02 Sep 2019 --- Red wine drinkers have an increased gut microbiota diversity and lower levels of obesity and “bad” cholesterol, according to a study from King’s College London, UK. The researchers compared the effects of beer, cider, red wine, white wine and spirits on the gut microbiome and subsequent health in 916 UK female twins. This diversification effect, which was not observed with other drinks, is likely caused by red wine’s many polyphenols. However, the researchers caution that the alcohol must still be consumed responsibly.
