ketchup. as a kid, i was fine but now... ugh. plastic bottles, the sound they make, the amount of sugar. bleurgh.
Kim Chi - there is something about it I can't stand. It should have stayed buried. The same with Lutefisk
Green peppers and sour cream.
I try sour cream every few years trying to develop a taste for it but no luck yet.
Melons (the actual fruit, you perverts). Not sure why, but I just don't find them appetizing. I've eaten them when no other fruit was available but avoid otherwise.
Raw banana actually makes me feel ill. Something about the consistency more than the taste, I think, since I like banana cake, fried banana, and so on.
Brussels sprouts, sauerkraut, most fast food, especially McDonalds.
Okra, green bell peppers, cucumbers, kimchi, head cheese, oysters, clams, chowder, anything from Taco Bell or Burger King.
Ketchup, the smell alone makes me gag.
Onions. They are simply disgusting and make your breath smell like a cemetery.
Any vegetable that is slimy. That goes for stewed tomatoes, boiled okra or anything like that. Which is funny because I like oysters on the half shell and escargo!
Sugar----I mean it. I don't know how I ate all that sugar as a kid! A second is curry.
Raw tomatoes, avocado and okra! God, even thinking about them makes me gag
Let me see. I detest okra, brussels sprouts, Taco Bell, and peanut butter & jelly sandwiches (just gagged a little).
Fish, any fish.
Coconut.
*honorable mention: cilantro, it gives me migraines*
Milk(technically a beverage), olives and salmon.
