Agave nectar is 100% pure, unrefined nectar from this fruit. It has one of the lowest G.I. (glycemic index) values so that means that you won't get high peaks in your blood sugar level like you get with cane sugar. Because of the slow, steady increase in the blood sugar level required in diabetics, it is ideal for everybody including diabetics. Diabetics can adjust their short acting insulin depending the pattern they see on their meter.
