Researchers followed 340,924 UK Biobank participants for an average of 13.4 years, examining total alcohol consumption as well as intake of wine, beer, cider and spirits. The analysis recorded 22,381 deaths and assessed mortality from cardiovascular disease, cancer and other causes.
Heavy alcohol consumption carried clear risks regardless of beverage. Participants in the highest intake category had a 24% greater risk of death from any cause than people who never drank or consumed alcohol only occasionally. Their cancer mortality risk was 36% higher, while cardiovascular mortality was 14% higher.
The pattern changed at lower levels of consumption. Low and moderate intake of beer, cider and spirits was associated with higher mortality across several categories. Comparable amounts of wine were associated with lower mortality, including a pronounced difference in deaths from cardiovascular disease.
Moderate wine drinkers had a 21% lower risk of cardiovascular death compared with people who never drank or drank only occasionally. By contrast, even low consumption of beer, cider or spirits was associated with a 9% higher risk of cardiovascular death.
Researchers classified participants consuming no more than 20 grams of alcohol a week as never or occasional drinkers. Low consumption ranged from more than 20 grams a week to 20 grams a day for men and 10 grams a day for women.
Moderate consumption was defined as more than 20 grams and up to 40 grams a day for men, and more than 10 grams and up to 20 grams for women. Consumption above those thresholds was considered high.
A standard alcoholic drink contains roughly 14 grams of pure alcohol, although serving sizes and alcohol concentration vary between countries and products.
The findings do not establish that wine itself prevents cardiovascular disease. The research was observational, meaning differences between groups may have been influenced by factors that could not be fully separated from drinking behaviour.
Wine drinkers often differ from consumers of beer and spirits in diet, income, education, smoking habits and other aspects of lifestyle. Wine is also more commonly consumed with meals, potentially linking it with different eating patterns and drinking behaviour.
Researchers adjusted the analysis for demographic characteristics, socioeconomic status, lifestyle, cardiometabolic factors and family histories of cardiovascular disease, diabetes and cancer. Residual differences between groups may nevertheless remain.
Compounds found particularly in red wine are another possible explanation. Polyphenols and other antioxidants have been studied for potential effects on blood vessels, inflammation and cardiovascular function. The study, however, does not demonstrate that these substances caused the lower mortality observed among wine drinkers.
The cancer findings also complicate any interpretation of wine as a healthier alcoholic beverage. Moderate overall alcohol consumption was associated with an 11% higher risk of cancer death, while heavier consumption produced substantially greater risks.
Moderate-to-high intake of beer, cider and spirits, together with high wine consumption, was associated with elevated mortality from several site-specific cancers. These included cancers affecting the head and neck, respiratory and gastrointestinal systems, liver and gallbladder, blood, breast and reproductive organs.
Alcohol itself is a recognised carcinogen, and health authorities have stressed that cancer risk can rise even at comparatively low consumption levels. That means an observed cardiovascular association with wine cannot be treated as evidence that people should begin drinking for health reasons.
Another limitation is that alcohol consumption was based largely on participants reporting their drinking habits when they joined the study. Changes in beverage choice, drinking frequency or quantity during more than a decade of follow-up were therefore not fully captured.
