I would like to know too. I love fruit too and in the summer I love to eat frozen grapes (!) yummy like ice cream.
It seems I've read that fruit (fructose), even though it isn't a processed carb, is still a simple carb and gets into the blood stream relatively fast. Not like white bread or sugar fast, because of all the fiber, but still pretty fast. Since fruit is all carb and doesn't provide a lasting effect on the blood sugar, and trying to keep your carbs about 45%, I would treat fruit like a treat. I try and keep my carbs at about that, 45-50%, and find it pretty hard to do.
