Eating disorder makes girl crave metal

A young Nebraska girl is battling an extremely rare eating disorder.

Mackenzie Sisson is just like any other eleven year old, only she's addicted to metal."She can see a staple lying on the floor in a classroom, in the carpet. She can find metals in the rocks that you can never see," explained Mackenzie's mother Patricia.
After five years of searching for answers, the Monroe-Myer Institute in Omaha diagnosed her with pica, an extremely rare eating disorder. Mackenzie also has Tourette's Syndrome.
