It's fairly well known that it was hard to get europeans to really take to the potato when they first came across it
Here's my theory of why that was
It wasn't because the europeans were afraid of new foods, it was because they thought "oh, a new plant, wait, it's in the NIGHTSHADE family?! The same family of plants that has one just called DEADLY?! And you want us to EAT IT?!?!? FUCK. THAT. SHIT."
