It turns out that even half the alcohol of canned beer a day causes the brain to atrophy, and the more you drink, the more exponentially it gets worse.



From the results of analyzing the drinking habits of 36,000 people and the results of brain scans by MRI, it was found that the volume of the brain decreases even with alcohol of 10 ml per day, which is about half that of canned beer when converted to alcoholic beverages. I did.

More alcohol, less brain: Penn-led study find | Eurek Alert!

Past studies have shown that even moderate amounts of alcohol can cause brain atrophy.

'Drinking can cause brain atrophy even in moderate amounts,' found from data from 25,000 people-GIGAZINE



However, there are contradictory findings on the effects of consuming small amounts of alcohol, and some even suggest that consuming small amounts of alcohol is more beneficial to the brain in the elderly.

Therefore, a research team led by Professor Gideon Nave of the University of Pennsylvania analyzed the results of MRI scans of the adult brain enrolled in the UK Biobank , and from the data, the volume of white matter and calcareous in various areas of the brain. I did a study to calculate.

Using data from 36,678 people, Professor Neve said, 'Using a large data set is like getting a microscope or telescope with a more powerful lens. So many samples. If you have a lot of data, you can find subtle differences between drinking half a bottle of beer and emptying one bottle a day. '

As a result of comparing the amount of alcohol consumed and the volume of the brain and excluding factors such as aging of the brain due to aging, height, gender, smoking habits, socioeconomic status, and inheritance, even mild to moderate alcohol intake is the result of the whole brain. It was found to be related to volume reduction. Specifically, it was found that in the case of 50 years old, if the amount of alcohol consumed is 0 to 1 alcohol unit (10 ml) per day, the effect equivalent to half a year's aging can be seen. Furthermore, it was found that the effect of alcohol on the brain increases from 1 unit to 2 units for 2 years, 2 to 3 units for 3 and a half years, and 3 to 4 units for 4.9 years. rice field.

Beer in a 500ml can with 5% alcohol contains 25ml of alcohol, so drinking one can of beer a day will make a difference of more than two years at the age of 50. Will be ingested.



It is also known that the harm of alcohol increases at an accelerating rate, not proportional to the amount of drinking, such as when the data of alcohol intake used for analysis is set to 0 to 4 units, the effect increases sharply for 10 years. .. 'There is a lot of evidence that drinking and its effects on the brain are exponential,' added Remi Daviette of the University of Wisconsin-Madison, co-author of the paper. Alcohol has the greatest negative effect of any previous drink. In other words, putting up with the last drink is even more effective. '

Since this study only shows the correlation between drinking and brain volume, Professor Neve said, 'If you use a dataset that tracks young people over the long term, alcohol consumption and brain aging can be used. We may be able to identify the causal relationship between them, 'he said, motivating further research in the future.
