All carbohydrate foods behave differently in our bodies. The Glycemic Index, (GI), ranks all these types of carbohydrates from 0 to 100 according to their effect on our blood glucose levels. It is only based on foods high in carbohydrates and is about quality of that food and not quantity.
Creating long-term health for yourself by using the Glycemic Index is very simple. It is just a case of choosing the low GI foods that will release glucose into your blood stream at a slow pace, little by little and for a longer period of time. This keeps your energy levels balanced also makes you feel fuller for longer between meals.
Some carbohydrates act in a different way and are quickly broken down in the intestines rapidly raising blood glucose levels. The foods with these types of carbohydrates should be avoided; these have a high Glycemic Index.
