A beer a day is good for the intestines!

It is consumed in all its forms, especially in summer: the Beer can be white, brown, blond, amber and even without alcohol. But one in the published study Journal of Agricultural and Food Chemistry specifically focused on lagers and showed that drinking one beer a day is good for your health! Especially for intestinal health: the variety of microbiota Gut would improve thanks to beer.

A whole ecosystem in our digestive tract

It is home to thousands of microorganisms: bacteriaof yeastsof Mushroomssometimes too virus that infect him. the gut microbes plays an essential role in health, through its influence on the digestion in particular, but also on the immune system and neurological. The greater its variety, the better Goal : For this reason, taking antibiotics worsens them, they kill a large part of the bacteria that inhabit and protect them intestinal flora. Food in general plays an important role in health, particularly through its contribution to the microbiota that feeds on fiber.

Beer, on the other hand, is made from it Grain sprouted and boiled: these are called malts. Depending on the original grain used and the cooking method, the result is a different beer. For example, dark and amber beers come from roasted grains. The malt is then blended through various processes hop and above all water. One of the most important manufacturing steps is the fermentation : Yeasts are added to the malt, hops and water mixture to enable the transformation sugar in gas and in alcohol. In 2019, University of Amsterdam researcher Eric Claassen claimed that certain strong beers improve gut microbiota probiotics they contain, although their effect on the intestinal flora is still controversial.

One lager a day, alcoholic or not, diversifies the gut microbiota

This time, researchers from the University of Lisbon decided to investigate the effects of lager on men’s health: 22 healthy men consumed 33 cl of lager every night for four weeks. for some of the alcohol-free beer, for other beers with about 5% alcohol. As the study explains, “Blood tests and materials Fecal samples were collected before and after the intervention period”, allowing the scientists to see the difference in the microbiota before and after the four weeks. This was also analyzed by sequencing genetics onrRNA 16S “, which represents a kind of ID card for bacteria and thus enables them to be distinguished.

So the researchers measured better Diversity of the microbiota after four weeks, hence a possible health-promoting effect. They also found that drinking one beer a day, alcoholic or not, did not cause elevation body weight and Dimensions body fat and did not significantly alter serum cardiometabolic biomarkers », Details of the study.

She concludes with the positive effects of beer on health, which she attributes polyphenolsof nutrient made from malt and hops and contains antioxidants. The study was only conducted on a small sample of men, so the team plans to conduct a similar study on a larger sample that would also include women. Attention, the study emphasizes that alcohol does not play off its health-promoting effects: beers without alcohol are then preferable, beers with alcohol in moderation!
