I've never liked tomatoes since I was a kid & although I'll eat stuff that has tomato sauce (like bolognaise and lasagne) I have a phobia of tomato soup. I can't stand to be in the same room as an open can of it, I want to be sick if I can smell it cooking, if I see someone eating it I flinch! I can genuinely say I'm scared of tomato soup. Am I normal?!

And if it genuinely makes you feel ill to smell it, I wouldn't call it a fear but rather a disliking of something that makes you sick, for whatever reason it does. Fear makes it sound irrational.
but, i'd have to say, NO
No, it's not normal to be scared of food.
