Abstract
was decreased in HFCD-induced hyperlipidemia hamsters. Metabolites were changed after HFCD treatment and 9 differential metabolites belonged to bile acids and 8 differential metabolites belonged to amino acids. Those genera and metabolites were significantly associated with serum lipids. HFCD also disrupted the intestinal barrier. Oryzanol supplementation reversed the changes of the gut microbiota and metabolites, and intestinal barrier injury was also partly relieved. This suggests that oryzanol supplementation modulating the gut microbiota contributes to its anti-hyperlipidemia function, especially anti-hypercholesterolemia.
