This clay could influence the pH of the stomach acid and help to combat heartburn - many women in Africa eat a diet consisting mainly of maize, cassava and pulses. Soil contains clay, which binds toxins, in the same way as charcoal tablets combat diarrhea. ![]() However, the reason behind it could be quite different - and also quite multi-layered. Geophagy is a form of substance craving, just like a craving for chocolate or as a type of "reward." Says Kutalek: "These people often eat clay as a snack between meals and report that they could not do without it."

Consumption should definitely be reduced." The maximum limit is 155 µg. "And it is probable that there is a direct correlation with geophagy. By way of comparison, the lead concentration in newborns in Austria is much lower: on average we only find 13 µg of lead per litre," explain lead investigators Ruth Kutalek und Claudia Gundacker. Blood samples taken from the mother or from the baby's umbilical cord after birth showed significantly higher lead concentrations than those found in newborn babies in Austria, for example: "We found an average lead concentration of 60 µg of lead per litre of blood in newborn babies in the Democratic Republic of Congo.
