The glycemic index is a rating of carbohydrates and their effect on blood sugar levels. The higher the glycemic index of a certain carbohydrate, the greater the blood sugar response after eating it. Consuming dietary fiber can lower the glycemic rating of carbohydrates. Carbohydrates are stored as glycogen in the liver and muscle tissue. Eating lower glycemic index carbohydrates can allow for a steady release of energy and help keep blood sugar levels stable.
Fruit provides a form of carbohydrate called fructose, which is a low glycemic carbohydrate.
