The long-standing debate over the health benefits of moderate wine consumption has gained new momentum, thanks to fresh research from Spain that may provide good news for wine lovers.
A study led by Professor Ramón Estruch from the University of Barcelona and the Hospital Clínico de Barcelona suggests that drinking a small to moderate amount of wine, particularly as part of a Mediterranean diet, significantly reduces the risk of cardiovascular events, especially in individuals at high risk of heart disease. The study, published in the European Heart Journal, found that consuming between half a glass and one glass of wine daily can lower the likelihood of serious cardiovascular issues by as much as 50%.
“This study demonstrates the importance of moderate wine consumption within a healthy dietary pattern, such as the Mediterranean diet,” Professor Estruch explained. “Until now, we believed that 20% of the effects of the Mediterranean diet could be attributed to moderate wine consumption. However, these results suggest the effect may be even greater.”
The study also revealed that even light wine consumption, defined as one glass per week to less than half a glass per day, offers a 38% reduction in cardiovascular risk. However, the benefits diminish when consumption exceeds one glass a day, reinforcing the need for moderation.
Unlike many previous studies, which relied on self-reported data, this research used a more precise method to measure wine intake by testing for tartaric acid, a chemical found in wine, in participants’ urine. “By measuring tartaric acid in urine, together with food and drink questionnaires, we were able to obtain a much more accurate measurement of wine consumption,” Estruch said. “Our findings show a far greater protective effect than previously observed, with a 50% reduction in risk—much higher than some drugs, such as statins.”
However, while the results are promising, Professor Estruch cautioned that the study focused on 1,232 elderly individuals living in Mediterranean countries who were at high risk for cardiovascular disease. “The results may not be applicable to other populations,” he noted. He also emphasized that the protective effects of moderate wine consumption are most evident from the age of 35-40. Women, Estruch added, should consume no more than half the recommended amount for men, and wine should always be consumed with meals.
In an accompanying editorial, Professor Giovanni de Gaetano from IRCCS NEUROMED in Italy praised the study for introducing urinary tartaric acid as a reliable biomarker for wine consumption. “The study represents an important step forward in our understanding of the complex relationship between wine consumption and cardiovascular health,” he said.
De Gaetano also stressed that while moderate wine consumption appears to have cardiovascular benefits, excessive drinking still carries risks. “This work supports the idea that light to moderate wine consumption can be part of a heart-healthy diet,” he said. “However, it also underscores the importance of moderation.”
As the debate over alcohol’s role in health continues, one thing is clear: when consumed responsibly and as part of a balanced Mediterranean diet, a daily glass of wine may be more than just a pleasant indulgence—it could offer real benefits for heart health.
