Human intervention study: anthocyanins supplementation and the impacts on gut microbiota

Dietary polyphenols are natural compounds occurring in plants, including foods such as fruits, vegetables, cereals, tea, coffee and wine. Epidemiological studies and associated meta-analyses strongly suggest that long term consumption of diets rich in plant polyphenols offer protection against development several chronic diseases. In this study, the long term consumption of anthocyanin-rich fruit juice impacts the gut microbiota enriching specific bacteria and increase the expression of important antioxidative markers.
