Beer can improve the microbiome in the gut – healing practice

Greater diversity of intestinal bacteria through lager

Men who, as part of a recent study, on a daily basis alcoholic or non-alcoholic lager drunk could change the composition of them Darmflora to improve. Compared to before the study, Darmmikrobiom one greater diversity of intestinal bacteria On.

To die American Chemical Society reports on a pilot study showing that the Consumption of lager beer positively influences diversity in the gut microbiome. The findings were recently presented in the Journal of Agricultural and Food Chemistry.

Diversity in the gut is important for health

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

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

Beer has a beneficial effect on the intestinal flora

contains beer polyphenols how Fermentation microorganismswhich can positively affect gut flora diversity, as current research shows.

Drink beer for science

For the small study, 19 healthy men were randomly divided into two groups. All the 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 one bottle of beer per day regardless of the alcohol content beneficial for the intestinal microbiome works of men.

Non-alcoholic beer is the healthiest choice

However, the working group points out that non-alcoholic beer is the healthiest choice, as regular alcohol consumption can have other negative effects on the body that were not examined in the study.

limitation of results

Furthermore, 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 equally, the results should be verified in a larger group. (vb)
