Are the vitamins in the skin of an apple?

Tricky question...

Generally speaking it's a good idea to keep the skins on your fruits and vegetables--but not because they're a great source of vitamins and minerals. Quite the contrary.

In potatoes, for instance, the skin, which is a dark corky layer called the "periderm," consists mostly of dead cells filled with a waxy, largely vitaminless substance whose chief function is to protect the potato's insides.
