This condition can be associated with nutritional deficiencies, mental health disorders, or developmental issues, and understanding it is important for those in the field of environmental health, as pica can have significant health implications due to the ingestion of harmful substances. Addressing pica typically involves identifying and treating any underlying causes, alongside educational efforts on appropriate dietary choices.
