New research links even low alcohol consumption to cancer, heart disease, and premature death

Key Points:

• A new study published in the Journal of Studies on Alcohol and Drugs finds that even moderate alcohol consumption increases the risk of premature death, disability, and chronic diseases such as cancer and heart disease, with no observed protective health effects at low drinking levels.
• Researchers analyzed over 7,200 scientific articles and applied risk estimates to national health data, concluding that drinking two alcoholic drinks per day substantially elevates the risk of alcohol-related premature death.
• The study challenges previous beliefs about alcohol’s health benefits, showing that potential protective effects against ischemic heart disease and stroke are outweighed by increased risks of cancer and other chronic diseases at consumption levels above seven drinks per week.
• Unlike the current U.S. Dietary Guidelines, which advise limiting alcohol without specifying safe amounts, this research provides a clearer quantitative framework, indicating increased health risks begin above one drink per day for both men and women.
• An editorial accompanying the study notes that despite its relevance to the 2025–2030 Dietary Guidelines development, the study’s findings were sidelined, highlighting tensions in public health policy discussions on alcohol consumption.
