At Pomergranates and Paper they ask you to list a few things each week.
Here are foods that freak me out:
1 mushrooms--yucky texture
2 mussells, clams, oysters--yucky texture
3 olives--yucky texture
4 liver-yucky texture and taste
5 cooked cabbage-if you can't get it past your nose, you shouldn't eat it
6 brussel sprouts--same as above
7 raw tomatos-yucky texture, but great if cooked in something!
8 sushi-raw meat...eewww
