Just one alcoholic drink per day can shrink the brain: Study

Just one alcoholic drink a day shrinks the overall volume of the brain, and the damage worsens as the number of daily drinks rises, a new study in the US has found.

US researchers found a link between drinking alcohol and reduced brain volume that begins at an average consumption level of less than one alcohol unit a day and rises with each additional drink.

The study was published Friday in the journal Nature.

One alcohol unit is 10 milligrams or 8 grams of pure alcohol. That means 25 milligrams or a single shot of liquor is one unit; a 16-ounce can of beer or cider is two units; and a standard 6-ounce glass of wine (175 milligrams) is two units.

The brains of nondrinkers who began consuming an average of one alcohol unit a day showed the equivalent of a half a year of aging, according to the study.

In comparison, drinking four alcohol units a day aged a person's brain by more than 10 years.

"It's not linear. It gets worse the more you drink," first author Remi Daviet, an assistant professor of marketing in the Wisconsin School of Business at the University of Wisconsin-Madison, said in a statement.

Doctors used to believe that moderate amounts of alcohol could provide a health benefit, especially to the heart and the brain, but recent research has proven otherwise.

A number of studies have found no amount of drinking to be healthy, and the World Heart Federation recently published a policy brief saying there is "no level of alcohol consumption that is safe for health."

Islam and other religions forbid alcoholic consumption and view it as sinful due to the physical, mental and spiritual harm it has on humans. In Islam, any food or drink that causes intoxication is strictly forbidden.

In the Quran, consuming alcohol is unlawful and referenced as incentives from the Satan.
