A second adaptive theory is that geophagy provides protection from enterotoxins or parasites either by direct binding or decreased permeability of the gut wall.

A large review of geophagy in humans & animals came to the conclusion that human geophagy is protective.

RFK Jr’s worm has publicly said that “geophagy” should be an alternative to traditional nutrition in our public schools.

This #openscience paper that used camera collars to gather natural history of Andean bears is among the coolest papers I have read!

Through the eyes of the Andean bear: Camera collar insights into the life of a threatened South American Ursid
This study used a camera-equipped GPS collar on a male Andean bear in southeastern Peru, revealing rare behaviors like courtship, novel diets, and geophagy. These findings from the Kosñipata Valley p...

Back in eastern Madagascar, Indri is also focused on eating, but her snack of choice right now is... soil? This behavior, which scientists call geophagy, is common in indris, helping them maintain their microbiome & manage the toxins of a leafy diet (Borruso et al 2021).#2025MMM

In geophagy, soil & clay ingested inhibit iron absorption perpetuating a vicious cycle.

In plumbophagy (lead) iron deficiency increases lead absorption exacerbating lead toxicity.

Burton’s line (lead sulfide deposition between teeth & gums) may be seen.

Studies show resolution of pagophagy (ice) w/iron repletion but this finding is less consistent w/other substances.

The substances ingested often don’t contain iron, arguing against this adaptive theory.

Geophagy is more common w/white clay than iron rich red clay.

Support for this includes
✨accompanied gastrointestinal distress & ingestion of toxic chemicals
✨clay adsorption
✨high prevalence in tropics
✨high prevalence when protection needed (ie pregnancy)

In contrast, animals derive protection AND micronutrients from geophagy

I got an A+ in my Geophagy exam.

I'm still trying to process that.

we got this text shortly after a grocery run that cost $90 more than the same grocery run did in 2022. if we had children we’d be soft launching geophagy and you get to pick the color of your shovel.
electric company sends an urgent text message to let us know our usage has doubled since last month. this is good. this is sustainable.

Bite the fingernail and
you can taste unwashed
clay, unintentional geophagy.
Sure I could bathe, but the
gritty creaminess would
be lost. Consume conflict
and civilizations and
excavation, and they
metabolize to bone and
skin. Your integrity
becomes eons,
free ones.

Geophagy is common in human and non-human primates! (I wrote a paper on this in grad school and got quoted in a national news article...)

Macaque monkeys in Gibraltar are being fed so much junk food by tourists that they're resorting to eating soil and clay to soothe their tummies. Poor little guys. @sciam.bsky.social

Larimar makes me mad that i cant do geophagy.
They look like such tasty lil candified beach water drops
Amazing polished Larimar crystals found only in the Dominican Republic.

Barbary macaques in Gibraltar have developed a surprising habit - eating soil 🐒

Researchers found this behaviour to be especially common in summer, when tourist numbers (and snack-sharing) peak.
