Glycemic Load ( GL )
What Is Glycemic Load?
Similar to glycemic index (GI), glycemic load (GL) is a measurement which ranks the impact of food carbohydrates on blood glucose levels.
However the key difference between GI and glycemic load is that glycemic load reflects a specific foods glycemic index and portion size.
In essence glycemic load takes into account both the quality and quantity of the foods carbohydrates.
Glycemic Load Formula
GL = GI / 100 x CHO* (grams) per serving CHO = carbohydrate content
For example, using the formula to calculate the glycemic load of a medium sized apple which has 15 grams of carbohydrate, gives a GL of 6:
40 /100 x 15 = 6
