Beer can improve the microbiome in the gut – a medical practice

Greater diversity of intestinal bacteria through lager

Men who in the recent study daily one alcoholic or non-alcoholic lager drank could change their composition Darmflora to increase. Compared to the period before the study Darmicrobiome one greater diversity of intestinal bacteria on.

Die American Chemical Society pilot study reports demonstrating that Consumption of lager has a positive effect on the diversity of the intestinal microbiome. The results were recently presented in the Journal of Agricultural and Food Chemistry.

Diversity in the gut is important for health

The human gut consists of countless microorganisms populated. This microbiome, often referred to as the intestinal flora, has a direct impact on well-being and health host.

Previous studies already have one greater diversity of intestinal bacteria with lower risk of chronic diseases such as diabetes and cardiovascular disease.

Beer has a beneficial effect on the intestinal flora

contains beer polyphenols like Microorganisms from fermentationwhich can positively affect the diversity of the intestinal flora, as shown by current research.

Drink beer for science

For a small study, 19 healthy men were randomly divided into two groups. All participants drank for four weeks after dinner 0.33 liters of non-alcoholic or alcoholic lager.

A bottle of beer daily promoted diversity in the gut

The intestinal microbiome of the subjects was examined before and after the study. The non – alcoholic beer group and the alcoholic beer group had and greater bacterial diversity in their intestinal microbiome than before the study.

Weight, body mass index and serum markers for heart health and metabolism were not adversely affected by moderate beer consumption, the researchers say.

The results of the study suggest that Consumption of a bottle of beer daily regardless of the alcohol content beneficial for intestinal microbiome works of men.

Non-alcoholic beer is a healthier choice

However, the Working Party emphasizes that non-alcoholic beer is a healthier choice because regular alcohol consumption can have other negative effects on the body that have not been studied in the study.

limitation of results

In addition, the number of participants was small and only men participated in the study. To confirm the positive effect of beer on the intestinal flora and to determine whether beer affects the microbiome in women in the same way, it would be necessary to verify the results in a larger group.
