Green potato skins (which I find to be rare) I avoid, along with avocado skins and pits...but mine get potatoes, the occasional bit of avocado innards, apple seeds, an odd orange. Most of it, they eat. Some they leave and it gets composted in. Never any health issues.
Oh, and apple pulp (from cider making) by the bucket, full of seeds.
