A U.S. analysis in the Journal of Studies on Alcohol and Drugs links even one alcoholic drink per day to higher risks of cancer, cardiovascular disease, liver cirrhosis and injury. Commissioned by HHS and based on U.S. data, researchers recommended tightening guidance to no more than one drink daily for both sexes. The study's commissioner says he faced opposition and was later dismissed; HHS and USDA say the work was reviewed as part of the broader evidence base. Recent guideline changes that removed numeric drink limits have prompted debate about industry influence and public-health clarity.
Study Finds Even One Daily Drink Raises Cancer, Heart and Injury Risks — Sparks Debate Over U.S. Guidelines

A U.S.-based analysis published in the Journal of Studies on Alcohol and Drugs concludes that alcohol consumption, including levels commonly considered “moderate,” is associated with higher risks of illness and death. The researchers report that a single alcoholic drink per day was linked to increased mortality and morbidity, and that drinking more than one drink per occasion produced progressively greater risks for breast cancer, cardiovascular disease and injury.
Key Findings
The study, commissioned by the Department of Health and Human Services and using only U.S. data, found that both men and women who consumed one drink daily showed higher deaths from liver cirrhosis, oral and esophageal cancers, and injuries. For women specifically, a single daily drink was associated with increased mortality from breast and liver cancer. The authors conclude that U.S. guidance should be tightened to recommend no more than one drink per day for both men and women.
Controversy Over Review and Release
Robert M. Vincent, the official who commissioned the study, wrote in an accompanying editorial that he faced "sustained opposition to a federally authorized scientific effort that produced evidence at odds with powerful commercial interests," and has said he was later dismissed as part of a reduction in force. He told The Associated Press he was "asked to kill the study." A direct quote attributed to Vincent appears in the editorial and media reports.

Health and Human Services (HHS) and the U.S. Department of Agriculture (USDA) have denied that the study was shelved. HHS spokeswoman Emily Hilliard said the department reviewed the paper alongside the broader scientific record and followed the established process for developing the 2025–2030 Dietary Guidelines for Americans. HHS also noted that the Substance Abuse and Mental Health Services Administration (SAMHSA) was not involved in review or clearance of the published paper.
Guideline Changes and Industry Questions
Earlier this year, federal guidance was loosened: the updated recommendations removed specific numeric drink limits for men and women and dropped an explicit warning that even moderate drinking raises cancer and cardiovascular risks. Dr. Mehmet Oz, administrator of the Centers for Medicare and Medicaid Services (CMS), described alcohol as "a social lubricant that brings people together" while saying abstaining is healthiest.
Reporting from The New York Times and other outlets has raised questions about possible conflicts of interest: some panelists advising the guideline review from the National Academies of Sciences, Engineering, and Medicine (NASEM) reportedly had financial ties to the alcohol industry. Critics say that removing clear numeric guidance reduces the public's ability to make informed decisions about risk.

What Experts Say
One study author, Dr. Timothy Naimi, director of the University of Victoria's Canadian Institute for Substance Use Research, told PBS that while he welcomes the general message that "less is best," concrete quantity guidance is necessary to make public health recommendations informative and actionable.
