Question: What is a Carbohydrate?
Answer:
Carbohydrates include foods composed of starches, sugar and/or fiber. They are the most common source of energy found in food. Most carbohydrates break down into glucose (a specific type of sugar).
Examples of carbohydrates are: table sugar, fruit, milk, grains and vegetables.
Proteins and fats make up the other two main sources of energy. They do not break down into glucose.
