One system for classifying carbohydrates is the glycemic index. The glycemic index ranks foods on how they affect blood sugar level by measuring how much the blood sugar increases after one eats. For example, white bread is digested quickly into glucose, causing blood sugar to spike quickly. Therefore white bread has a high glycemic index number. In contrast, brown rice is digested more slowly, causing a lower, more gentle change in blood sugar. It therefore has a lower glycemic index number.
