Orange Peels: Good Source of...?

We always knew Max was a funny kid. Not like creepy-weird strange funny. Just a kid who does his own thing when and where he pleases. This is a classic example. We bought these great oranges from Costco, they were so sweet and yummy. So of course we offered some to Maddox. Being the pickiest kid in the whole world, he turned his nose up at them after one little nibble. Tyler and I scarfed them down (of course) and left the peels on a plate. We didn't pay much attention to it until we saw this:

And they are a good source of... ?? Does anyone know? Fiber? Calcium? Indigestion? (Oh, and this is also the face he makes when we ask him to smile or push (when he's pooping -- sometimes he needs a little encouragement)).

He's actually wearing my gray knit cap with flowers on it and playing a spoon like a guitar while singing.
