Pica (disorder)

	Pica
		Pica is most common in people with developmental disabilities, including autism and mental retardation, and in children between the ages of 2 and 3.
		One theory to explain pica is that in some cultures, eating clay or dirt may help relieve nausea (and therefore, morning sickness), control diarrhea, increase salivation, remove toxins, and alter odor or taste perception; some people actually claim to enjoy the taste and texture of dirt or clay.
		And some psychological theories explain pica as a behavioral response to stress or an indication that the individual has an oral fixation (is comforted by having things in his or her mouth).
