well, my religion has some food restriction and regulation, so there are lot of food I can't eat: pig, dog, blood, snake, amphibian, animal with claw, eww animal, etc.
And there are some things that I just won't eat, like still living organism (you know, eating those mini-octopuses alive is just so wrong. One of Korea delicacies, if my memory served me right. Also heard of those dishes where they quick-fry fish-body so the fish still live). No raw meat/egg/milk. Cook it first please!
I also avoid any young-animal meat (veal etc).
And those sea-cucumber is yuck (forgot the name). And whole eel, sliced eel meat is ok.
I hate chilli! When I eat one of those, my tongue lose most of it tasting ability which in turn, make me unable to enjoy my food. Almost all my family is chilli lover, I really believe their tasting ability is rather weak so they need capsaicin (the chemical on chilli which cause the hot sensation) to boost their tasting ability. Or they just masochistic and enjoy the pain. Or just addicted to endorphins. Whatever, I don't like chilli.
I won't eat meat from head (like, fish head; chicken head, etc) and chicken feet (the part with fingers). It just ewww...
