New research suggests that moderate wine consumption may significantly lower the risk of heart attacks and strokes but experts urge caution about overindulgence.

A glass of wine a night may do more than complement your dinner—it could significantly lower the risk of heart attack and stroke, according to a new study. Researchers have found that moderate wine consumption, defined as one glass per night, can cut the risk of heart disease by nearly half.

The study, published in a leading medical journal, tracked the drinking habits and health outcomes of over 25,000 adults across a 10-year period. It revealed that participants who regularly consumed small amounts of wine were 48% less likely to experience cardiovascular events such as heart attacks or strokes compared to non-drinkers.

The researchers credit the heart-health benefits to compounds found in wine, particularly red wine, such as antioxidants and flavonoids. These compounds are known to reduce inflammation and improve blood vessel function, both of which play a critical role in preventing cardiovascular disease.

Dr Emma Carter, a cardiologist and co-author of the study, explained, “The key lies in moderation. A single glass of wine a night seems to offer protective benefits without introducing the risks associated with heavier drinking.”

Why Wine Works

Wine, particularly red wine, contains resveratrol, a powerful antioxidant found in the skins of grapes. Resveratrol has been linked to lower cholesterol levels and improved heart function, making it a favourite in heart health research.

The study also found that wine drinkers tended to adopt other heart-healthy behaviours, such as eating a balanced Mediterranean-style diet and engaging in regular exercise. Researchers believe these lifestyle factors likely enhance the cardiovascular benefits of moderate drinking.

Proceed with Caution

However, experts are quick to warn against overindulgence. Dr Carter emphasised, “The line between moderate and excessive drinking is razor-thin. While one glass of wine can be beneficial, drinking more than that can lead to serious health issues, including liver disease, high blood pressure, and an increased risk of certain cancers.”

The study further clarified that the benefits observed were specific to moderate wine drinkers. Those who drank spirits or consumed excessive amounts of alcohol did not experience the same cardiovascular advantages.

Health organisations remain cautious about promoting alcohol consumption as a health measure. They advise individuals who don’t already drink to avoid starting solely for perceived health benefits, as the risks can outweigh the rewards if not managed responsibly.

Balancing Act

For those who enjoy a nightly glass of wine, the findings are certainly welcome. “This is good news for people who already drink responsibly,” said Dr Carter. “But it’s essential to keep portions in check and to incorporate other heart-healthy habits, such as maintaining a balanced diet and staying active.”

While wine may offer a boost to heart health, experts continue to stress that no single factor can entirely eliminate the risk of cardiovascular disease. A combination of healthy habits, routine check-ups, and informed decisions is the best defence against heart issues.
