The Wall Street Journal recently reported on an old but revitalized controversy that could reshape America’s dietary guidelines for alcohol consumption. For years, conventional wisdom has suggested that moderate drinking—up to two drinks a day for men and one for women—might confer some health benefits. However, new research is challenging this belief, sparking a fierce debate among scientists and policymakers.
The Case Against Moderate Drinking
The latest findings from the Interagency Coordinating Committee on the Prevention of Underage Drinking (ICCPUD) highlight the risks associated with even low levels of alcohol consumption. According to the report, consuming more than seven drinks per week raises the risk of alcohol-related illnesses and injuries. For example, individuals consuming more than nine drinks weekly face a 1 in 100 risk of dying from such conditions.
The committee’s analysis, based on 56 scientific reviews, found that one drink per day increases the risk of liver cirrhosis, esophageal cancer, and oral cancer. While moderate alcohol use was linked to a lower risk of blood clot-related strokes, this benefit could be erased by binge drinking, even on rare occasions. “This study highlights the nuanced relationship between alcohol intake and health,” said Dr. Annie DePasquale, a family medicine physician. “While moderate consumption has often been framed as safe, the evidence increasingly shows that even low levels of alcohol can contribute to serious conditions.”
Cancer risks associated with drinking are particularly concerning. Researchers noted that the risk of developing cancers such as colorectal, breast, and esophageal cancer begins with any alcohol use, with women being especially vulnerable. As Kevin Shield, senior scientist at the Institute for Mental Health Policy Research, succinctly put it, “People shouldn’t be drinking for health reasons. There’s no evidence of it.”
The Case for Moderate Drinking
In contrast, a review by the National Academies of Sciences, Engineering, and Medicine (NASEM) suggests potential benefits of moderate alcohol consumption. Their research, which accounted for newer studies and removed biases from earlier data, found that moderate drinkers had a 16% lower risk of dying from any cause compared to non-drinkers. The study also linked moderate drinking to a reduced risk of cardiovascular death.
However, these benefits come with caveats. The same review found that moderate drinkers faced a 10% higher risk of breast cancer. Dr. Ned Calogne, chair of the NASEM committee, emphasized the complexity of the findings, noting that moderate drinking might appear beneficial due to confounding factors. For example, moderate drinkers often have higher incomes and healthier lifestyles overall. “It’s such a normal part of our culture that people who don’t drink, there’s something unique about them,” said Dr. Michael Siegel of Tufts University School of Medicine, who questions the validity of the supposed health benefits.
Weighing the Evidence
Both reports agree that the relationship between alcohol and health is highly complex. While moderate drinking may lower certain risks, it undeniably increases others, particularly cancer. Moreover, researchers caution that alcohol’s effects vary widely based on genetics, lifestyle, and drinking patterns. “Everyone will have to start thinking about their own level of risk that they’re willing to accept,” said Timothy Rebbeck, a cancer prevention researcher at Dana-Farber Cancer Institute.
What’s Next?
As U.S. officials prepare to update the Dietary Guidelines for Americans later this year, the stakes are high. The alcohol industry has rallied behind the NASEM’s findings, while many public health experts lean toward the ICCPUD’s stricter recommendations. Regardless of the outcome, individuals will need to carefully weigh the risks and benefits of their drinking habits.
In the end, the choice may come down to personal priorities. Is the occasional glass of wine worth the potential long-term risks? Or is the safer path to abstain altogether? The debate is far from settled, but one thing is clear: our understanding of alcohol’s impact on health continues to evolve.
