Glycemic Load (GL)
Glycemic load, like GI (Glycemic Index), is a way of ranking carbohydrate containing foods. However, the glycemic load takes into account both the GI of the food and the amount of carbohydrate in a serve of the food.
GL= (GI X carbohydrate per serve (g)) / 100
A GL of 20 or more is high, a GL of 11 to 19 inclusive is medium, and a GL of 10 or less is low.
Because it takes into account the amount of carbohydrate in a food, the GL is best used to determine the overall impact on blood glucose levels of foods of different types.
