Moderate Wine Consumption Linked to Slower Biological Aging in Men, Italian Study Finds

Researchers observe reduced biological age in men following a Mediterranean diet with daily wine, but see no effect in women

A new study from Italy has found that moderate wine consumption, especially as part of a Mediterranean diet, may slow biological aging in men. The research, published in the International Journal of Public Health, analyzed data from 22,495 adults and divided participants into five groups based on their drinking habits: abstainers, former drinkers, moderate drinkers according to national guidelines, moderate drinkers following Mediterranean Diet criteria, and heavy drinkers.

The study focused on the difference between chronological age—the number of years a person has lived—and biological age, which reflects the condition of cells and organs and is considered a better indicator of health risks and longevity. Researchers found that men who drank one or two glasses of wine per day, roughly 125 to 500 milliliters, as part of a Mediterranean diet showed slower biological aging compared to those who did not drink wine. The effect was most pronounced after about one to two glasses per day, with biological age reduced by an average of 0.34 years.

However, the benefits were only observed in men who drank moderately. The study did not find a significant difference in biological aging among women who consumed similar amounts of wine. Researchers suggest this may be due to differences in how men and women metabolize alcohol and the stronger physiological effects experienced by women.

The Mediterranean diet is known for its emphasis on vegetables, healthy fats such as olive oil, and moderate wine consumption. Previous studies have linked this diet to various cardiovascular benefits and slower rates of aging. The researchers believe that bioactive compounds in wine, such as polyphenols—antioxidants that help reduce inflammation—may play a role in slowing biological aging.

Despite these findings, the study’s authors caution that excessive wine or alcohol consumption cancels out any positive effects. They also note that while moderate wine intake may be associated with slower aging in men, the results do not prove causation. More research is needed to understand how lifestyle habits like diet and alcohol consumption affect the aging process.

Federal guidelines on alcohol consumption have shifted over time. While some recommendations suggest moderate drinking can support social relationships, there is still debate among health experts about whether any amount of alcohol is truly beneficial for health. Most agree that individual responses to alcohol vary widely and that abstaining from alcohol remains the safest choice for many people.

The Italian cohort used in this study is known as Moli-sani, which has provided valuable insights into the relationship between diet, lifestyle factors, and health outcomes over several years. This latest research adds to ongoing discussions about the potential risks and benefits of moderate wine consumption within a balanced diet.

Healthcare professionals continue to advise moderation and emphasize that no single food or beverage guarantees healthy aging. While an occasional glass of wine may offer some benefit for certain individuals, it should be considered within the broader context of overall lifestyle choices.
