Abstract

Supplementation with resistant starches of different structures led to divergent shifts in key bacterial taxa abundance and distinct butyrate or propionate outcomes. A recent randomized controlled trial (RCT) reported by Deehan et al. showed similar responses within treatment groups and dose-response plateauing at 35 g/d. These results support a proposed alignment of discrete dietary fiber (DF) structures with gut bacteria.

Keywords: dietary fiber; discrete structures; gut microbiome; human; resistant starch; short-chain fatty acids.
