<i>ANY starch is broken down rapidly in the small intestine and absorbed as sugar.</i><p>That may be an oversimplification. Lustig, in the lecture mentioned by the GP, shows that there are big differences between how the body metabolizes glucose and fructose. If these differences are significant enough (Lustig's thesis is that they are), then it isn't a "false distinction" to single out sugar/HFCS from other carbohydrates.
