Even the occasional drink is harmful to health, according to the largest and most detailed research carried out on the effects of alcohol, which suggests governments should think of advising people to abstain completely. The uncompromising message comes from the authors of the Global Burden of Diseases study, a rolling project based at the University of Washington, in Seattle, which produces the most comprehensive data on the causes of illness and death in the world.
Alcohol, says their report published in the Lancet medical journal, led to 2.8 million deaths in 2016. It was the leading risk factor for premature mortality and disability in the 15 to 49 age group, accounting for 20% of deaths. Current alcohol drinking habits pose "dire ramifications for future population health in the absence of policy action today", says the paper. "Alcohol use contributes to health loss from many causes and exacts its toll across the lifespan, particularly among men." Most national guidelines suggest there are health benefits to one or two glasses of wine or beer a day, they say. "Our results show that the safest level of drinking is none."
The study was carried out by researchers at the Institute of Health Metrics and Evaluation (IHME), who investigated levels of alcohol consumption and health effects in 195 countries between 1990 to 2016. They used data from 694 studies to work out how common drinking was and from 592 studies including 28 million people worldwide to work out the health risks.
