A government-commissioned study released Tuesday in the Journal of Studies on Alcohol and Drugs concludes that no level of alcohol consumption offers a protective health benefit, with risks of premature death and over 200 diseases rising even with one drink per day. The findings, originally commissioned under the Biden administration, were released independently after internal disputes surfaced regarding their inclusion in official U.S. dietary guidelines.
Why is there a conflict over alcohol research?
The dispute stems from a clash between scientific findings and policy implementation. Robert Vincent, a former official at the Substance Abuse and Mental Health Services Administration (SAMHSA) who led the project, alleged in an editorial that the Trump administration sought to “sideline” the research. According to Vincent, he was instructed to “kill the study” during his tenure. The U.S. Department of Health and Human Services (HHS) denied that the study was ignored, stating that the government reviewed the research alongside the broader scientific record to develop the 2025–2030 Dietary Guidelines for Americans.
The alcohol industry and various congressional committees actively lobbied against the study’s findings. A House oversight committee report previously labeled the research as “fraught with bias,” while the Distilled Spirits Council of the United States described the study as “irretrievably flawed.”
What does the latest science say about drinking?
The research indicates that the health risks associated with alcohol are more pervasive than previously understood. While older studies once suggested moderate drinking could improve heart health, modern research suggests those benefits disappear when controlling for factors like socioeconomic status and healthcare access. Dr. Timothy Naimi, director of the Canadian Institute for Substance Use Research and a study co-author, noted that while current dietary guidelines suggest consuming “less alcohol,” they lack the specific quantity-based advice necessary for public safety. The authors argue that one drink or fewer per day should be the recommended limit for adults.
Comparison of Findings
| Study Focus | Conclusion |
|---|---|
| New Independent Study | No protective effect; risks increase with any consumption. |
| Prior Govt-Commissioned Review | Moderate use associated with lower mortality but higher disease risk. |
How does alcohol affect long-term health?
According to the study, alcohol is linked to an increased risk of over 200 diseases, including various cancers and heart conditions. Researchers specifically excluded “all-cause mortality” metrics—which can be skewed by other lifestyle factors—to focus on deaths directly attributed to alcohol. Dr. Priscilla Martinez-Matyszczyk, a deputy scientific director at the Public Health Institute, noted that there is currently no verified evidence to suggest that the social benefits of drinking outweigh the biological health risks.
Health experts define “one drink” as a 12-ounce can of beer, a 5-ounce glass of wine, or a single 1.5-ounce shot of distilled spirits. Tracking these specific volumes is essential for understanding your personal health risk.
Frequently Asked Questions
- Is moderate drinking still considered heart-healthy?
No. Recent studies, including a 2019 analysis in The Lancet, indicate that moderate drinking offers no protective health benefits and may actually raise the risk of hypertension and stroke. - Why did the government release two different sets of information?
The government utilized multiple reviews to inform the 2025–2030 Dietary Guidelines. While the official guidelines encourage reduced consumption, the independent study provides a more granular, evidence-based argument for limiting intake to one drink or less daily. - Was the study’s data considered biased?
The study authors maintain that they were thoroughly vetted for conflicts of interest. However, industry groups and some congressional members have challenged the methodology, citing concerns over the researchers’ previous affiliations.
