#4. Eating Dirt
Eating dirt (geophagia) is a genuine disorder that came into the spotlight after we saw video clips of Kristie Spinuzza crunching on rocks on TLC’s show “My Strange Addiction”. Geophagia can be a result of a severe nutritional deficiency of iron and calcium, or some kind of a psychological disorder. If allowed to go unchecked, it can lead to lead poisoning and parasitosis.
