That's an interesting example. My impression is that most Americans consider raw potatoes to be unpalatable, but not poisonous. It's rare to eat them, but mostly because of taste rather than health consequences. Other countries seem more likely view them as actually harmful. I was surprised in Russia to realize that potato peels were always removed, with the Russians I spoke to being alarmed that Americans didn't worry about eating them. Are you possibly Russian, or at least close enough to incorporate similar cultural views?
This article (https://www.healthline.com/nutrition/raw-potatoes) is "fringe" for suggesting that one might eat raw potatoes, but I think summarizes the scientific viewpoint: "Raw potatoes are more likely to cause digestive issues and may contain more antinutrients and harmful compounds. Yet, they’re higher in vitamin C and resistant starch, which may provide powerful health benefits. In truth, both raw and cooked potatoes can be enjoyed in moderation as part of a healthy diet."
Anyway, while not the same as the Amanita Muscaria case, I wonder if there is something close to parallel happening with potatoes, with one culture feeling a particular preparation is necessary for safety, and another thinking it is just a culinary desire.
