Pica Means Magpie
Magpies4 are birds that will eat almost anything, whether it’s food or not. Some humans crave5 substances with no nutritional6 value. This eating disorder is called pica. Pica is Latin for magpie. People who suffer from pica have cravings for non-food substances, such as dirt, paper, or cigarette ashes. Most children outgrow7 this behaviour by the time they reach school age. If pica persists, it may be related to a psychological disorder that requires the help of a mental health worker. Pregnant women may also develop pica. Their cravings may stem from a lack of certain vitamins or minerals.
