Could a single glass of wine a day be the key to a healthier heart? A recent study by the University of Barcelona suggests it might be. Researchers found that “light to moderate” wine consumption significantly lowers the risk of major heart problems, potentially surpassing the effectiveness of some medications.

The secret lies in moderation. Drinking more than one glass a day eliminates the protective effects, highlighting the importance of self-control.

Over a five-year period, 1,232 individuals following a Mediterranean diet—but with an elevated risk of cardiovascular issues—were monitored. Using a urine test to detect tartaric acid, a compound linked to wine intake, scientists accurately measured participants’ consumption, making this study more reliable than earlier research.

Professor Ramon Estruch, who led the research, discovered that those who drank between half a glass and one glass of wine daily lowered their heart risk by 50% compared to non-drinkers. Even occasional drinkers, consuming less than one glass per week, reduced their risk by 38%. However, exceeding the one-glass limit offered no added protection.

Published in the European Heart Journal, the findings highlight wine’s unique potential. “The 50% reduction in risk surpasses the benefits of certain medications, such as statins,” Prof. Estruch explained. He also stressed that moderate drinking should start from the mid-30s and that women should consume only half the amount of men, ideally with meals.

The magic ingredient? Antioxidants found in grapes, which support heart and blood vessel health. Among all wine types, red wine stands out as the healthiest choice, thanks to its higher antioxidant levels.
