It's difficult to digest some fruit peelings. It can also be a choking hazard since they can be hard to chew if the fruit is raw. I peeled apples and pears. In fact, John still doesn't like to eat apple peelings. I think if you are cooking them, making apple sauce for example, you can puree the peeling with the fruit. Just make sure you wash the fruit really well to remove any residue of pesticides that may stll be on the peeling.
