What exactly is a "glicemic index" (sp?)?!

Glycemic index. Glycemic index (GI) is a way to compare one food to another in terms of its ability to raise your blood sugars. It is based upon a specific amount of food eaten in isolation and thus can be affected when the same food is consumed as part of a meal. In general, it's thought that low GI foods are better especially for diabetics (and in preventing diabetes). Check out http://www.Glycemicindex.Com.
