Abstract:

In recent years, the interactions between the gut microbiota and polyphenols have gradually become a hotspot
in food science, nutriology and biology. The functions of ployphenols such as antiaging, antitumor, and preventive effects
on cardiovascular and cerebrovascular diseases mainly rely on their metabolism by the gut microbiota. The metabolites of
ployphenols by intestinal microorganisms affect human health by influencing the gut microbial community. On the basis of
an extensive review of relevant literature, this paper summarizes recent progress in understanding the release and metabolism
of dietary bound phenolics by the gut microbiota under the influence of several factors, and the influence of polyphenols as
well as their metabolites on the gut microflora and related enzymes, aiming to provide valuable references for in-depth study
on the interactions between the gut microbiota and dietary polyphenols.

Key words: polyphenols, gut microbiota, metabolism, interaction
