Özet
This study aimed to evaluate and compare the effectsof dietaryfibers (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 determinedusing 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 higherbutyrate formation compared to others. Accordingly, cashew fiber promotedbutyric acid-producing bacteria-related operational taxonomic units(OTUs; Butyricimonas and Collinsella) at higher relative abundances. The higher butyrogenic capacityof cashew fiber is mainly attributed to its higher soluble/total DFratio and remarkably distinct monosaccharide composition. Additionally,nut fibers stimulated family Lachnospiraceae- and Ruminococcaceae-related OTUs. These findings show that althoughthe degree of promotion is nut type-dependent, nut fibers are generallycapable of promoting beneficial microbes in the colon, further suggestingthat DFs of tree nuts are contributing factors to their health-promotingeffects.
