MADRID, August 9 ― The intestine is sometimes called the second brain, because we now know that the two organs are so connected that their relationship can influence our emotions. However, it also seems that the intestinal microbiota could have a role to play in our alcohol consumption.

One small drink, then another, and maybe one more…you may be only too aware that your alcohol intake is high. And while we’re learning to drink in moderation and say no to another drink, in reality it might be more complicated for some people – especially if the composition of their gut microbiota echoes the findings of researchers at the Complutense University of Madrid (UCM) in Spain. . Indeed, scientists have discovered that a certain profile of the intestinal microbiota can influence our behavior towards alcohol.

As part of their surveys, they interviewed 507 young volunteers who not only answered questions about their drinking habits, but also provided samples of feces. These samples were used to place them on the Bristol Stool Scale, a visual diagnostic tool that classifies human feces into seven families. Bacteriological samples were also taken. This organic evidence could then be compared to the same samples from volunteers who did not drink alcohol.

When male rats were transplanted with faecal samples from alcohol-dependent animals, their voluntary consumption of alcoholic substances was found to be increased. On the other hand, when the rats received a dose of antibiotics, which work by preventing the growth of bacteria, the scientists were able to reverse the trend and reduce alcohol consumption.

The bacteria responsible for forming the gut microbiota of heavy drinkers have yet to be precisely identified. However, Spanish scientists believe that these recent discoveries already make it possible to consider probiotics, prebiotics and also synbiotics as effective treatments for alcohol-induced intestinal disorders.

In 2018, American researchers had already found a link between alcohol and the microbiota of the mouth. Women who drank more than two drinks a day and men who drank more than three drinks a day were distinguished from non-drinkers by the proliferation of “bad” bacteria in the mouth, some of which could affect the health of the gums, among other things. . . ― Studio ETX
