A study by the King's College London has revealed that people who drank red wine have increased gut microbiota diversity (a sign of gut health) compared to non-red wine drinkers as well as a lower degree association Obesity and "bad" behavior had cholesterol.
In an article published today in the journal Gastroenterology a research team from the Department of Gemini and Genetic Epidemiology at King's College London investigated the effect of beer, cider, red wine, white wine and spirits on the Intestinal microbiota (GM) and its subsequent health in a group of 91
They found that the GM of red wine drinkers was more diverse than that of non-red wine drinkers. This was not observed when consuming white wine, beer or spirits.
The first author of the study, dr. Caroline Le Roy of King's College London said: "Although we have long been aware of the unexplained benefits of red heart health, this study shows that moderate red wine consumption is associated with greater variety and a healthier gut microbiota, in part explains the long-discussed positive health effects. "
The microbiome is the collection of microorganisms in an environment and plays an important role in human health. An imbalance between "good" and "bad" microbes in the gut can lead to adverse health effects, such as: As a decreased immune system, weight gain or high cholesterol.
The intestinal microbiome of a person with a higher number of different bacterial species is considered a marker of intestinal health.
The team found that the gut microbiota of red wine consumers contained a greater number of different bacterial species than non-consumers. This result was also observed in three different cohorts in the United Kingdom, the United States and the Netherlands. The authors considered factors such as age, weight, diet and socioeconomic status of participants and continued to view the association.
The authors believe that the main reason for the association lies in the many polyphenols in red wine. Polyphenols are defense chemicals found in many fruits and vegetables. They have many beneficial properties (including antioxidants) and act primarily as fuel for the microbes present in our system.
Senior author Professor Tim Spector of King's College London said: "This is one of the largest studies ever undertaken to investigate the effects of red wine in the entrails of nearly 3,000 people in three different countries and indicates that the high polyphenol levels in the grape skin could account for much of the controversial health benefits when used in moderation. "
noted that red wine consumption was associated with a reduction in obesity and" bad cholesterol, which is partly due to the intestinal microbiota.
"Although we observed a correlation between the consumption of red wine and the variety of gut microbiota, we rarely drank red wine. If you have to opt for an alcoholic beverage today, red wine is the one you have to pick, as it seems to potentially exercise one beneficial effect on you and your intestinal microbes, which in turn can have a positive effect on the weight and risk of heart disease, but it is still recommended to consume alcohol in moderation, " Le Roy added.
