What does geophagia refer to?

Geophagia refers to the practice of eating soil or clay. This behavior has been observed in various cultures and is often attributed to nutritional deficiencies or cultural practices. Individuals might consume soil to obtain minerals not adequately covered in their diet, such as iron or calcium, or as a remedy for gastrointestinal disorders. This phenomenon is particularly noted among certain populations where the practice is part of traditional medicine or cultural rituals.

In contrast, consuming raw plants pertains to a different dietary practice that focuses on the intake of uncooked vegetation, while drinking unfiltered water involves hydration practices that may pose health risks due to contaminants. Chewing on wood relates to behaviors observed in some animal species or specific human habits but does not encompass the concept of geophagia. Therefore, the definition that clearly identifies the consumption of soil or clay accurately captures the essence of geophagia.
