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.
