Their conclusion differs from the current U.S. dietary guidelines.

Americans should limit their alcohol consumption to no more than one drink per day, according to a study published Tuesday in the Journal of Studies on Alcohol and Drugs.

The recommendation — from an international team of scientists — differs from the U.S. dietary guidelines, both past and present. Previous guidelines recommended a daily limit of two alcoholic drinks for men and one for women. The latest version, released by the Trump administration in January, is less precise. It recommends only that Americans “consume less alcohol for better overall health.”

The current less-is-best message is accurate but too vague, said study co-author Priscilla Martinez-Matyszczyk, deputy scientific director of the Alcohol Research Group at the Public Health Institute, an independent nonprofit organization in California. People need quantified guidance so they can make informed decisions about their drinking, she said.
