Oh I forgot cake frosting in general. I don't like any of it. I always scrape the frosting off. I also don't care for pie, I wouldn't say I hate it just don't care for it.
As for canned spinach, I believe it is the source of my spinach hate for many of my years. My mom loved the stuff but the smell made me gag. I couldn't go near any cooked spinach for many, many years then in my 20s, I started to eat raw spinach then started lightly cooking spinach and now I love it but it was a long road from hate to love.
You can't out-exercise poor eating habits.
