Foodstuff? I’m going to go with Yes. *audience members start pulling their dictionaries from their backpacks, briefcases, handbags and messenger bags, and the muttering begins immediately* Smok(e)y bacon crisps? No. Exist in 1800? Yes.
Vegetable = fruit? Yes. Not eaten by humans? Were I to be annoyingly and misleadingly literal, I’d say Yes. The AOTC is not normally eaten by humans. But the reasonable answer is: No, because the vegetable (and animal) component is consumed by humans.
