Interesting Word - Pica

Pica is an eating disorder, which involves an abnormal compulsion to eat non-nutritive substances (such as paint, string, hair, animal droppings, insects, soil etc) for over a month.

(Yes, you will only be diagnosed as suffering from this if the compulsion persists for more than one month, and you have to be deemed developmentally able to determine whether an item is appropriate for consumption. So your average worm-eating 3-year-old does not suffer from this disorder.

I wonder if eating non-nutritive substances includes hot dogs?)
