I’m more referring to when a random person experiences a random craving for something they’ve had before.
Does that generally point to something you’ve had before that unknowingly satisfied a deficiency and which your body tacitly took note of?
I notice it sometimes, like
Beef = i “need” a burger (I’m a skinny dude, beef is not a common staple for me)
Fruit: i need juice or actual berries in yogurt for a smoothie or parfait
Something something African children sometimes eat dirt for iron as crazy as it sounds. Thats definitely related to what I’m talking about
That’s called “pica” and is NOT related to any deficiencies.

It’s not pica, they sell soil or clay in markets for consumption, usually for pregnancies:

Thaťs different from child searching for the dirt and eating it by itself - those cravings serve no dietary purpose.
