Name a food that you just can't eat because the thought of eating it makes you sick?

Cooked spinach makes me gag just thinking about it. Or any kind of cooked greens for that matter.

Also, mushrooms
calamari (how could anybody eat ANYTHING with suction cups?)
any organ meat
turnips
eel
deer, veal

Eel
Squid that is not deep fried to within an inch of its life and then I will only eat the cheerio parts, not the leggy parts.
Swiss Cheese (the only cheese I don't like)
Hate cooked fish, love sushi - go figure

And - I'm weird like this - I hate sweet with my meat. What I mean is, fruit cooked with meat (raisins, apples, orange marmalade glaze, whatever), anything kind of sweet sauce served with meat - gross. Like pineapple with ham - that kind of thing.

An old lady friend of my Grandmother once made tunafish with apples and grapes in it and I would NOT eat it and my GM made us sit there til I finished it. Blech!
