Drinking and Mortality Risk: What the Largest Study Yet Reveals

A landmark study tracking more than 340,000 adults over 13 years has found that alcohol raises the risk of death, and no amount is entirely safe. Specifically, researchers presented the findings at the American College of Cardiology’s Annual Scientific Session in March 2026, drawing on data from the UK Biobank. As a result, the study adds strong new evidence that cutting alcohol, or avoiding it completely, is the wisest choice for long-term health.

The Numbers That Show How Alcohol and Death Risk Are Linked

The scale of this research gives it real authority. In total, researchers tracked alcohol consumption habits and mortality outcomes among 340,924 British adults enrolled between 2006 and 2022. Furthermore, they followed health outcomes for more than 13 years on average.

The results make a sobering case against heavy drinking. Compared with people who drank rarely or never, those with high alcohol consumption were:

• 24% more likely to die from any cause
• 36% more likely to die from cancer
• 14% more likely to die from heart disease

Notably, these figures apply to men drinking more than 40 grams of pure alcohol daily, which is roughly three standard drinks. For women, the threshold was more than 20 grams, or around one and a half standard drinks.

Even Low Intake Raises Drinking and Mortality Risk

Importantly, the study shows that drinking and mortality risk does not begin only at heavy consumption levels. For spirits, beer, and cider, even low to moderate intake carried a 9% higher risk of dying from cardiovascular disease compared with rare or non-drinkers.

Moreover, senior author Zhangling Chen, MD, PhD, professor at the Second Xiangya Hospital, Central South University in China, made the stakes plain. For people with chronic diseases or cardiovascular conditions, the alcohol and death risk could climb even higher.

The research team noted that wine drinkers at low to moderate levels showed different patterns in the data. They linked this partly to compounds such as polyphenols found in red wine and partly to broader lifestyle differences among wine drinkers. Even so, the core finding holds across all drink types: alcohol carries measurable risk at every level of consumption.

How Researchers Conducted the Study

To carry out the analysis, the research team grouped participants into four intake categories based on their drinking and mortality risk profiles. These ranged from never or occasional drinkers through to high daily consumers. They then adjusted the data to account for age, sex, socioeconomic status, lifestyle factors, and family history of diabetes, cardiovascular disease, and cancer.

Consequently, lead researcher Chen said the findings clarify previously mixed evidence on low to moderate consumption. In particular, guidance should reflect not just how much people drink, but what they drink and the habits that surround it.

However, the team acknowledged that observational studies carry inherent limitations. Randomised trials would provide stronger proof of cause and effect. In addition, participants self-reported their alcohol intake at the start of the study, so any later changes in drinking behaviour went untracked. Similarly, UK Biobank participants tend to be healthier than the wider population, which may narrow how broadly the results apply.

Nevertheless, a sample of over 340,000 people followed for more than a decade gives the alcohol and death risk findings considerable weight.

A Clear Warning for Anyone Who Drinks

Overall, public awareness of alcohol and death risk has grown sharply in recent years. As a result, major health bodies worldwide now move away from the idea that moderate drinking offers any net benefit.

Therefore, this study supports that shift. The data point in one direction: the less alcohol consumed, the lower the risk. For anyone thinking seriously about their long-term health, the evidence here is hard to set aside.
