From now on, beer fans can enjoy their cool blond beer (or any other variety of the popular drink made from hops and malt) twice as much – with the best knowledge and belief that they are doing something good for their body and their health!
Yes, it’s true: As researchers have now found, drinking a small bottle of beer every day can have a positive effect on the intestinal flora, also known as the microbiome in the intestine, in men, as the study from Portugal shows.
This encouraging finding was obtained as part of a small pilot study that was carried out in Portugal. For this purpose, 22 healthy men were recruited for “medically postponed beer drinking”. Half of the subjects were then to enjoy a 0.33 liter bottle of 5.2% alcohol lager beer daily after dinner for four weeks. The other half were instructed to drink a small bottle of non-alcoholic lager per day for the same period.
The researchers are currently unable to explain exactly how these positive effects arise in the microbiome. However, they assume that the polyphenols, i.e. the secondary plant substances found in beer, could be responsible for this. It is just as conceivable that the microorganisms that arise in the beer through fermentation enrich the diversity of bacteria in the intestine – or it is the mixture of polyphenols and microorganisms.
According to the results, alcohol, on the other hand, does not seem to play a role. The team therefore emphasizes that drinking non-alcoholic beer is the healthier decision, as regular alcohol consumption has other unhealthy effects. Whether the results of the study can also be applied to the intestinal flora of women or the consumption of other types of beer must first be clarified in further studies.
