What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

I was baffled no one wrote here WHY anyone would do this. Here's the answer from the article:
Thanks for citing this, but it still doesn't explain why this custom has developed.
I can't speak for these specific people, but I know that eating clay can absorb toxins, like the kinds of poisons plants make to stop you eating them. There's also potentially mineral supplementation and introduction of beneficial bacteria.
But it's not very safe to eat dirt in modern times because we've poisoned a lot of the soil with various substances. You can buy edible dirt which is known to be safe.
Wait, what?
The most likely explanation is that kaolinite clay is known to reduce nausea and diarrhea.

I compost and a common practice is to throw a handful of your native soil into your pile when you start it, to inoculate it with local soil bacteria. Bacteria do most of the work in an active compost pile.
I wonder if people were getting some kind of gut flora benefit from this.
I wonder this exact thing, given that soil is a living organism full of beneficial bacteria and other organic materials. The food we eat consumes it, takes what it needs, and then we do the same.
I find it also interesting that while the article claims this is a cultural thing vs. being done for heath benefits, I’d argue it became cultural because of a universal understanding of health benefits.
Now I’m not saying this is some long lost concept that is the missing key to fix all our ills, however I can see how consuming soil was an integral part of maintaining gut health and boosting immunity way before we understood how those systems work.
Depending on the composition of the soil it might also have antiparasitic properties.
Or they could be beneficial parasites, like that episode of the space show.
What rational reason is there for people to eat cereal for breakfast?
Cereal was designed to prevent masturbation.
That's why I rub out a fat one first and THEN eat the cereal.
I'd say it does a pretty good job. I hardly ever jack off while eating Cheerios in the morning.
Then why are they called Apple Jacks?!
Cream of Wheat, not cream of meat.
There's always a reason, but it doesn't need to be entirely rational. Kellogg was a nut, but that's a different topic, no?
Yeah pour it in the trousers!
That's true for a lot of customs.
Pretty much all customs are culturally transmitted - that’s kind of the definition. But they’re not necessarily totally arbitrary either - there is often some other information that can be added beyond “they have learned to do it.”
Oh I agree.
The cause of the cultural behavior usually has a purpose though.
Yeah, but not necessarily one that is still relevant or even ever actually worked towards whatever goal there originally was. Cultural inertia is like that.
So it probably at some point had a purpose, but that purpose (whatever it was) might or might not apply any more or even be total nonsense.
We need to bring back sun god sacrifices, then. Maybe that's why global warming and Stacy won't go out with me.
In clinic, this is called pica.
Dirt is full of streptomyces species and spores. It's why dirt smells like dirt. Those species produce most of our antibiotics.
