Red wine facilitates bacterial diversification of the intestinal microbiome

A further study confirms the positive qualities of red wine. This time it’s a team of researchers at King’s College London who made the discovery.

In fact, researchers have found that those who regularly drink moderate amounts of red wine have a greater diversity regarding the intestinal microbiome, which in itself is a sign of better bowel health. They also found a link between red wine drinkers and lower levels of obesity and bad cholesterol.

The researchers analyzed the effects of beverages such as beer, cider, red or white wine and other alcohol on the intestinal microbiome. The dataset they analyzed was for 916 UK female twins. They discovered that those who drank red wine had a more diversified microbiome than those who drank white wine or other beverages.

The intestinal microbiome is one of the most important factors for human health and among those most analyzed at the research level. Even the slightest imbalances, for example between the amounts of “good” microbes compared to “bad” microbes, can lead to different pathologies, weight gain or high cholesterol.

The researchers found that regular consumers of red wine had a greater number of different bacterial species in their intestines than non-consumers of this drink. The researchers also considered various factors including age, weight, diet and socioeconomic status of the participants.

The reason, according to the researchers, is due to the polyphenols present in red wine, chemical substances, which among other things are also present in different types of vegetables and fruit, which show various beneficial properties, primarily antioxidants. These are substances that can act as “fuel” for bacteria within the body.

In any case, we speak of moderate quantities of wine, as Caroline Le Roy, first author of the study, well explains: “Although we observed an association between the consumption of red wine and the diversity of intestinal microbiota, drinking red wine rarely, for example once every two weeks, it seems to be sufficient to observe an effect. If today you have to choose an alcoholic beverage, red wine is the one to choose as it seems to potentially have a beneficial effect on you and your intestinal microbes, which in turn can also help [to manage] the weight and risk of diseases heart. However, it is advisable to consume alcohol in moderation.”
