Glucose is, as best we can tell, just fine. Obviously glucose is fine at some level -- as you say, the body uses it internally. But that doesn't mean that there wouldn't still be a problem if we only got rid of the fructose we're eating and replaced it with glucose. The quantity of glucose we would then be ingesting with each meal would be quite large, and that might have other negative consequences -- mediated, perhaps, by the even larger insulin release that would be triggered. But I'm only speculating. I haven't come across any research that bears on this question. If you have, I'd like to see it.
