No alcohol safe to drink, global study confirms

Bad news for those who enjoy what they think is a healthy glass of wine a day.

A large new global study published in the Lancet has confirmed that there is no safe level of alcohol consumption.

The researchers admit moderate drinking may protect against heart disease but found that the risk of cancer and other diseases outweighs these protections.

A study author said its findings were the most significant to date because of the range of factors considered.

How risky is moderate drinking?

The Global Burden of Disease study looked at levels of alcohol use and its health effects in 195 countries, including the UK, between 1990 and 2016.

Analyzing data from 15 to 95-year-olds, the researchers compared people who did not drink at all with those who had one alcoholic drink a day.

They found that out of 100,000 non-drinkers, 914 would develop an alcohol-related health problem such as cancer or suffer an injury.

But an extra four people would be affected if they drank one alcoholic drink a day.

For people who had two alcoholic drinks a day, 63 more developed a condition within a year and for those who consumed five drinks every day, there was an increase of 338 people, who developed a health problem.

One of the study authors, Prof Sonia Saxena, a researcher at Imperial College London and a practicing GP, said: “One drink a day does represent a small increased risk, but adjust that to the UK population as a whole and it represents a far bigger number, and most people are not drinking just one drink a day.”

The lead author of the study Dr Max Griswold, at the Institute for Health Metrics and Evaluation (IHME), University of Washington, said: “Previous studies have found a protective effect of alcohol on some conditions, but we found that the combined health risks associated with alcohol increases with any amount of alcohol.

“The strong association between alcohol consumption and the risk of cancer, injuries, and infectious diseases offset the protective effects for heart disease in our study.

“Although the health risks associated with alcohol start off being small with one drink a day, they then rise rapidly as people drink more.”

Prof Saxena said the study was the most important study ever conducted on the subject.

She explained: “This study goes further than others by considering a number of factors including alcohol sales, self-reported data on the amount of alcohol drank, abstinence, tourism data and the levels of illicit trade and home brewing.”

A drink was defined as 10g of alcohol, which equates to a small glass of wine, a can or bottle of beer, or a shot of spirits. In the UK one unit is 8g of alcohol. Around the world, one in three people are thought to drink alcohol and it is linked to nearly a tenth of all deaths in those aged 15 to 49.
