioavailability than other forms.
Meta-analysis showed modest 3.32 mg/dL reduction in fasting glucose. Effects were heavily influenced by small number of positive studies, with majority showing mixed results. Higher doses increase GI side effects.
