I don't believe different sugars are processed differently. I do thing that release mechanisms are different in, for example, corn vs corn syrup. The "extra stuff" you get with corn mediates how fast a body can absorb the sugar, the container needs to be broken down. So, in some sense, yes, all sugars are the same. The delivery system can change the rate of absorption though. *

* I have no proof of this. I'm making an uneducated guess that the insulin spikes aren't as steep or high with sweet fruits and vegetables compared with a spoon full of sugar.
