A major health study has found that consuming two alcoholic drinks a day is associated with a substantially higher lifetime risk of dying from alcohol-related causes. The findings challenge the belief that moderate drinking is necessarily safe and suggest that the overall health risks may outweigh any benefits previously attributed to low levels of alcohol consumption.
Daily Consumption Linked to Higher Lifetime Risk
Researchers estimated that people consuming an average of 14 alcoholic drinks per week face approximately a 1 in 25 lifetime risk of death from alcohol-related causes. By comparison, consuming up to seven drinks per week was associated with much smaller increases in risk for most health conditions.
The analysis combined evidence from more than 7,200 scientific publications with national health data to estimate the relationship between alcohol consumption, disease and premature death. Researchers examined a range of outcomes, including liver disease, cardiovascular conditions, several types of cancer and injuries.
The figures represent population-level estimates rather than predictions of what will happen to any particular individual.
Researchers Find No Overall Protective Effect
The study also examined the longstanding belief that small amounts of alcohol may protect heart health. Although some analyses have suggested possible benefits for certain cardiovascular conditions, researchers found no significant overall protective effect when a wider range of health outcomes was considered.
The potential advantages observed for some conditions were outweighed by risks linked to other diseases, including cancer and liver problems. The researchers also noted that individual outcomes can vary according to genetics, lifestyle and drinking patterns.
What the Findings Mean for Public Health
The results provide a more detailed assessment of how alcohol-related risks change as consumption increases. They may also help inform future public health recommendations by offering estimates of long-term risk rather than relying on broad descriptions such as moderate drinking.
The findings do not predict an individual’s personal health outcome, but they reinforce the importance of recognising alcohol-related risks. Overall, the study found no clear basis for considering alcohol consumption beneficial to health across all major outcomes.
