Are you looking for a good reason to open a bottle of red wine tonight? Here she is all found. Researchers at King's College London have just published a study in the newspaper Gastroenterology, in which they claim that red wine would be good for the gut microbiota.
This discovery would explain the many benefits attributed to long-standing red wine. The microbiota, a set of microorganisms, plays a very important role in the immune system, weight gain and cholesterol levels. The more numerous and diverse the good bacteria, the better the health.
Benefits attributed to polyphenols
For their work, the researchers first began by studying the effects of beer, cider, spirits, red wine and white wine on the gut microbiota of 916 British twins, taking into account their age, their weight, diet and socio-economic status. Benefits have only been observed with red wine. Those who consumed them in the study had a greater variety of intestinal bacteria than those who had not. Similar results, the authors of the study say, have also been observed in three different cohorts in the United Kingdom, the United States and Belgium.
For researchers, these results could be explained by the richness of red wine polyphenols. Naturally present in fruits and vegetables, they have antioxidant properties, which protect against many diseases such as cancer and heart disease and serve as a fuel for bacteria present in our body. "This is one of the largest studies ever devoted to exploring the effects of red wine on the intestines of nearly three thousand people in three different countries," Tim Spector, the lead author of The study shows that high levels of polyphenols in grape skins could largely explain the still controversial effects of red wine.

Sporadic consumption is sufficient
In their publication, however, the authors draw attention to the fact that it is not necessary to "lift the elbow" daily to benefit from the benefits of drinking. "Although we have observed an association between the consumption of red wine and the diversity of gut microbiota, drinking red wine infrequently, for example once every two weeks, seems to be enough to observe an effect," says researcher Caroline Le Roy. Excessive consumption may actually upset your bowels and your health in general.
