Most public health guidance on alcohol focuses on how much you drink. The UK Chief Medical Officers' advice is straightforward: no more than 14 units per week, spread across three or more days, for both men and women. But a large new study drawing on UK data suggests the picture may be more complicated - that the type of alcohol consumed matters significantly, particularly at lower levels of intake, where wine and spirits appear to carry quite different mortality risks.

What the study found

Recent research analysed alcohol consumption and mortality outcomes among 340,924 British adults who participated in the UK Biobank study between 2006 and 2022. Participants were followed for more than 13 years on average and grouped into consumption categories based on grams of pure alcohol consumed per day and week, with different thresholds for men and women.

At high levels of intake - defined as more than around three standard drinks per day for men, and more than one and a half for women - the risks were significant and consistent regardless of beverage type. Compared with never or occasional drinkers, heavy drinkers were 24% more likely to die from any cause, 36% more likely to die from cancer, and 14% more likely to die from heart disease.

The more novel finding emerged at low to moderate levels of consumption, where the type of beverage produced notably different results. Among moderate wine drinkers, the risk of dying from cardiovascular disease was 21% lower than in never or occasional drinkers. By contrast, even low consumption of spirits, beer or cider was associated with a 9% higher risk of cardiovascular death compared with drinking never or occasionally.

"Our findings help clarify previously mixed evidence on low to moderate alcohol consumption," said senior author Dr Zhangling Chen. "The health risks of alcohol depend not only on the amount of alcohol consumed, but also on the type of beverage."

Why the wine finding is complicated

Before drawing conclusions from the wine result, it is worth understanding why researchers - including the study's own authors - treat it with caution.

The team offer two explanations for why moderate wine consumption is associated with better cardiovascular outcomes. The first is biological: red wine contains polyphenols and antioxidants that may have beneficial effects on cardiovascular health. The second is sociological - and harder to adjust away. Wine in Britain and most Western countries is disproportionately consumed by people who already have healthier diets, higher incomes, and more health-conscious lifestyles. It is also more commonly drunk with meals, which affects how alcohol is metabolised. Spirits, beer and cider, meanwhile, were associated with lower overall diet quality and other lifestyle risk factors in this study.

The researchers adjusted for socioeconomic status, lifestyle factors, cardiometabolic markers, and family history of disease. But even with rigorous adjustment, observational studies of this kind cannot fully disentangle the effects of the drink from the effects of everything else that tends to go alongside it.

The researchers themselves acknowledge this - and call for high-quality randomised controlled trials to better understand the mechanisms involved. This study shows an association; it does not prove that wine protects the heart.

Why this matters for people in Britain

The UK has a serious and worsening alcohol problem, which makes research like this particularly relevant. In 2023, 10,473 people in the UK died from causes directly attributable to alcohol - the highest number on record, according to the Office for National Statistics.

In England alone, alcohol-specific deaths reached 8,274, a figure 42% higher than in 2019 and a record high since data collection began in 2006.

Against that backdrop, one in four people in England still drink above the CMO's 14-unit guideline. And according to the 2024 Drinkaware Monitor, only 17% of UK adults can correctly identify 14 units as the weekly limit - meaning most people have no clear reference point for assessing their own consumption. To note, the 14-unit guideline is equivalent to around six medium glasses of wine (175ml) or six pints of 4% beer per week.

What the research means practically

There are three things worth taking away from this research. First, the finding that high alcohol intake is harmful holds regardless of what you drink - no type of alcohol is a safe route to heavy consumption. Second, the difference between wine and other beverages at lower intake levels is a genuine signal in a very large dataset, but is unlikely to reflect the polyphenols alone. Lifestyle, diet, and socioeconomic factors do much of the explanatory work, and should not be mistaken for a licence to drink wine freely. Third, for anyone who drinks regularly and isn't sure how their intake measures up: the CMO's 14-unit guideline remains the most straightforward benchmark in the UK, and the evidence from this study reinforces that exceeding it meaningfully comes with real health costs.
