For me this is "why I don't eat more healthy food" in a nutshell. Food that's supposed to be good for me, like every single vegetable and most fruits, really don't taste good to me at all. I've forced myself to try salad multiple times and it never tastes good to me, not even with different dressings (if anything some of them made salad taste worse). I also don't like the taste of bananas… anymore. You see I used to like bananas when I was in pre-school, I loved eating a cut up banana as a snack, but once I turned age 6 suddenly the taste of bananas became "blech!" inducing. I even tried a banana for the first time in years recently and it tastes EXACTLY as I remember it, but I still can't stand the taste. Only fruits I know I actually like are apples and grapes, and while I like orange flavored stuff like orange juice and such I don't like oranges by themselves.
I also kinda want to like red wine because people say it's one alcoholic beverage with health benefits, but red wine tastes really bland to me. I much prefer white wine because it tastes sweet.
