PICA
Pica is an eating disorder in which a person eats things not usually considered food. Young kids often put non-food items (like grass or toys) in their mouths because they're curious about the world around them. Pica can be caused by many things, such as autism, low iron, pregnancy, Celiac disease, etc.
Diagnostic Criteria
A. Persistent eating of nonnutritive, nonfood substances over a period of at least 1 month.
B. The eating of nonnutritive, nonfood substances is inappropriate to the developmental level of the individual.
C. The eating behavior is not part of a culturally supported or socially normative practice.
D. If the eating behavior occurs in the context of another mental disorder (e.g., intellectual disability [intellectual developmental disorder], autism spectrum disorder, schizophrenia) or medical condition (including pregnancy), it is sufficiently severe to warrant additional clinical attention.
