Is moderate drinking healthy? Causes dullness of the brain

A newly published study shows that even people who drink moderately have some of their brain functions that decay faster as they age.

According to the U.S., the researchers found that older people who drink regularly have a more pronounced brain atrophy than non-drinkers. The ability to fluently express language is also weaker, and whether or not the language is fluent is a measure of memory and thinking ability. Item standard. The researchers also found that this effect even occurs among those who are “moderate” drinkers. The standard for moderate drinking is about four to seven cups per week.

Although this finding does not prove that alcohol is completely harmful, experts point out that their supplemental evidence shows that in the past, “moderate drinking was beneficial for health” was not correct.

Published in the June 6 issue of the British Medical Journal, the study found that hippocampus shrinks more often in people who drink regularly than those who occasionally drink or abstain from alcohol. Dr. Anya Topiwala, a clinical lecturer and chief researcher in psychiatry at Oxford University, explained that the size of the hippocampus is related to memory. The shrinking of the brain area is one of the symptoms of early onset of Alzheimer's disease.

However, she also pointed out that there are many reasons leading to the shrinking of the hippocampus. Therefore, the findings of this study do not accurately show whether the drinkers have a greater risk of dementia. The study found that compared with people who abstained from alcohol, people who drink moderately have a more than three-fold reduction in the hippocampal area of ​​their right hippocampus.

The moderate drinking defined in the study was an average of 14 to 21 units of alcohol per week, roughly equivalent to 4 to 6 pints of beer or 5 to 7 glasses of red wine per week. The study also showed that compared with those who abstain from alcoholics, moderate and heavy drinkers' linguistic fluency has to decline for more than 30 years.

Last year, the United Kingdom revised its guidelines for "safe" moderate drinking, and the government currently recommends that men and women drink no more than 14 units per week (equivalent to five glasses of red wine). The U.S. guidelines are broader, suggesting that women do not drink more than a standard dose of glass a day, while men can drink up to two glasses. A standard dose is equivalent to a glass of 12 ounces of beer or a glass of 5 ounces of red wine.

In this regard, Tepira personally believes that the public should not be too confident in the safe drinking doses listed in the US guidelines, but should carefully reduce the amount of alcohol consumed.

In response, Dr. Tim Stockwell, director of Canada's Victoria University's Addiction Research Center, who did not participate in the study, said that the public should be skeptical and cautious about the use of moderate drinking.

Dr. Stockerwell has also been conducting related research in an attempt to verify the accuracy of "moderate drinking and health," because many studies claim that moderate drinkers have a lower incidence of heart disease than alcoholics and non-drinkers.

To this end, he and his colleagues analyzed the previous studies and discovered major flaws. The definition of "non-drinkers" is unclear. In many studies, those so-called “non-drinkers” may be those who abstain from drinking for health reasons, and those who started drinking during old age may also be healthier before drinking.
