Teetotallers' mental health may also be worse. A Norwegian survey from 2009 of more than 40,000 people found that non-drinkers suffer higher levels of anxiety and depression than drinkers.
The happiest people were very light drinkers - those who averaged two glasses of wine, a bottle of beer, or a shot of spirits per week. Non-drinkers may be more gloomy as they miss out on the companionship of social drinking, suggested research leader Dr Eystein Stordal, from the Norwegian University of Science and Technology.
Crucially, all these benefits of alcohol are associated with low to moderate drinking. Habitual heavy drinking clearly carries numerous physical dangers.
Even moderate consumers who engage in binge drinking have double the odds of dying within the next 20 years in comparison with moderate drinkers of the same age who don't, according to recent research in the journal Alcoholism: Clinical and Experimental Research.
A U.S. study in 2011 found that having just three to six glasses of wine or any alcoholic drink per week raises a woman's risk of breast cancer. The risk was 15 per cent greater than for teetotal women.
Because of such concerns, Anne Lingford-Hughes, professor of addiction biology at Imperial College London, says she welcomes the new NICE (National Institute for Health and Care Excellence) guidance to reduce the amount we drink.
"The physical benefit of moderate drinking is only for the cardiovascular system," she says. "For everything else, zero consumption is the only thing that means zero risk."
Dr James Nicholls, director of research at the health charity Alcohol Research UK, said mild drinking's protective effects for common cardiovascular problems have to be set against the danger of cancers that are comparatively rare. "The issue with the new NICE guidance is that it is going away from guidelines on moderate levels of drinking and going towards abstinence as the goal," he says.
"The risk involved in setting the limits too low is that people may ignore them completely. The term 'all things in moderation' may be a good way ahead, both with consumption and with guidance."
