- glycemic Index
The glycemic index is a numeric system that ranks how quickly the body converts various foods into glucose. Foods are ranked on a scale of 0 to 100 depending on how they affect blood sugar levels once eaten. A GI rating of 55 and under is considered low on the index, while a rating of 56 to 69 is medium, and a rating of 70 or above is high. Simple carbohydrates are converted into glucose quickly and thus have high GI ratings.
