Research progress on the interaction between dietary polyphenols and intestinal microbiota
Dietary polyphenols are widely found in fruits,tea,and other foods,and have various active functions such as antioxidant and anti-inflammatory.In this paper,the research progress of the interaction between dietary polyphenols and intestinal microbiota was analyzed from 3 aspects:the effect of dietary polyphenols on the host,the relationship between intestinal microbiota and host health,and the interaction mechanism between dietary polyphenols and intestinal microbiota.In terms of host effects,dietary polyphenols have positive effects on host cardiovascular diseases due to their antibacterial and anti-inflammatory properties.Intestinal microbiota regulate immunity and other functions by producing metabolites such as propionic acid and aromatic amino acids,thereby enhancing the immune function of the host.In terms of the interaction between the two,the intake of dietary polyphenols can affect the types and quantities of intestinal microorganisms,regulate the balance of microbial communities,increase the proportion of probiotics,and reduce the number of harmful bacteria.The gut microbiota modifies the intake of dietary polyphenols,regulates their metabolism and absorption,and thus plays a role in the host.This study provides a reference for further exploring the role of dietary polyphenols in preventing and improving intestinal health.
