The term "pica" to describe craving and chewing substances that have no nutritional value - such as ice, clay, cornstarch or paper. Craving and chewing ice is often associated with iron deficiency anemia - it may be associated with other nutritional problems.It's not known why some people with iron deficiency anemia crave and chew ice. Results from one study suggest it may be because of ice's pain-relieving properties, since some people with iron deficiency anemia experience tongue pain and inflammation (glossitis). researchers also found that ice has a new and better taste to some people who are iron deficient.

In some individuals, pica is a sign of emotional problems, such as stress, obsessive-compulsive disorder or a developmental disorder.

A thorough medical evaluation can help determine if pica is due to an underlying medical condition. If the cause of pica is an emotional or developmental issue, cognitive behavioral therapy may be helpful.
