Regulation of resistant starch, non-starch polysaccharides, resistant oligosaccharides and lignin on the gut microbiota and association with their health benefits

. Thirdly, the populations of short-chain fatty acid (SCFA)-producing bacteria can be regulated by DFs, suggesting a potential role of SCFAs in health benefits. Additionally, the degradation mechanisms of DFs through polysaccharide utilization locus systems of the gut microbiota and the potential negative effects of excessive DF intake are briefly discussed. By providing a comprehensive overview, this review is expected to deepen the understanding of the regulation of the gut microbiota by DFs, which may inspire further studies for better DF application in health areas.
