What Are Sugars? 
You can classify sugars into 2 groups.

1. Intrinsic sugars  (natural sugars)  where sugar is held inside the food molecule in foods like fresh fruits.

2. Extrinsic Sugars or sugars outside of the food cells.

Extrinsic sugars can be further broken down into a) milk sugars  & b) non milk sugars.

a) Milk Sugars (also natural sugars) are in milk and milk products and cause less tooth decay. In Fact eating some cheese after a meal can help reduce tooth decay – you still have to brush twice a day !!!

b) Non Milk Sugars – also called added sugars or free sugars are the greatest concern for teeth. These have no nutritional value and add unnecessary kilojoules. Examples are glucose or sucrose (table sugar) and are often added to foods we buy and also in honey, syrups and fruit juices.
