Some, but not most. There’s significant nutrition in the phloem (layer under the skin) which is not removed by peeling. And even the center has nutritional value. It is best to peel them just before using rather than let them sit around once peeled, since the peel protects them.
Medical argument against it actually, as you remove most of the healthy stuff.
