Beer can improve the microbiome in the gut – healing practice

Greater diversity of gut bacteria through lager

Men who, as part of a recent study, daily one alcoholic or non-alcoholic lager drank could change the composition of their Darmflora to enhance. Compared to before the study, Darmmikrobiom one greater diversity of gut bacteria on.

Die American Chemical Society reports on a pilot study demonstrating that the Consumption of lager beer positively influences the diversity in the gut microbiome. The results were recently published in the “Journal of Agricultural and Food Chemistry” presented.

Diversity in the gut is important for health

The human intestine is made up of innumerable microorganisms populated. This microbiome, often referred to as the gut flora, has direct influence on well-being and health of the host.

Previous studies already have one greater diversity in gut bacteria with a lower risk of chronic diseases how Diabetes and cardiovascular diseases tied together.

Beer has a beneficial effect on the intestinal flora

contains beer polyphenols such as Microorganisms from fermentationwhich can positively influence the diversity of the intestinal flora, as current research shows.

Drink beer for science

For the 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 a day promoted diversity in the gut

Before and after the study, the subjects’ gut microbiome was examined. Both the non-alcoholic beer group and the alcoholic beer group had a greater bacterial diversity in their gut microbiome than before the study.

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

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

Non-alcoholic beer is the healthier choice

However, the working group emphasizes that alcohol-free beer is the healthier choice, as regular alcohol consumption can have other negative effects on the body that were not examined in the study.

limitation of the results

In addition, the number of participants was small and only men took part in the study. To confirm the positive effect of beer on gut flora and to see if beer affects the microbiome in women in the same way, the results would need to be verified in a larger group. (vb)
