Well, IIRC there were stages to trying new things, kinda like:
Test 1: rub plant on forearm, see if it has a reaction.
Test 2: eat small piece of plant/thing to see reaction
Test 3: eat progressively larger pieces and rinse and repeat
They’d also dilute them in water and drink progressively less dilute solutions. Also, as other people mentioned, notice what other bugs and animals are eating.

This is probably only in survival situations

Smart smart, it’s crazy how much you can figure out when you know what to look for
