Types of sugar
Our sugar is also referred to as sucrose. It is made up of two basic components. Glucose comes from the carbohydrates that we eat. Our body changes them to energy and transports them into the bloodstream. Fructose occurs naturally, especially in fruits, vegetables and honey. When we eat an apple or orange fructose is changed into glucose and goes into our blood.
Lactose, or milk sugar, is found in dairy products. Some adults are not able to digest milk sugar and should not consume dairy products.
