While this seems reasonable, and I whole-heartedly endorse your push for sources, it does call to mind a corn-industry sponsored commercial I saw a while back about HFCS that I found amusing. It said, "Sugar is sugar; your body can't tell the difference!" which sounded common-sensical buuut fructose, sucrose... well, lactose is a sugar too, and some of our bodies seems to be able to tell the difference there!

Of course, this isn't evidence one way or the other for the claim in question, really. Bad arguments for side A aren't arguments for side B - just hoping others find it as amusing as I did.
