Characterized by the consumption of materials such as soil, chalk, and hair, pica is a disorder involving an appetite for non-nutritive substances or an abnormal compulsion to eat foodstuffs that are usually ingredients, such as flour or starch. Such eating behaviors have been observed in people of all ages but are only termed pica if they persist for more than one month in persons deemed developmentally able to determine whether an item is appropriate for consumption.
