Some thoughts:
I grew up in a meat and potatoes family. Learning to eat vegetarian meals was a long process.
I grew up in Georgia and it's a long ways from Hawaii. All I knew of pineapple was canned pineapple. For probably the first thirty years of my life, I had a terrible opinion of pineapple.
Then I lived on the West Coast, a lot closer to Hawaii, where fresh pineapple was readily available most of the year at not crazy prices. I finally tried fresh pineapple that hadn't been rotting in transit for weeks and weeks and absolutely loved it.
Fruits and vegetables need to be fresh. There is an art to selecting them. People with a meat-centric diet seem to often not really know how to cook them well.
Overcooked veggies lose a lot of their flavor and nutritional value. Undercooked vegetables can be hard to digest or have other issues.
I have a mild tomato allergy. I can eat pizza and ketchup. I react poorly to raw tomatoes.
It's not obvious I'm allergic because I need to keep eating tomatoes regularly over several days before I get hives. But I do need to limit tomatoes and the more processed, the better.
Growing conditions, harvesting methods, storage conditions and on and on can impact taste for fruits and vegetables.
