Abstract

Intestinal microbiota plays an important role in human health, and their interactions and metabolism can affect the physiological conditions of the human body.Dietary fiber is the main source of energy for gut bacteria, promoting human health by regulating the composition of gut microbiota and promoting the production of short chain fatty acids (SCFA).Dietary fiber and gut bacterial solution from feces are mixed to conduct in vitro fermentation experiments at 37 ℃.This article reviews the effects of dietary fiber on gut microbiota and the fermentation properties changes of dietary fiber during in vitro fermentation experiments.The different physical and chemical structures of dietary fiber are key factors which can determine fermentation rate, short chain fatty acid profile, and growth of different bacterial communities.However, there are few reports on the impact of dietary fiber from different sources on healthy gut ecosystems.The regulatory effects of dietary fiber from different sources and properties on human gut microbiota would be studied, to promote health through dietary fiber.
