Early deaths rose when more than 100g per week, which is five to six glasses of wine or pints of beer, was consumed.
Study participants who said they consumed more than seven drinks per week had higher overall rates of mortality.
"The paper estimates a 40-year-old drinking four units a day above the guidelines has roughly two years lower life expectancy, which is around a twentieth of their remaining life".
The big worldwide study supports the new United Kingdom recommended limits of a maximum of 14 units a week for both men and women, which were fiercely contested when introduced by England's chief medical officer, Dame Sally Davies, in 2016.
Lead author Dr Angela Wood said: 'The key message of this research is that if you already drink alcohol, drinking less may help you live longer and lower your risk of several cardiovascular conditions'.
It is now the sixth biggest cause of illness for those in their 50s and 60s, with numbers rising. US recommendations state that men shouldn't consume more than 14 standard drinks per week, which is almost twice the limit proposed in this new study.More news: Trump attorney Michael Cohen says he's "not worried" by Federal Bureau of Investigation raids

Between 10 and 18 beverages a week could take off one to two years of your life expectancy, and if you have more than 18 alcoholic drinks a week, you could lose between four to five years. "This is a serious wakeup call for many countries", said Professor Jeremy Pearson, Associate Medical Director at the British Heart Foundation, which helped fund the research. Slugging down more than five drinks a week increases your risk of stroke, heart failure, fatal aneurysm, or death. "Later, when production lines are more automated, the production of flax reinforced and production costs reduced, our bottle may involve products with lower added value".
There is still a small benefit to drinking, which has been much flagged in the past.
The findings were roughly the same for both men and women, suggesting recommended levels for both sexes should be the same. "We should always remember that alcohol guidelines should act as a limit, not a target, and try to drink well below this threshold".
The risks for a 40-year-old of drinking over the recommended daily limit were comparable to smoking, said one leading scientist. That's about the same risk as from a cigarette, David Spiegelhalter, Winton professor for the public understanding of risk at the University of Cambridge, explained in a statement.
'But above two units a day, the death rates steadily climb.
According to the 2015-2020 Dietary Guidelines, a standard drink in the U.S.is a 12 fl oz. can of regular (5 percent alcohol) beer, a 5 fl oz. glass of 12 percent wine or a 1.5 fl oz. shot of a 40-percent distilled spirit like vodka or whiskey. Consuming two bacon sandwiches a week or sitting watching a hour of television per day is statistically more unsafe for long-term health.
