They Properly Eat Chalk And Call It Medicine

By Warren Hamilton Category: Culinary Chaos 7th June 2026

Funny thing: humans will eat some strange stuff when hungry or worried. Geophagy is the proper name for it - chewing or swallowing earth, clay, or a neat lump called calabash chalk. It is a thing across West Africa, parts of the American South, and sprinkled here and there worldwide. Pregnant women, kids, folk with an upset tum - they reach for it like you might grab a packet of crisps.

People do it for sensible reasons. Some clays, like kaolin or bentonite, bind acids and nasty bits in the gut. They can feel soothing. Other times it is about getting minerals - iron, calcium - or sticking to custom. Birds in the Amazon eat clay to neutralise plant poisons. Humans copied that idea ages ago, only with less feathered dignity.

Now, it sounds mental. You offered to nibble a lump of dirt, you would laugh. But it can actually behave like a medicine in tiny doses. Doctors call compulsive eating of nonfood things pica, because medicine likes tidy words. The tradeoff is where the chaos starts. Calabash chalk and some clays sometimes arrive with bonus heavy metals: lead, arsenic. Studies in West Africa found elevated lead levels in people who chewed this stuff. So what was meant to steady a stomach can make you proper ill.

I once had a friend hand me a smidge while I was on the road years ago and told me it was 'good for the baby'. I almost choked on principle. I nibbled it like a man testing a biscuit that looks a bit off. Taste? Earthy, dry, like someone microwaved a field. The funny bit is the seriousness: whole markets sell the stuff, midwives recommend it, and outsiders go pale at the sight.

So the weird fact is tidy: eating clay is an old, global survival trick that actually helps in some ways and ruins people in others. It sits in that gap between practical and daft. Which, frankly, is where most brilliant things in life live.
