You mentioned that Muscle Structure is low glycemic. The only reason for a product to use maltodextrin is to avoid listing sugar on the label. I guess I'll be staying away from maltodextrin. From the beginning we set a low glycemic criteria for Muscle Structure TM , so it would not raise fattening insulin levels. As you know, the glycemic index is the measure of speed carbohydrates enter the bloodstream.
Many factors can influence how fast or slow carbohydrates are absorbed.
Protein, fiber and fat slow down the rate carbohydrates are absorbed and therefore positively influence glycemic index. Fructose is very low glycemic. It's only 23 on the glycemic index. The reason for this is that fructose must be converted by the liver before it can be used as blood sugar. That's why energy levels derived from fructose can more readily be sustained because it doesn't cause a rapid increase in blood sugar.
