My list:

Organ meats, I do like liverwurst, but that is so much fat I rarely eat it anyhow.
Bologna, used to be a favorite, fried, but the fat again. and it is just too CHEAP What's in it?
Cooked zuchini- once had some that was bitter-I now avoid it.
Cilantro-tastes like soap.
Blood sausage. A favorite as a kid for breakfast,my family called it by the Polish name Keishka, then I asked what it was in English now I think of it as Blood sausage and get nausous just thinking about it.
Blue cheese dressing. Tastes and looks like vomit.
Macaroni salad -store bought- something tastes bitter, I must be peculiar.
Cherry Pie- its slimy.
Whipped cream- sometimes makes me feel like my throat is closing up and I'll be choking. It's not the taste or texture, because I feel that way even after I eat itI. But not always, so It must be some additive. Fake whipped topping, the ingredients are too gross!

I used to dislike any kind of crucifer, broccoli, brussel sprouts, cabbage (except in cabbage rolls, etc.)

Now I love cabbage, avoided Brussel spouts until last year I tried fresh instead of frozen, and they weren't bitter. After being married to someone who hated almost everything, it was a releif to be able to eat again. I probably would still be avoiding weird vegetables if I hadn't suffered all that gastromic deprivation.

As a kid I couldn't eat hardboiled eggs, the dryness of the yolk made me choke. Mom wouldn't let me color eggs, nor eat only the white. Finallly learned to choke down those yolks as an adult. I think of all the cholesterol and fat I could avoid now that I know it is healthier NOT to eat the yolks, but feel to guilty to toss them!

Also, I LOVE custard. My favorite dessert. (Never ate it as a kid)

I have difficulty experimenting with strange animal products, sometimes I will sometimes I won't. I think it makes me thinkabout the death of the animal. Animal products I'm used to don't bother me anymore. ( I kow I "ought" to become vegetarian, because I don't think I could slaughter animals personally, so it is dishonest to eat them. Except killing fish doesn't bother me, even though I like keeping pet fish. But eating octopus does bother me. I ordered some by accident in an Asian restaurant, described as seafood soup.
It was dead already, so I figured I might as well eat it, but it saddened me. They are very clever animals.
Jellyfish was interesting. An Asian freind raved about it. It didn't have any flavor of its own that I could detect, and it was prepared in a cold salad. It had a texture somewhat like calimari but crunchier.

Trying new vegetables and fruits I always find interesting. I may not like them, but there is no "squeamish" factor here.

Hated seaweed, flavor was too strong, and repeated on me. Until I ate sushi several times.
