The main food sources of polyphenols are fruits and vegetables, coffee, red wine and other plant-derived beverages, as well as chocolate.
Polyphenols in black tea have been proved to increase bifidobacteria and help stabilize intestinal permeability, which may explain the anti-inflammatory characteristics of black tea. Green tea has also been proved to increase Bifidobacterium and reduce the level of harmful bacterium Clostridium.
Coffee can support the proportion of healthy intestinal bacteria, has anti-inflammatory and antioxidant properties, reduces inflammation and enhances detoxification.
Drinking a glass of red wine every day is good for you and your microbial community.

Red wine is also a rich source of polyphenols that these intestines like. Just make sure you don't drink too much. Women drink one cup a day, while men drink two cups at most.
