geophagous

Geophagous refers to the practice of eating earth, soil, or clay. This behavior is observed in various animal species, including humans, primates, birds, and insects. In many cultures, geophagy has a long history and is often associated with specific dietary practices, medicinal uses, or cultural rituals.

In humans, geophagy can occur for a variety of reasons. It is sometimes linked to nutritional deficiencies, particularly iron deficiency anemia, where the consumption of clay may provide essential minerals. Pregnant women in some societies also engage in geophagy, a practice known as pica, which may be related to cravings or an attempt to alleviate nausea. Psychologically, geophagy can also be a compulsive behavior.

The geological material consumed is often specific, with certain types of clay or soil being preferred over others. These preferred materials may have a lower concentration of toxins and a higher mineral content. Despite its prevalence, geophagy carries potential health risks, including the ingestion of parasites, heavy metals, and other harmful substances present in the soil. Scientific research continues to explore the nutritional, cultural, and physiological aspects of this widespread practice.
