This study aimed to evaluate and compare the effects of dietary fibers (DFs) of commercially important tree nuts (almond, cashew, hazelnut, pistachio, and walnut) on gut microbiota in vitro. Microbial compositions and short-chain fatty acids were determined using 16S rRNA sequencing and gas chromatography (GC), respectively. Neutral and acidic monosaccharides were analyzed using GC/MS and spectrophotometry, respectively. Our results revealed that cashew fibers exhibit higher butyrate formation compared to others. Accordingly, cashew fiber promoted butyric acid-producing bacteria-related operational taxonomic units (OTUs; Butyricimonas and Collinsella) at higher relative abundances. The higher butyrogenic capacity of cashew fiber is mainly attributed to its higher soluble/total DF ratio and remarkably distinct monosaccharide composition. Additionally, nut fibers stimulated family Lachnospiraceae- and Ruminococcaceae-related OTUs. These findings show that although the degree of promotion is nut type-dependent, nut fibers are generally capable of promoting beneficial microbes in the colon, further suggesting that DFs of tree nuts are contributing factors to their health-promoting effects. https://doi.org/10.1021/acs.jafc.3c01415
