This enables slow release of sugar into the blood stream, which would further ensure that your blood glucose levels are stable for a long period of time. Moreover, the glycemic index of raw oranges is just about 40-43. The Glycemic Index is a relative ranking of carbohydrate in foods according to how they affect blood glucose levels. Carbs with low GI value are digested, absorbed and metabolized slowly and cause a gradual rise in blood glucose. Diabetics are advised to include more low GI foods in their diets.
