What are polyphenols, and how do they impact the microbiome and gut health?

Polyphenols are plant-based compounds found in foods like berries, tea, dark chocolate, herbs, and spices. They act as antioxidants, and many of them also have anti-inflammatory properties.
​
A diet rich in polyphenols can help reduce markers of gut inflammation — such as faecal calprotectin — and support beneficial gut activity by increasing plasma IPA levels, which are linked to gut and overall health.
​
In short, polyphenols are a natural, everyday way to support your microbiome and gut health through the food you eat.
