Units are a clever way to help you know just how strong your drink is.
One unit of alcohol is 10 ml or 8g of pure alcohol. This equals a third of a pint of cider.
Alcoholic drinks are made by fermenting and distilling natural starch and sugar.
Cider can contain lots of calories. For instance, one pint of cider with 4.5% ABV can contain 210 calories which is the same as a sugar donut.
Cider like any kind of alcohol, can stimulate the appetite and make calorific post-pub food like kebab and chips look more appealing.
How much is too much?
The UK Chief Medical Officer advises that people should not regularly drink more than the low risk drinking guidelines (14 units a week for men & women).
