Dirt
Eating dirt is very common especially among children, but interestingly, it is common among adults as well. There is an interesting practice called Geophagia and it translates literally to “eating the earth” and its soil-like substances such as chalk. Eating dirt, however, can be very dangerous especially because of the chemicals and parasites it contains. In some cases though, if the soil is 100% organic and has not been treated with any chemicals, it is safe for human consumption.
