The dual interaction of polyphenols with gut microbiota: An opportunity for nutritionists and food technologists

Discusses the dual interaction between colon microbiome and polyphenols.  The polyphenols modulate the microbiota population, and the microbiota can metabolize polyphenols to produce metabolites with better bioavailability than the original compounds, and often extend and improve their biological effects.  Dietary polyphenols favor the development of some bacterial groups, while inhibiting the growth of other bacterial groups, and this can be beneficial for gut health. These insights provide opportunities to develop new functional foods, nutritional treatments, and in the development of specific food products that will target specific enterotype.
