Abstract In recent years，the interaction of tea polyphenols and gut microorganisms has gradually be⁃
come a research hotspot in food science，nutrition and biology. The active substances from tea polyphenols
produced by intestinal microorganism metabolizing have the effects of anti-oxidation，reducing lipid and
treating inflammation，etc. The tea polyphenols could affect human health by regulating intestinal microor⁃
ganism. We mainly summarized the absorption of tea polyphenols in body，the metabolic fate of tea poly⁃
phenols by intestinal microorganism，the modulatory effects of catechins on gut microbiota composition，
and their effects on reducing blood lipids，reducing fat accumulation，maintaining intestinal barrier，which
could provide some references for the study of bidirectional effects of tea polyphenols and intestinal microor⁃
ganism in improving human health.
