The Glycaemic Index (GI) ranks food items from 0 to 100 according to how quickly they are digested and enter your bloodstream. The higher the ranking of the food, the faster it raises your blood glucose levels. The Glycaemic Load (GL), on the other hand, considers the amount of carbohydrates (grams) in a single serving. For this reason, taking both GI and GL into consideration when selecting foods can help support an individual to maintain healthy blood sugar levels.
