Glycemic Numbers

The glycemic index measures the effects of the carbohydrate in a given food on blood glucose levels. Foods are ranked on a scale of 1 to 100. The higher the number, the more quickly a carbohydrate raises blood sugar. A more useful number is the glycemic load, which ranks food by both its glycemic index number and the amount of carbohydrate in an actual serving size of the food.
