Red wine could be good for the gut, increasing the number of different types of helpful bacteria that can live there, according to researchers.
The benefits are likely to come from polyphenols – compounds that white wine, beer and cider have far less of, the King’s College London team says.
A glass a fortnight was enough to make a difference, but researchers say the findings are not an excuse to binge.
Polyphenols are also found in many fruits and vegetables.
Why does it matter?
Polyphenols, such as resveratrol in the skin of red grapes, are micronutrients that are thought to have beneficial properties and act as a fuel for useful microbes living inside our bowel.
