The Effects of Dietary Fiber on Metabolic Health and Gut Microbiota

Abstract

Glucolipid metabolic disorders (GLMD) are fast-going health concerns worldwide. There is a growing interest in researching nutritional approaches that can enhance human health and it is commonly known that dietary fiber has prebiotic effects. This paper investigates the relationship between dietary fiber and GLMD, with a focus on obesity and type 2 diabetes. Dietary fiber mechanisms in modulating glucolipid metabolism. Specifically, it examines DF’s role in regulating glycemic levels and lipid metabolism. Also, five separated experiments conducted on healthy adults are listed to show the relationships between dietary fiber and short-chain fatty acids (SCFAs) production. The findings underscore dietary fiber’s potential as a therapeutic intervention for mitigating GLMD by multiple pathways, including improving insulin sensitivity, promoting satiety, and modulating gut microbiota. Overall, the insights provided in this review contribute to a deeper understanding of dietary fiber’s therapeutic potential and pave the way for future research and applications in the field of metabolic disorders.
