For me, I think the main reason would either be texture or that the item is gross. I've had foods that didn't taste good, but I usually mark that up to it being poorly made, made with bad ingredients or just a recipe/version of that food that I didn't like.

I love, love, LOVE cheese. I'm also pretty sure that I will not eat maggot cheese. (never say never, but it's damn unlikely). I also don't have much interest in eating brains, eye balls, testicles, etc....

I will eat chicken or calves liver. I also eat sushi including the raw stuff.

THe main thing that I can think of that would fit the "texture" thing is fat, like from pork or beef or if the ends of bacon aren't cooked. I've had tongue that had a great flavor, but the texture bugged me.
