Try looking into rice syrup for a sweetner, I don't know about the glycemic index value for it, but it is quite nice. As well, stevia is a good sweetner. It supposedly doesn't alter blood sugar at all, so it is supposed to be good for diabetics. One acre of stevia is the equivalent of 28 acres of sugar! So basically one teaspoon is practically the equivalent of 1 cup of sugar! It comes in two forms, powder (green or white) and liquid, and one drop is all you need in your tea or coffee. It has an after taste like black licorice. So if you don't like black licorice, you won't like stevia!
