What does geophagia mean?
Geophagia means the eating of earth, soil, clay, or other mineral-rich substances. The term occurs in both medical and anthropological contexts. Historically and in some cultures, the deliberate consumption of earth or clay has been associated with ceremonial, religious, or traditional healing practices. In modern clinical usage, geophagia is a specific form of pica, an eating disorder characterized by persistent consumption of substances that provide little nutritional value. It may attract attention because it can be associated with nutritional deficiencies, pregnancy, or other health concerns, although the practice has diverse meanings in different communities. Geophagia is also a precise term for an otherwise unusual behavior: it distinguishes eating the earth itself from eating ordinary food that happens to contain trace minerals. The word is useful in medical literature, cultural history, and discussions of traditional food practices because it identifies this specific practice without implying that every instance has the same social or medical significance.
