I think maybe trying tomatoes in a different form would help. Or whatever you chosen food is.
Ketchup is blended up tomatoes and corn syrup. I think it is super gross. The humble tomato, however, is a wonderful food. Eat the right tomato, in the right way, for you, will (potentially) change your mind. For instance, I am particularly about my textures. I love sundried tomatoes in oil. They are bright and punchy in flavor, and they are chewy, not mushy. If you like those things, try a bruschetta salad. The right breed can matter too. I think the Roma tomato is superior for sandwiches because of its flavor and lack of wetness, so the sandwich doesn’t get sloppy. Ripeness is important, tomatoes should be firm.
I bet, if you figured out what it is about a food you despise, you could find ways that you might like it. I have a million food particularities, but a pretty diverse pallet, because I have tried those foods in different ways to eliminate what I don’t like.











But have you tried them sundried and in oil? Honest to God. They are so good that way. The flavor is better, the texture is better. Pretty sure, if your internal glibber is the same as mine, it isn’t an issue in the dry ones.
What about pizza? Or soups?
I can’t do chicken feet, either. My husband will use them in broth sometimes, and I have to pretend really, really hard I am unaware of this, or I can’t even drink the broth. But I guess that means even they have their place
Same rule about trying things. It does help to know it’s ok to quit, after trying something.
