Good for the Gut

It is widely acknowledged that microbiome in our guts has a major influence in our metabolism, body weight, propensity to illness, immune system, and mood.


Also, there is broad agreement that dietary anthocyanins and their metabolites have potential health benefits via modulation of the gut microbiota. Increasing evidence supports the idea that anthocyanins can function as prebiotics, which contributes to the growth of certain commensal bacteria.


Anthocyanins and gut microbiota exhibit a two-way interaction to impact host physiology. Unabsorbed anthocyanins are exposed to microbiota-mediated biotransformation which produces glucose, an essential energy source required for bacterial growth. Gallic acid as another anthocyanin-derived metabolite was shown to reduce the growth of potentially harmful bacteria such as Clostridium histolyticum and Bacteroides spp. without any negative effect on measured beneficial bacteria (1)
