Hypothetically speaking, if somebody was only allowed to eat 1 type of food for the rest of their life and only drink water, what could they eat and not die?
Dishes like soup and stuff don't count, it has to be only 1 thing, like only chicken or only cucumber and stuff like that. My best guess would probably be some kind of plant, because I know there's stuff in those that we cannot produce but need, meanwhile all the stuff in animal meat is probably naturally producible. I really don't know much about biology tho, so really curious to see different answers.
I also wasn't fully sure which category this belongs to... It feels spiritually general discussions, but I figured it's TECHNICALLY about nutrition, so... yeah
