Whereas with high-glycemic foods blood sugar rises quickly, as does insulin which lowers blood sugar. When the blood sugar drops you will feel hungry. A common misconception is that simple carbohydrates, such as fructose, will automatically have a high-glycemic index. While complex carbohydrates will have a low-glycemic index, because it is assumed it will take more time to digest a complex versus a simple carbohydrate. There is no obvious, simple relationship between the type of carbohydrate and its glycemic index.
Several factors affect glycemic index.
The type of sugar does have some impact. Fructose has a lower glycemic index than sucrose or glucose. Carbohydrates high in fiber, such as many vegetables, tend to have lower glycemic indexes. No doubt glycemic index will continue to be a topic of discussion amongst fitness enthusiasts as well as dietitians. Inc. Site by FX Media, Inc.
