Study Links Wine Consumption to Lower Mortality Risk

A recent study presented at the American College of Cardiology’s Annual Scientific Session indicates that low to moderate wine consumption may be associated with a lower risk of mortality compared to other alcoholic beverages. The research analyzed health data from over 340,000 adults in Britain, gathered through the UK Biobank study, which spans from 2006 to 2022.

The study categorized participants into four drinking groups: never or occasional drinkers (approximately 1.5 drinks per week), low drinkers (up to 1.5 drinks daily for men and 0.75 drinks for women), moderate drinkers (up to 3 drinks daily for men and 1.5 drinks for women), and heavy drinkers (more than 3 drinks daily for men and more than 1.5 drinks for women). The findings revealed that heavy drinkers had a 36% increased risk of dying from cancer and a 14% increased risk of dying from heart disease.

Notably, moderate wine drinkers exhibited a 21% lower risk of dying from cardiovascular disease compared to those who never or occasionally consumed alcohol. In contrast, low to moderate consumption of spirits, beer, or cider was linked to a 9% higher risk of mortality.

The study emphasizes that the health risks associated with alcohol consumption are influenced not only by the quantity consumed but also by the type of beverage. Zhangling Chen, MD, PhD, the senior author of the study, noted that the findings clarify previously inconsistent evidence regarding low to moderate alcohol consumption.

Researchers cautioned that the observed benefits of wine consumption may be influenced by lifestyle factors. Wine is often consumed with food and is more likely to be associated with individuals who maintain healthier diets and behaviors. Additionally, wine contains compounds such as polyphenols and antioxidants, which may contribute positively to health outcomes.

While the study presents compelling data, it also acknowledges the limitations of current knowledge regarding alcohol consumption and health risks. Critics may argue that the correlation between wine consumption and lower mortality does not imply causation, and further research is necessary to fully understand the implications of different types of alcoholic beverages on health.

The Hill

The study suggests that moderate wine consumption may offer health benefits, particularly in reducing the risk of cardiovascular disease, while other alcoholic beverages may pose higher mortality risks. As the research continues to evolve, it highlights the importance of considering both the type of alcohol and associated lifestyle factors when evaluating the health impacts of alcohol consumption.

• “Taken together, these factors suggest that the type of alcohol, how it is consumed and the associated lifestyle behaviors all contribute to the observed differences in mortality risk,” — Zhangling Chen, MD, PhD
