Edible fungi polysaccharides (EFPs) and gut microbiota (GM) play an important role in lipid metabolism. The structure of GM is complex and can be dynamically affected by the diet. EFPs can be used as dietary intervention to improve lipid metabolism directly, or by regulate the GM to participate in the host lipid metabolism by a complex mechanism. In this paper, we reviewed that EFPs regulate the balance of GM by increasing the number of beneficial bacteria and decreasing the number of harmful bacteria in the intestinal tract. The metabolites of GM are mainly bile acids (BAs), short-chain fatty acids (SCFAs), and lipopolysaccharides (LPS). EFPs can promote the synthesis of BAs and increase the content of SCFAs that produced by GM fermented EFPs, but reduce the content of LPS to regulate lipid metabolism. This review provides a valuable reference for further elucidation of the relationship between EFPs-GM-lipid metabolism and EFPs targeted regulation of GM to improve public health.
