Yeah, I was gonna say-- pureeing berries severely impacts dietary fiber, which in turn impacts glycemic index, since your body no longer has to work around nearly as much cellulose to get to the sugar. It's a physical process that has an impact on a chemical process. And of course you chew your food, but you can't chew anything nearly so fine as your blender does.
Here's a more concrete analogy-- sawdust is highly flammable. Many times more so than regular old wood. Why? Better oxygenation, higher surface area, lower per-unit thermal mass (which means less energy required to get a particular chip of wood to its combustion point).
