Mutual interaction between gut microbiota and protein/amino acid metabolism for host mucosal immunity and health

In recent years,many studies have shown that the intestinal microflora has various effects that are linked to the critical physiological functions and pathological systems of the host.The intestinal microbial community is widely involved in the metabolism of food components such as protein,which is one of the essential nutrients in diets.Additionally,dietary protein/amino acids have been shown to have had a profound impact on profile and operation of gut microbiota.This review summarizes the current liter-ature on the mutual interaction between intestinal microbiota and protein/amino acid metabolism for host mucosal immunity and health.
