Tag: Clay cravings

According to a 2025 study in Tanzania, geophagia—the practice of eating soil or clay—was prevalent in 27% of pregnant women surveyed. An underlying cause for craving for clay soil is often linked to nutritional deficiencies, a recognized form of the eating disorder known as pica.

According to the Cleveland Clinic, pica, a condition involving the eating of non-food items, is relatively common, with nutritional deficiencies being one of the leading reasons why people crave clay and other substances.
