Unless you have a Zinc deficiency, then eating certain kinds of clay can be nutritious (look up the research by Ananda S Prasad). This habit of geophagia is fairly common in villages in Iran, where their diet would otherwise be deficient. I think these people definitely should be informed that the syndrome occurring in their male population of severe iron-deficiency anemia, hypogonadism, dwarfism, hepatosplenomegaly and geophagia is caused by Zinc deficiency and how their natural diet can be supplemented.SHISHKABOB said:that's not entirely true: if I tell you that eating dirt is not a good idea compared to eating real food, that's not subjective at all
