AFAIK, dirt and feces are rich in cobalamine (vitamine B₁₂), which is otherwise scarcely available in non-animal sources.

Calling it a "disorder" and "largely non-nutritive" seems a bit broad, when it could be satisfying a particular need. Even though eating feces might not be a good idea and more serious examples do seem useless and damaging.

I also thought it odd that the article (or perhaps broader academic community) characterizes these behaviors as necessarily disordered. There seems to be a logic to it.
