For decades, moderate alcohol consumption—typically defined as one to two drinks per day—was thought to provide certain protective benefits for heart health. However, the American Heart Association (AHA) has now issued a strong scientific statement saying that belief no longer holds up against emerging evidence. The AHA, along with many cardiologists in India, including those in Kolkata, are urging caution and reconsideration of alcohol's role in heart health.Rethinking the “Protective” MythAccording to the AHA statement released on June 9, new studies using improved research methods have cast doubt on earlier findings that suggested alcohol might reduce the risk of cardiovascular diseases like heart attacks or strokes. While some observational studies hinted at cardioprotective effects, experts now say the data lacks consistency and credibility.The idea that moderate drinking might lower the risk of certain heart conditions emerged from flawed or outdated studies, many of which didn’t adequately account for lifestyle, dietary patterns, or underlying health issues in participants.Complex and Controversial LinksThe relationship between alcohol and cardiovascular disease is far from straightforward. The AHA points out that alcohol use has long been linked with a range of heart-related conditions—including high blood pressure (hypertension), myocardial infarction (heart attack), arrhythmias, stroke, and heart failure. While excessive alcohol consumption has always been known to be harmful, even moderate intake may not be as safe as once believed.Cardiologists caution that no randomized controlled trial has definitively shown alcohol in any form to be beneficial for heart health. Claims that wine—especially red wine—may have positive effects apply only in very specific contexts, and do not justify broad public recommendations.When Moderation Isn’t EnoughExperts highlight that for certain individuals, particularly those with high blood pressure, reducing or even eliminating alcohol consumption may be the only safe course. This is because alcohol—even when consumed moderately—can aggravate hypertension and make it harder to control.There’s also uncertainty around stroke risk. While heavy drinking undeniably increases the likelihood of strokes, the impact of low to moderate drinking remains unclear due to conflicting data. This uncertainty challenges the assumption that light drinking is harmless.Addiction and Lifestyle RisksHealth professionals continue to warn that all forms of substance use, including alcohol and tobacco, contribute to lifestyle diseases and chronic health conditions. The 2020–2025 Dietary Guidelines for Americans recommend no more than two drinks a day for men and one for women. However, India’s revised Dietary Guidelines, prepared by the Indian Council for Medical Research and the National Institute of Nutrition, do not make any mention of alcohol at all—highlighting a gap in national-level public health messaging.The global burden of alcohol-related health issues is immense. The U.S. National Institutes of Health (NIH) estimated that alcohol-related conditions could cost the U.S. nearly $1.87 trillion between 2011 and 2050, equivalent to about 1.45% of the country’s GDP. The NIH also criticized the lack of clear public messaging, which has allowed myths about alcohol’s safety to persist for decades.In 2023, the World Health Organization (WHO) reinforced this warning. In a statement published in The Lancet Public Health, it declared that there is no safe level of alcohol consumption that does not affect health. WHO has also set a goal of reducing harmful alcohol use globally by 10% between 2013 and 2025.
