Study challenges belief that moderate alcohol consumption shields against obesity and type 2 diabetes
Moderate alcohol consumption does not provide protection against conditions such as obesity and type 2 diabetes, according to a recent study, challenging the long-debated notion of potential health benefits associated with light to moderate drinking.
The study investigated whether modest alcohol intake had any positive effects on health—a subject that has divided experts. Researchers analysed data on alcohol consumption from over 400,000 participants and discovered a higher risk of obesity and type 2 diabetes among individuals who consumed more than 14 drinks per week. Notably, this link was more pronounced in women than in men.
Dr. Tianyuan Lu of McGill University in Québec commented on the findings, stating, “Previous research has suggested that moderate drinkers may be less susceptible to developing obesity or diabetes compared to non-drinkers and heavy drinkers. However, our study indicates that even light-to-moderate alcohol consumption, defined as no more than one standard drink per day, does not safeguard against obesity and type 2 diabetes in the general population.”
The study’s results revealed that heavy drinking was associated with increased measures of obesity, such as body mass index, waist-to-hip ratio, and fat mass, as well as an elevated risk of type 2 diabetes.
Importantly, the study did not find any evidence of improved health outcomes related to moderate alcohol consumption in individuals who consumed seven or fewer alcoholic drinks per week.
Dr. Lu concluded by highlighting the significance of the research in promoting awareness of the risks associated with alcohol consumption. The study’s findings aim to inform future guidelines and recommendations regarding alcohol use, with the hope of encouraging healthier behaviours as alternatives to drinking.
