bones in fish. even if it is a very small one, i cannot go on eating the fish, although i absolutely LOVE fish.
lamb. it smells and tastes like old, wet and peed on wool. yeah, yeah, people keep telling me that if it tastes and smells like that it was not LAMB, but sheep. it makes no difference. it tastes and smells horrible and i will not eat it.
fuzzy fruit skins. like peach and kiwi. just thinking about the sensation i get in my teeth when biting into them makes me cringe.
there are more, but those are the biggest food stops i have.
