Natural versus added sugar
Unfortunately food labels in the UK currently don't distinguish between natural sugars, like lactose in milk or natural sugars in fruit, and added sugar.
All fruit and some vegetables store energy naturally as sugar. Fruit and vegetables are an important source of vitamins, minerals, antioxidants and fibre. Therefore nutritional advice is to cut down on added sugar, but not to avoid fruit, vegetables and milk as a way of reducing sugar intake. Many breakfast cereals, especially muesli, contain dried fruit as well as wholegrains, seeds and nuts; contributing towards a healthy diet, despite the fact they may appear to have a relatively high overall sugar content.
As a rule of thumb, a useful way to check for added sugar is to look at the ingredient list on food packages and avoid foods where ‘added sugar’ appears high up on the ingredients list.
