I'm very well known in my family for being an insanely picky eater. I can't stand tomatoes, tuna, mayonnaise, mustard, cooked peas, spinach, asparagus, peppers, anything even slightly spicy, lunch meat, sloppy joe, onions, pears, roast beef, pork, egg yolk (no matter the preparation), cream cheese, relish, baked potatoes (if wrapped in foil only, microwaved doesn't bother me), soups, pizza that's too greasy or watery, and some other things. I tolerate few forms of leftovers. But generally I've noticed things that are chewy, acidic or spicy are what bother me most. Mixtures of thigs having too many flavors are also irritating, so my food has to be kept separate.
Although tomatoes are on the ew-list, anything made from tomatoes (ketchup, sauces, ect.) I love. I don't get that. lol
