A large new analysis finds that alcohol-related harms begin at lower levels of drinking than many people assume and argues U.S. guidance should recommend no more than one drink per day for both men and women.
Published June 8 in the Journal of Studies on Alcohol and Drugs, the report combined multiple national datasets — including federal health surveys, mortality records, alcohol consumption data and disease statistics — and reviewed 56 systematic reviews and meta-analyses. Rather than following a single cohort over time, the analysis pooled broad sources to estimate lifetime risks linked to different drinking levels.
Key findings
– The authors found no clear net health benefit from low-level alcohol consumption. Any small cardiovascular advantages suggested by earlier observational studies were outweighed by harms across cancers, injuries and other conditions.
– Lifetime alcohol-attributable mortality surpassed 1 death per 1,000 people at about 6.5 drinks per week for men and about 7 drinks per week for women.
– Risk rose rapidly beyond those levels. The lifetime risk of an alcohol-related death exceeded 1 in 100 people at roughly 8.5 drinks per week for both sexes.
– At 14 drinks per week — the level equivalent to the former U.S. recommendation of up to two drinks per day — the estimated lifetime risk of an alcohol-attributable death for men was about 1 in 25 (4%).
Cancer and other harms
The study highlighted elevated cancer risks associated with alcohol, including cancers of the throat, liver, colon and rectum, and breast. Several cancer risks increased even at relatively low levels of consumption.
The researchers also emphasized that drinking pattern matters. Binge or heavy drinking on single occasions increases the risks of breast cancer, cardiovascular events, injuries, suicide attempts, motor vehicle crashes and interpersonal violence. Two people who consume the same total alcohol each week can face very different risks depending on whether drinking is spread out or concentrated in heavy episodic sessions.
Interpretation and recommendations
Based on their modeling, the authors recommend that U.S. dietary guidance advise current drinkers to limit intake to no more than one drink per day for both males and females. They conclude that alcohol-related mortality and other harms begin at lower consumption levels than some prior guidance suggested, and therefore many people would reduce risk by drinking less.
Clinical experts quoted in the report urged a personalized approach to alcohol counseling. Rather than relying on a single universal threshold, clinicians should consider an individual’s health status, risk factors and goals. Some groups — including people who are pregnant or trying to conceive, those with certain medical conditions, elevated cancer risk, liver disease, or a family history of alcohol use disorder — may choose to avoid alcohol entirely.
Context and controversy
The study was originally commissioned to inform the 2025–2030 Dietary Guidelines for Americans. Some of its findings were released in 2025, but the final federal guidelines released subsequently did not include a specific daily limit for alcohol, instead advising that Americans “consume less alcohol for better overall health.”
Publication of the full analysis followed a period of political debate and criticism from industry groups and some members of Congress, who questioned the study’s development and potential bias. Federal officials have responded that dietary guidelines are informed by the totality of the scientific record rather than a single report.
What this means for people who drink
The study adds to a growing body of evidence that even socially accepted, moderate drinking carries measurable long-term risks. For people who choose to drink, consuming less and avoiding heavy episodic drinking are among the most effective ways to reduce those risks. Health professionals increasingly recommend individualized conversations about alcohol that take into account personal health, family history and life goals.
