Abstract

The regulation of dietary fiber (DF) on gut microbiota plays an important role in the occurrence and development of metabolic syndrome (MetS). However, there are few studies on the mechanism of soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) on gut microbiota. Through systematic review and integration of recent studies, this paper reveals that SDF regulates glucose and lipid metabolism mainly through rapid fermentation-metabolite signaling pathway. While IDF changes the structure of intestinal flora through physical structure-slow-release fermentation. The two complement each other and act together on the prevention and treatment of MetS. Therefore, this paper proposes that the recommendation of DF intake should be changed from simply increasing a certain type of DF to increasing the ratio of SDF and IDF, and then to individualized intake for different individuals. This can provide theoretical basis and practical guidance for the dietary prevention and treatment of MetS.
