A study into the effects of alcohol consumption which showed that even moderate drinking has damaging effects on the brain has sparked interest about how exactly moderate drinking is defined.
There is a lot of confusion about the measurement of alcohol intake, in part because units are defined differently in Ireland from the UK – our measures tend to be bigger!
In Ireland, a standard drink, or unit, has about 10 grams of pure alcohol in it.
Examples of standard drinks include a half-pint of beer, a pub measure of spirits or a small glass of wine. So, a pint of beer or a large glass of wine is two units, not one. A bottle of wine contains about seven standard drinks, or units.
