Resistant dextrin promotes beneficial fecal bacteria in high and low fiber diet populations: a randomized, double-blinded, controlled pilot study (opens in new tab)

Background and objectivesThe average intake of dietary fibers known to beneficially modulate the gut microbiota is below recommendations in high-income countries. This study aimed to evaluate the gut effects of resistant dextrin in healthy male adults with normal weight, consuming high (≥ 25 g/day; HF) or low (≤15 g/day; LF) levels of fiber as part of their usual diet.MethodsIn this randomized, double-blind, placebo-controlled trial, participants received either 15 g/day of resistant dextrin ...
