The glycemic index or GI measures the effect of carbohydrates on blood sugar levels. High GI indicates a faster breakdown of carbohydrates, and a rapid release of glucose into the bloodstream during digestion while low GI indicates a slower breakdown and therefore a more gradual release of glucose.
