Studies reveal moderate drinking may offer some health benefits but also highlight serious risks, including cancer, dementia, and fatal falls.
As Dry January wraps up, the long-standing debate over whether alcohol is ever beneficial—or solely harmful—continues to divide experts.
For years, research has highlighted conflicting narratives about alcohol’s impact on health. Early studies suggested a “J-curve” effect, indicating that moderate drinkers might experience certain health benefits compared to non-drinkers. In one such study, individuals consuming about half a drink per day exhibited the lowest risk of death. Men who consumed up to four drinks daily, and women who had up to two, were found to have a lower risk of mortality than abstainers. However, the risk increased sharply for individuals who exceeded these thresholds.
More recent findings have challenged this perspective. A 2024 study conducted by researchers at the Shenzhen University of Advanced Technology in China established a linear relationship between alcohol consumption and brain health. The study concluded that as alcohol intake rises, so does the risk of cognitive decline, including dementia. Researchers emphasized that there is no “safe” level of alcohol consumption when it comes to protecting brain health.
The ongoing debate underscores the need for individuals to weigh potential health benefits against the well-documented risks of alcohol, which range from cancer and neurological damage to fatal accidents. As Dry January comes to a close, many are left pondering whether a permanent shift away from alcohol might be the healthier choice.
