A study commissioned by President Joe Biden’s administration to investigate was released independently on Tuesday, after President Donald Trump’s administration decided not to feature the researchers’ findings in as it faced pushback from the alcohol industry and a congressional committee.
The findings of the study, in the Journal of Studies on Alcohol and Drugs, were in line with years of research, saying that health risks go up with just one drink a day and no level of alcohol has a protective effect on mortality. Even levels considered 鈥渕oderate鈥� of premature death and more than 200 diseases, including heart disease and cancer, researchers found.
The new study was one of two government reviews meant to help inform the new dietary guidelines. Released earlier this year, the guidelines advised consuming 鈥渓ess alcohol for better overall health.鈥� The authors of the independently released study say that didn鈥檛 provide detailed practical advice about the risks of drinking.
One of the officials involved in the study commissioned by accused of 鈥渟idelining鈥� the research 鈥� an allegation the Trump administration denies.
Robert Vincent, a former Substance Abuse and Mental Health Services Administration alcohol policy official who led the yearslong effort, made the accusations in an editorial published alongside the study. Vincent was laid off last year as part of .
鈥淭he challenges confronting alcohol policy today are not rooted in scientific uncertainty,鈥� Vincent wrote. 鈥淲hat remains contested is whether evidence will meaningfully inform policy when it conflicts with commercial interests.鈥�
The dispute over the study underscored the increasingly tense relations between the medical and scientific community and the Trump administration, which has questioned or ignored longstanding science in its policymaking, fired a slew of from the federal workforce and cut scientific grants that proponents say help keep the U.S. at the forefront of medical innovation.
Industry and congressional Republicans pushed back on the study
After the study’s researchers released a draft report last year, the alcohol industry mobilized against it, launching campaigns to discredit its work. The House oversight committee also criticized the study, releasing a report earlier this year that called it 鈥渇raught with bias鈥� and accused the study authors of having predetermined conclusions based on their past research and affiliations.
Emily Hilliard, a spokesperson for the U.S. Department of Health and Human Services, denied any notion that the findings weren’t considered.
HHS and the U.S. Department of Agriculture “reviewed the study alongside the broader body of available scientific evidence and followed the established process for developing the 2025鈥�2030 Dietary Guidelines for Americans,鈥� she said. 鈥淭he Guidelines are informed by the totality of the scientific record, not any single report or analysis.鈥�
Vincent told The Associated Press in an interview that the researchers were thoroughly vetted for conflicts and the findings were scientifically sound. He said that while he was in the Trump administration, he was 鈥渁sked to kill the study鈥� but did not. HHS didn鈥檛 immediately respond to that claim. The department said the Substance Abuse and Mental Health Services Administration wasn’t involved in the review or the clearance of the study published Tuesday, which evolved from the draft version with additional authors, analysis and policy recommendations.
Amanda Berger, senior vice president of science and research for the alcohol trade association the Distilled Spirits Council of the United States, said in an email to the AP that the congressional committee’s findings showed the study was 鈥渋rretrievably flawed.”
Findings support more forceful alcohol intake recommendation
The Trump administration earlier this year released new dietary guidelines that advised consuming 鈥渓ess alcohol for better overall health.鈥� The researchers said that they don’t dispute that advice but that their findings support a more detailed and forceful recommendation that current adult drinkers consume one drink or fewer a day.
鈥淚鈥檓 glad that they had a message that corresponds with our science, and that is that less is best,鈥� said Dr. Timothy Naimi, director of the University of Victoria鈥檚 Canadian Institute for Substance Use Research and one of the study鈥檚 authors. 鈥淏ut giving people quantity information is necessary to make a truly informative guideline.鈥�
The study differed from the other research commissioned by the government to help inform the dietary guidelines on the issue, which said moderate alcohol use was associated with a decreased risk of mortality from all causes but also an increased risk of some diseases.
Priscilla Martinez-Matyszczyk, one of the authors of the new study and a deputy scientific director at the Public Health Institute鈥檚 Alcohol Research Group, said their study didn鈥檛 look at mortality from all causes but instead examined mortality specifically attributed to alcohol to avoid confounding factors.
Martinez-Matyszczyk also addressed an issue raised by Centers for Medicare and Medicaid Services Administrator Dr. in his explanations of the new guidelines: that drinking is 鈥渁 social lubricant that brings people together鈥� and that even though not drinking is preferred, being social has health benefits.
鈥淚 don鈥檛 know of any studies that have teased out the social effect from the health effect,鈥� she said.
Research aligns with other recent findings
The new findings are 鈥渋n line with the latest science that basically shows less is better when it comes to health,鈥� Naimi said.
For example, a 2019 study in Lancet found that moderate drinking slightly raised the risk of stroke and high blood pressure and offered no protective effects on health.
Moderate drinking was once thought to have benefits for the heart, but better research methods have thrown cold water on that idea. Older studies compared groups of people by how much they drink instead of randomly assigning people to drink or not, so they couldn鈥檛 prove cause and effect. When researchers adjusted for things like education levels, income and health care access, the benefits tended to disappear.
About half of Americans age 12 or older had a drink in the past month, researchers said, making it the most commonly used addictive substance in the U.S. One drink is the equivalent of about one 12-ounce can of beer, a 5-ounce glass of wine or a shot of liquor.
