We weren't allowed to 'not like things' when I was growing up. My mum had lived thru' the Blitz & rationing and she had a carbon-steel intolerance of food faddery or - worse! - waste. You ate what you were given, and you were grateful. Period. Consequently I grew up pretty much bereft of 'dislikes', so never had to 'acquire' any tastes. I like good food better than bad food, but there's pretty much nothing I won't eat - and enjoy, on some level.
You are who you are. Your upbringing is a factor, of course, but that fact that you have broad tastes almost certainly would have been true however you were raised. I say this because I had a similar upbringing, but my one food hate is actually the result of a "carbon-steel intolerance of food waste" and my brother's story is the opposite of yours.
As a kid, I got a lot of chest infections, so took a lot of antibiotics, mostly in liquid form with some child friendly flavouring added. The banana was the worst, but I could just about gag down a teaspoon of it four times a day, as directed. One summer day my father bought for us a treat -
choc wedges! (an ice cream). But instead of getting the standard vanilla we expected, he bought banana flavoured. It tasted just like the penicillin. But my father, born during the depression, could also not tolerate waste so he made me eat the whole thing. Since that day I have not been able to go near bananas. The smell makes me retch. I rather clean up vomit, than overripe mashed bananas. I was once baby sitting a toddler, and had to leave the banana she smeared in her hair because I didn't think I could clean it up without throwing up.
My brother, brought up under the same regime, was a picky eater then so would sit for hours after the end of a meal, staring at a tablespoon of now ice cold vegetables. He still is a picky eater, hardly eats any vegetables, only white bread and his favourite - only - pizza is just tomato, cheese and ham.
Oh, and did you really have beer, coffee, sushi, olives, cigarettes, cous cous, red wine, blue cheese, whisky, curry, and green tea (thanks everyone for that list!) growing up? My acquired tastes are mostly things I did not have as a child.
