Our diet should include some sugary foods, such as cakes and biscuits and maybe the odd sugary drink.
Some foods have natual sugars, such as fruit and milk. We do not have to restrict this type of sugar.
We do need small amounts of salt in our bodys, to make it work properly. Adults should have no more than 6gramms a day.
Eating to much salt can lead to high blood pressure.
