Fructose acts differently in the human body though, its worse than normal sugars. Its only more recently, relatively that the impacts of different sugars are properly being understood. eg http://treeoflifecenterus.com/fructose-and-diabetes/ "Contrary to glucose, fructose creates a high concentration of fats and lipoproteins in the body and contributes to unhealthy lipid profiles. One major lipid increase with fructose is the triglycerides. It also converts to activated glycerol 3 phosphate (g-3-p), which is needed to convert free fatty acids into triglycerides. The more g-3-p one has, the more fat one can store. It also increases the activated APOB100, a primary lipoprotein that carries cholesterol to blood vessels and leads to fatty deposits. It decreases the high-density lipoproteins, which help take pathogenic cholesterol away from the vessels and back to the liver."
