I have no idea on the science of it, but I like to keep in mind that fruits as we know them today aren't very natural. Sweet bananas are less than 200 years old; I'm pretty sure apples & grapes, etc., are all hybridized to be much bigger and sweeter than in nature, etc. So having one here and there is fine for me, but I don't want to go crazy with them, since that's really a relatively new (historically speaking) possibility and our bodies haven't adapted to it yet.
