Guielines on alcohol consumption


With such a vast array of drinks and glass sizes available including shots, pint glasses and bottles; It is understandably easy to get confused about how many units are in your drink. Units are a simple way of expressing the quantity of pure alcohol within a drink. One unit equals 10ml or 8g of pure alcohol, which is approximately the amount of alcohol the average adult can process in an hour.

The NHS has recommended that men should not regularly drink more than four units per day, whilst women should avoid regularly drinking more than three units of alcohol per day. Further recommendations include avoiding alcohol for a minimum of forty-eight hours following a heavy drinking session.

It is imperative to understand that these are only ‘guidelines’ and that any amount of sustained alcohol consumption is likely to be destructive to both oral and general health in the long term.
