The Department of Health (UK) recommends that we should drink about 1.2 litres of fluid every day. This works out to be about six 200ml or eight 150ml glasses.
The total amount of fluid we lose each day and need to replace is in fact greater than this – about 2.5 litres – but we get 1 litre of the fluid we need from food and the body recovers 0.3 litres from chemical reactions in our cells. The rest needs to be taken from drinks.
All drinks count, but water, milk and fruit juices are the healthiest.
It is best to avoid alcoholic drinks.Try to avoid sugary soft and fizzy drinks that can be high in added sugars. These can be high in calories and bad for teeth.
