A study by researchers at NOVA University in Lisbon found that regular use of leger beer improved men’s gastrointestinal health and thus reduced the risk of certain diseases. The investigation was published in a newspaper today ACS Journal of Agricultural and Food Chemistry.
Previous studies have shown that drinking alcohol in moderation is good for your health. These benefits are related to the polyphenols in the drink. Polyphenols are a class of micronutrients found naturally in plants and, along with other compounds found in food, serve as antioxidants in the body.
As a result of various cellular processes, tissues undergo a phenomenon known as oxidative stress, which is associated with diseases such as cancer and heart disease, and antioxidants counteract this phenomenon. So, theoretically, a drink that contains polyphenols would be good for health, and the researchers wanted to know if beer consumption had a similar effect.
Has this not been studied before?
A previous study of both men and women showed that drinking non-alcoholic beer for 30 days improved the diversity of intestinal bacteria in the body. Bacteria and other organisms in the human gut, commonly referred to as microbiomes, are a new science because they have been found to play a role in the development of various diseases such as Parkinson’s.
Studies have also shown that the higher the diversity of intestinal bacteria, the lower the risk of disease. On the contrary, the study also showed that those who drank beer containing alcohol did not show intestinal diversity. Because the research project allowed participants to drink alcoholic and non-alcoholic beers, researchers at NOVA University decided to conduct a parallel study and avoid cross-cutting to determine the true effects of drinking beer.
How was the study conducted? What did he find?
Researchers recruited 19 male participants divided into two groups. Each participant was given a camp beer without the original label, so they did not know whether they drank alcoholic or non-alcoholic beer. Drink beer every day for four weeks without changing the level of physical activity or diet.
Samples of feces were collected from participants before and during the study to determine changes in microbiome diversity. In addition, weekly blood samples were taken from participants.
By the end of the four-week period, both groups showed an increase in bacterial gut diversity, although markers for their weight, body mass index, and heart health remained unchanged. The researchers also tested samples of feces for alkaline phosphatase, a sign of gastrointestinal health, and found that it improved in both groups.
Based on their findings, researchers believe that drinking beer every day can be beneficial for gastrointestinal health. Researchers recommend choosing non-alcoholic beer to maximize the benefits of alcohol.
Modulation of the intestinal microbiota may be an intermediary mechanism for the health effects of beer. In this randomized, double-blind, two-handed parallel test, 22 healthy men were encouraged to drink 330 ml of non-alcoholic beer (0.0% k / h) or alcoholic beer (5.2% k / k) daily during a 4-week follow-up. – period of increase. Blood and feces samples were collected before and after the intervention. The intestinal microbiota was analyzed by sequencing the 16S rRNA gene. Drinking non-alcoholic or non-alcoholic beer daily for 4 weeks did not increase body weight and fat mass and did not significantly alter the cardiometabolic biomarkers in the serum. Non-alcoholic and non-alcoholic beer increased the diversity of intestinal microbiota, which was associated with positive health outcomes and increased activity of faecal alkaline phosphatase, which is a sign of intestinal obstruction. These results show that the effect of beer on the modulation of intestinal microbiota is independent of alcohol and can be due to beer polyphenols.
