Fish in general. As a kid I absolutely disliked the strong taste and oily texture.

I'm very open with my foods and like to retry everything I disliked in the past, things I still don't like are Olives (weird metallic taste I don't like), Tomatoes (slimy texture at normal size, cherry tomats are fine), unaltered boiled egg yolks (so dry, so so dry), Oatmeal (texture issue), and a couple others I can't think of at the moment. I enjoy most of the texture based ones as soon as the texture is altered.

Bananas and potatoes. I can't say that I enjoy bananas now, but I tolerate them kinda and eat them regularly.

We ate potatoes for just about every meal when I was a kid so I started to dislike it, but now I love potatoes in every form and eat it as much as I can.

Sauerkraut was just too overwhelming as a kid, but I love it now. Some other foods were the same, but that is the one I remember.

I liked black olives as a kid, then hated them in my teen years through early 30s and find them tolerable now.

A lot of people hated vegetables as a kid if they were made bland by boiling, and like them a lot more when they have them roasted or just with some seasoning. I remember having bland steamed brussel sprouts at home which are just awful but one of my friends roasted them and they were awesome. My dad cooked up some awesome seasoned steaks and that friends parent bought the wrong cut and cooked it well done so it opened my eyes to how much of a difference preparation makes.

Pig and chicken feet. Fat is so good.

I fucking love Cauliflower, I thought I didn't like it because I grew up poor and didn't really get fancy veggies

i used to hate peanut butter. idk why

Gumbo. My mom made it a few times and I always hated it. Turns out she wasn’t making it correctly until I had my extended family make it the way our family did from Louisiana and now I can’t get enough of the stuff.

My family goes all out on gumbo, making a pot that will cost around $400 (pre-pandemic pricing, not sure how much it went up since) but have every little thing everyone wants from shrimp and sausage to chicken and all the little fixings in it.

I hated sea food as a kid, and still mostly do, but now I can stand shrimps and mussels.

And vegetables too, like a lot of people (apart from pumpkins and stuff like that, those are still nightmare for me)

Swiss cheese

Wine

Have always had a pretty broad palate but swiss cheese I couldn't like until I was older, and could taste its flavor relationship to good Parmesan, the nuttiness.

Wine I made a conscious effort this year, that wasn't a maturity thing, it was a project but have found several I actively enjoy rather than just barely tolerate.

Oh, and turnips - I didn't like them, then I enjoyed them raw with dips, now I do like them raw or cooked.

Most fish. I always liked salmon, but didn't like most other fish; now I like all fish I'm aware of.

Beets, hated em growing up, absolutely love em these days

Pickles. They were too strong and sour for me. Now I love 'em.

Tomatoes. Especially raw ones!

No, if anything it's the opposite, there are foods (mostly junk foods and beverages) I used to love as a kid but now I find revolting. Most other veg and controversial foods like olives or blue cheese were always on my yes list though.

I do have some things i didn't like that now I tolerate, but saying that I love them or like them is a stretch. I think coffee is one, I drink some and can even get addicted to it but I don't consider myself a lover. Another example is eggplant, I used to hate it as a kid and now I tolerate it without loving it.

Brussel Sprouts with black pepper 🤤👌

Blue cheese
Brussel sprouts
Cauliflower soup
Green peas
Brocoli
Olives

Kale. I hated it as a kid, but that's because my parents never removed the stems, and then boiled it down into mush, neither of which is the correct way to cook kale. Now that I cook my own, I love it and eat it regularly.
