Define edible
If you eat it and it doesn't kill you or make you sick within 24 hours
That's Exactly why I ask! Lol, under that definition you just proposed (doesn't quickly make sick) rocks or slow acting poisons are edible. Derive nutrition? Won't kill you? But another train of logic might be "is able to be chewed/digested by body - in which case poisons are edible - once.
Gold is a common food decoration and considered edible, but of no nutritional value.
Most plants are slow acting poisons, they don't want to be eaten. Humans have a tolerance for some level of some poisons... Many nuts have trace levels of cyanide, but people eat them anyway.... Beans if not soaked can make people very sick, etc ...
The core problem is lots of people eat things that aren't ideal - especially when starving.
Lots of people have gluten sensitivity, they get a inflamed gut when they eat it, but they eat it anyway.. so it's a poison, but it doesn't kill them quickly, and they will argue gluten is a food...
There are very few perfect foods with no downsides: eggs get pretty close, but even then some people have allergies
What if it "contains a neurotoxin that causes lathyrism, a neurodegenerative disease, if eaten as a primary protein source for a prolonged period."?
https://en.wikipedia.org/wiki/Lathyrus_sativus
If the problem manifests after years of consumption blame it on user error and not eating a balanced diet.
But why bother at all in this case? Funsies?
With Lathyrus it's stated pretty clearly in the wiki article; it produces seeds when other plants do not, thus it's still eaten especially when there's no other crops. This has lead it to stay in cultivation and become part of some cuisines, which people still make because of tradition
Profit or philosophy but mostly good old fashioned stubbornness
