Studies show that drinking beer a day is good for your gut

Portuguese researchers have discovered that this drink contributes to increasing the diversity of good bacteria in the region.

Drinking lager beer a day is good for your health.According to a study published in the journal Journal of Agricultural and Food Chemistry
Habits can increase the number of good bacteria in the intestines and reduce the risk of developing heart disease and type 2 diabetes.

It is not news that the composition of the gut microbiota affects our health. In a new study, researchers at Universidade NOVA de Lisboa in Portugal sought to understand whether moderate beer consumption could increase gut microbiota diversity. This has already been proposed, but has not been proven in previous studies.

To test this hypothesis, they conducted a double-blind, randomized trial of 19 healthy men aged 23-58 years. Participants were divided into two groups and drank 330 ml of alcoholic or non-alcoholic beer with dinner daily for a month. Volunteers were instructed not to change what they ate or drank or how they exercised. There was no control group.

The results showed that after that period, both groups had a 7% increase in gut bacterial type and levels of alkaline phosphatase in feces, a measure of gut health. In addition, there were no differences in volunteer weight, fat mass, or cholesterol levels.

According to researchers, reduced bacterial diversity in the gut is associated with diabetes and cardiovascular disease. Therefore, the increase has the opposite effect.

The beneficial effects of beer on the microbial flora (a collection of bacteria and fungi that live in our bodies) are thought to be related to the polyphenols and microorganisms that promote its fermentation. Polyphenols are highly antioxidant micronutrients naturally found in plants, such as the hops used in beer. Beer is the only source of hop polyphenols in the human diet. This ingredient is used in the industry to give drinks its aroma and bitterness.

Although this study only covers lagers, it is expected that all types of beer will have the same effect on the microbiota. Beer with a high amount of yeast, such as unfiltered, is believed to be even more effective.

Researchers recommend that people choose this option, as results have also been observed with non-alcoholic beer. According to them, some studies show that there is no safe level of alcohol consumption, as low intakes already increase the risk of some types of cancer and other illnesses.
