Caroline I. Le Roy et al found that moderate red wine consumption was associated with a healthier gut microbiota among red wine drinkers. Researchers also explored the effect of beer, cider, white wine and spirits on the gut microbiome (GM) and subsequent health benefits. They found that the GM of red wine drinkers was more diverse compared to non-red wine drinkers. This was not observed with white wine, beer or spirits consumption. The study also found that red wine consumption was associated with lower levels of obesity and ‘bad’ cholesterol, which was in part due to the gut microbiota. This result was also observed in three different cohorts in the UK, the US, and the Netherlands. The team took into account factors such as age, weight, the regular diet and socioeconomic status of the participants. The authors believe the main reason for the association is due to the many polyphenols in red wine that act as a fuel for the microbes present in our system.
