I’ve heard of glucose, but what is it?

grainsGlucose is a type of sugar and the main source of energy used by your body. Glucose comes from many kinds of foods called “carbohydrates”, such as cereal, bread, rice, pasta, and other grains, not just sugary foods. Dairy products, fruits, and vegetables all contain carbohydrates as well. Your body uses the glucose it needs and then stores the rest as “glycogen” in your liver and muscles.
