I've read about this condition. It is called Pica. Pica is the term used to describe the intense craving for – and eating of – non-food items. Pica is the Latin word for magpie and I suppose because magpies are known to eat pretty much anything. It is a worldwide phenomenon that is pretty common during pregnancy. No one knows what causes these unusual cravings, but a combination of biochemical, psychological, and cultural factors may be at work. In some studies, pica has been linked to iron deficiency ­– even though none of the craved items contain a significant amount of iron. There is some research suggesting that iron-deficiency anemia is associated with these strange cravings. http://www.babycenter.com/404_what-causes-pica-craving-and-consuming-non-food-items-during_1186643.bc
