Persistent eating of non-food substances

In medicine and psychiatry, pica is the persistent eating of substances with no nutritional value (earth, clay, starch, ice, and the like) beyond what is developmentally or culturally expected, and it is seen notably in pregnancy and in some nutritional deficiencies. Young's 2010 review in the Annual Review of Nutrition reconsiders the causes and significance of pica in pregnancy. The condition takes its name from the magpie (Pica), after the bird's indiscriminate appetite. The referent is a behavioural/clinical pattern of ingesting non-food, not a unit of type or a genus of bird, though it borrowed its name from the latter.[1]

Unit
