practice of eating earth or soil-like substrates such as clay or chalk
Geophagia, also known as geophagy, is the intentional practice of consuming earth or soil-like substances such as clay, chalk, or termite mounds. It is a behavioural adaptation that occurs in many non-human animals and has been documented in more than 100 primate species. Geophagy in non-human primates is primarily used for protection from parasites, to provide mineral supplements and to help metabolize toxic compounds from leaves. Geophagy also occurs in humans and is most commonly reported among children and pregnant women.
