Research Progress of Dietary Fiber and Intestinal Flora Regulating Fat Metabolism
Fiber is an important nutrient component in animal diets and an important influence factor on intesti-nal flora.Dietary fiber can not be directly digested and utilized by the animal body itself,but is metabolized by intestinal microorganisms to produce metabolites such as short chain fatty acid(SCFA).Dietary fiber can af-fect fat metabolism by regulating intestinal flora composition;intestinal flora can affect the metabolites of dieta-ry fiber,and participate in the regulation of metabolic processes such as fat oxidation and synthesis through me-tabolites such as SCFA.In this paper,the physicochemical properties of dietary fiber and the composition of in-testinal flora were reviewed,and the research progress and mechanism of the interaction between dietary fiber and intestinal flora in regulating fat metabolism were mainly discussed,in order to provide reference for the ap-plication of dietary fiber composition in regulating fat metabolism in animal production.[Chinese Journal of Animal Nutrition,2024,36(6):3507-3513]
