The top 10 things I HATE eating/finding in food in no particular order:
Raisins
Celery
Caraway seeds (Irish bread is he[ck] it has that AND raisins)
generic Frosted Flakes (it's dreadful and it tastes like wallpaper paste)
canned Hash
frozen ravioli (it has NO flavor)
black licorice (unless I'm somehow in the mood to eat it, then I find it disgusting again when I do)
tofu (though I can tolerate it in soup...but not by much...it's a texture thing)
grapefruit (only had it once, never again)
anything that hurts my stomach really bad.
