Ive heard of the Glycemic Index. What is it?
The glycemic index is a listing of foods in the order those foods cause surges in insulin. Individuals are given equal amounts, usually half-cup portions, of a food. Their blood sugar is measured before and after. Then, an average is taken to determine the glycemic index of that food. The higher the number, the more the food causes surges of insulin in the blood stream. Low carb dieters try to stay on the lower half of the glycemic index. It can be confusing because there are two standards for the glycemic index: one using white bread as 100 and the other using glucose as 100.
