A recent study suggests limiting alcohol consumption to one drink a day, contrasting with previous guidelines that allowed up to two drinks for men. The publication highlights the need for more concrete guidance for Americans.

The scientists who carried out the study, published in the Journal of Studies on Alcohol and Drugs, examined 56 systematic reviews on alcohol and health. The findings reveal a significant increase in the risk of mortality related to excessive alcohol consumption.

Data indicate that consumption of more than 6.5 drinks per week for men and more than 7 for women increases the risk of illness and injury. After 14 drinks a week, the risk of mortality rises to 1 in 25.

“One in 25 people is at very high risk,” said Jürgen Rehm, senior scientist at the Center for Addiction and Mental Health at the University of Toronto and co-author of the article, reported NBC News.

Priscilla Martinez-Matyszczyk, another of the authors of the new study and deputy scientific director of the Alcohol Research Group of the Institute of Public Health, clarifies that the study did not analyze mortality from all causes, but rather examined mortality specifically attributed to alcohol to avoid confounding factors, reports the Associated Press (AP).

Disagreement with previous policies

The study has highlighted differences with previous guidelines, including those from the Trump administration, which offered less precise recommendations. Even though the Biden administration released a report by scientists in 2025, its findings were not implemented.

The opinion of several experts highlights that the perception that alcohol is beneficial for health is a myth. The American Cancer Society suggests that it is ideal to avoid alcohol completely, especially for those who are at high risk for cancer.

Although the findings are about population patterns, the importance of each individual evaluating their personal risk is emphasized. The decision about alcohol consumption must be made with awareness of family history and the associated risks.

Risks associated with alcohol consumption

Alcohol consumption presents specific risks that vary substantially by age group, as the body and brain respond differently at each stage of life.

Children and adolescents (under 18 years of age)

This group is the most vulnerable due to incomplete brain development:

Young adults (18 to 25 years old)

Middle-aged adults (26 to 54 years)

Older adults ( 55 years)
