Here's something interesting I learned today - the powerful impact of polyphenols on the gut microbiome.

Polyphenols are amazing plant compounds that are antioxidants, they are anti-inflammatory and they are really beneficial to the gut microbiome.

Polyphenols are found in some of my favourite foods: dark chocolate, berries, nuts, vegetables, black tea and red wine!

This easy-to-understand AtlasBioEd blog-post provides a great description of the two-way mutually beneficial relationship that exists between polyphenols and gut microbes.

"In return for being transformed into bioavailable metabolites (suitable for use by your body), dietary polyphenols promote the growth of beneficial bacteria and prevent that of opportunistic bacteria.

The mutual relationship shared between polyphenols and gut microbiota is thought to contribute to your health. Some studies have shown that polyphenols promote the growth of probiotic bacteria like Bifidobacterium and Lactobacillus."

Plus the blogpost contains a really long list of the rainbow of fruits and vegetables that contain polyphenols.

Polyphenols are another great reason to enjoy dark chocolate and a glass of red wine!
