What does it mean when a person craves cornstarch?

A person who is craving cornstarch or other non-food items might be suffering from pica, according to the National Institutes of Health's MedlinePlus. Pica is a condition that can affect a pregnant woman; however, it is more commonly seen in young children.

Some cases of pica are thought to be the result of missing nutrients in the body. Instead of craving food items, the person craves foods that contain high amounts of the nutrients needed. For others, pica is a result of desiring a specific texture in the mouth. Speaking to a doctor about the cravings is advisable so the underlying cause might be determined.
