Study TitleGlobal, distinctive and personal changes in molecular and microbial profiles induced by specific fibers in humans (Untargeted)
Study SummaryDietary fibers act through the microbiome and improve cardiovascular health, metabolic disorders and cancer prevention. To understand health benefits of dietary fiber supplementation we investigated two popular purified fibers, arabinoxylan (AX) and long-chain inulin (LCI), and a mixture of five fibers. We present multi-omic signatures of metabolomics, lipidomics, proteomics, metagenomics, a cytokine panel and clinical measurements on healthy and insulin resistant participants. Each fiber is associated with fiber-dependent biochemical and microbial responses. AX consumption associates with a significant reduction in LDL and an increase in bile acids, contributing to its observed cholesterol reduction. LCI is associated with an increase in Bifidobacterium. However, at the highest LCI dose there is increased inflammation and elevation in the liver enzyme alanine aminotransferase. This study yields insights into the effects of fiber supplementation, it provides insights into mechanisms behind fiber induced cholesterol reduction, and it shows effects of individual, purified fibers on the microbiome.
