摘 要：Resistant starch (RS) has attracted much researchers’ attention because of its health-beneficial effects. Gut microbiota obviously shapes human health， but the effects of RS supplementation on the changes of human gut microbiota remain unclear. This observational meta-analysis aimed to reveal the effects of RS intake on alpha diversity and composition of gut microbiota through meta-analysis. Two independent authors systematically searched articles from inception until February 2023 on four electronic databases. Twenty-four highly relevant trials were included conforming to Preferred Reporting Items for Systematic reviews and Meta-Analysis protocol， and a total of 816 individuals were included. Significant heterogeneity analyses revealed that RS intake notably decreased Shannon index (WMD: –0.11; 95% CI: –0.21， –0.01)， and stimulated the composition of health promoting bacteria genera， including Bifidobacterium (WMD: 1.75; 95% CI: 0.39， 3.11; WMD: 0.36; 95% CI: 0.04， 0.69)， Faecalibacterium (WMD: 0.70; 95% CI: 0.20， 1.20; ES: 0.91; 95% CI: 0.60， 1.23)， and Prevotella (WMD: 0.35; 95% CI: 0.01， 0.69). Taken together， the present study revealed that changes in the gut microbiota diversity and genera were correlated with RS supplementation， which may contribute to benefits in human health.
