The UK reduced its guideline limit to a "low risk" 14 units for both sexes in 2016, equivalent to six 175ml glasses of wine, six pints of beer or cider, or 14 single gin and tonics.
Researchers also found there is still a small benefit to drinking, The Guardian said.
This likelihood of an early death increases the more alcohol is consumed, the Cambridge-led researchers said.

Professor Naveed Sattar, co-author of the study and an expert in cardiovascular science at Glasgow University, said: "This study provides clear evidence to support lowering the recommended limits of alcohol consumption in many countries around the world".
But the study's lead author, Angela Wood of the University of Cambridge, noted that the benefit must be balanced against the higher risk associated with other serious, and possibly fatal, heart ailments, The Guardian said. It does reduce the chance of a non-fatal heart attack. Consuming two bacon sandwiches a week or sitting watching a hour of television per day is statistically more risky for long-term health. So it's as if each unit above guidelines is taking, on average, about 15 minutes of life, about the same as a cigarette.
'Of course it's up to individuals whether they think this is worthwhile'.
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.More news: Jamaal Lascelles 'Focused' on Newcastle Amid Chelsea Rumours, Says Rafa Benitez
In fact, an global study by the Lancet medical journal found that drinking alcohol multiple times a week may shorten your lifespan. Scientists found a 40-year-old exceeding the benchmark of 100g of pure alcohol, around five drinks a week, had their life expectancy shortened by six months.
Tim Chico, professor of cardiovascular medicine at the University of Sheffield, said smokers lost on average 10 years of life.
The good news is we don't have to stop drinking.
'This is a massive and very impressive study. "It estimates that, compared to those who only drink a little, people who drink at the current United Kingdom guidelines suffer no overall harm in terms of death rates, and have 20% fewer heart attacks". It did not take into account the possibility of mental disorders such as dementia, which could accompany the other health problems drinkers incur. "We should always remember that alcohol guidelines should act as a limit, not a target, and try to drink well below this threshold". "Nonetheless, the findings ought to be widely disseminated and they should provoke informed public and professional debate".More news: British Premier Theresa May defends 'right and legal' Syria strikes
