Bananas and anything banana-flavored (even just that smell makes me sick)
Liver (and probably any other internal organs, for that matter)
Onions
Marmite/vegemite
Sweet potatoes
Deer
Duck
Turkey on a bone (turkey cutlets are fine, turkey cold-cuts are fine)
Fish without shells and/or without feet (i.e. I'll eat lobster, shrimp, oysters, squid, octopus)
Malted milk balls
Sponge cake from a bakery (homemade is ok)
But I love snails -- go figure
