Pica: Pica is the ingestion of non-food materials, or substances with little or no nutritional value. Pagophagia is considered to be a type of pica - it is specifically the excessive or compulsive ingestion of ice. This is not simply enjoying ice in your beverages - it is a compulsive need or drive to chew on and ingest ice. Interestingly, it is sometimes an outward sign of anemia.
