Geophagy is the practice of eating earthy or soil-like substances such as clay, and chalk. It exists in animals in the wild and also in humans, most often in rural or preindustrial societies among children and pregnant women. Human geophagy may be related to pica, a classified eating disorder in the DSM-IV characterized by abnormal cravings for nonfood items.
