A wine a day WON’T kill you, experts now claim in fresh twist to decades-long row over health risks of moderate drinking
- Women may be able to enjoy wine daily without risk of dying early jumping
- And men may be able to drink almost two large glasses of wine a day
Enjoying a tipple in moderation may not significantly increase your risk of an early death, a study suggests.
Women may be able to indulge in a large glass of wine a day, on average, without their risk of dying early significantly increasing, based on a new scientific review by researchers in Canada.
Men may be able to drink an average of almost two large glasses of wine a day without a higher risk of death than non-drinkers.
The findings come from a review of 107 studies including more than 4.8 million people.
However the review authors say the studies included have multiple flaws, and they would still advise that moderate amounts of alcohol carry small risks for serious diseases such as cancer.

Researchers compared the odds of dying among non-drinkers in the studies to the odds of dying for drinkers with low, medium, high or very high alcohol consumption.
Women who drank moderately, falling into the low alcohol consumption group, were found to have no significant increase in their risk of death compared to female non-drinkers.
These women drank less than 25 grams of alcohol a day – approximately three units in the UK, which is the equivalent of one large glass of wine, or three small measures of gin.
Men were not significantly more likely to die than non-drinkers if they drank a low or medium amount.
This included men who drank less than 45 grams of alcohol a day – about five-and-a-half units a day in the UK, which works out as about three 330ml bottles of lager a day on average, or not too far off two large glasses of wine.

However the researchers say the results should not be used for safe drinking guidelines, because of the study flaws.
In 86 of the studies looked at, non-drinkers included former drinkers, who may have stopped drinking because it had already led to health issues, which is likely to have skewed the results.
Drinkers may also wrongly appear as healthy as non-drinkers because some of those non-drinkers are in fact unwell, which is why they don’t consume alcohol.
The review, published in the journal JAMA Network Open, found the risk of an early death did become significantly higher past a certain threshold of alcohol, which was lower for women than men.
For men drinking 45 to 64 grams of alcohol, which is up to eight units a day, or four pints of low-strength beer, the risk of an early death was found to be 15 per cent higher than for non-drinkers.
The risk of an early death was 21 per cent higher for women drinking 25 to 44 grams of alcohol a day, which means the equivalent of more than one large glass of wine.
Study co-author Dr Tim Stockwell, former director of the Canadian Institute for Substance Use Research, said: ‘This review was set up to look at flaws in studies and how they bias estimates of alcohol’s health risks.
‘For example, over 80 per cent of the studies in the review counted people who gave up alcohol due to ill health as abstainers.
‘Compensating for these types of mistake greatly reduced the appearance of health benefits from moderate drinking.
‘Stronger studies are needed to determine exact levels of drinking at which men and women are at an increased risk of premature death.’
