Carbohydrate and calories: it is not what we used to think.

The majority of our diet consists of carbohydrates. Carbohydrates may be glycemic, which can be broken down and turned into simple glucose molecules quickly, or non-glycemic, which are not turned into sugar until they reach the large intestine. The glycemic index tells us how quickly the food we eat is turned into sugar and the glycemic load will give us absolute amounts of sugar introduced into the body by a food.
