Same meal in Japan: A particularly nasty batch of natto, and sea urchin (sushi). Yuck-o.
As a kid, when it wasn’t so much “forced myself to eat” as “was forced by my parents to eat”: blood sausage. It looked wrong, smelled wrong, tasted wrong, it was just simply wrong. And to make matters worse, the other dish available for that meal was kidneys. The blood sausage actually made them look appetizing, but they still weren’t that great.
Now: Shio-kara. It’s a type of pickled squid in some really repulsive day-glo purple sauce. At least, that’s how the pub I was in was preparing it. Normally when I drink, the alcohol numbs me to point of being able to eat some truly foul things quite happily, but I had one bite of this and gagged, forced myself to eat another bite to be polite and almost hurled, then tried to maneuver the plate over toward some other inebriate who’d appreciate it more.
My mother was a good cook, but the one thing I hated her to make was her homemade vegetable soup. I vaguely remember meat bones, some vegetables, and the broth tasted like dishwater with tomato flavorings. My father loved it, and she made enough for a couple of meals. I found the stuff inedible and wondered what he thought of it. Of course, he also ate my mother’s cole slaw which had enough vinegar in it to start a car engine.
My parents (who were usually good parents) were real assholes when it came to dinner(because they were both depression era kids who ate anything their insane parents fed them), and I was to eat everything on my plate. I remember getting yelled out for asking if there was anything else to eat. Fortunately, she only made that shit in the winter.
When i was in high school or early college, we visited my father’s sister in Iowa. She made a chef’s salad with boiled egg crumbled all over the thing. I ate the vegetables and left the egg behind, when my mother told me to “clean my plate”. This was one time I really wanted to hit my mother in the mouth. Boiled eggs is one of the nastiest things on God’s green earth.

Uni (sea urchin) for me. Words have yet to be invented (or the Japanese one hasn’t been translated yet) that adequately describe how nasty that stuff is.
Most other Sushi is the Food of the Ogs though.
Have to agree about calimari. When done badly, its pretty gross, but when you get it right, its delicious.
I went to Southern France last year, and a group of us went to a sea food resterant. We ordered a seafood platter. I’ve eaten a lot of seafood, including some very disgusting things (whole baby squid and octopus were probably the worst).
But even I was surprised by what we got. It was all raw, and some of it was still alive. It looked like they had scooped the whole thing out of a rockpool. It had Oysters (like licking phlegm of a tortoise), Clams, cockels and mussles and a few other bits that I couldn’t identify.
We were particularly disgusted when one of the clams started moving. Turns out it had a baby crab inside it.
We still ate it all though.
Chitlins and turnip greens - why would anyone eat something that smells that bad?
Pickled beets
Uni - sushi should not be slimy
but the worst…
We love Korean food, especially the little dishes of kim chee (pickled cabbage and hot chile paste) and what-not that come at the beginning of the meal. New restauant and they put the little dishes of various chile paste covered goodies in front of us. I pick up a small 2x1 inch piece from a dish and pop it in my mouth. It’s raw beef that is covered in chile paste and bean curd. The taste was hidous and the texture worse. I swallowed it whole just so I wouldn’t have to look at it again. I gagged and told Hubby what it was and he had to try it too. Yep raw beef. He spit his bite out back onto the plate. Ewww.
comes wrapped up in individual slices. From Krapt foods. Or even worse, cheese whiz.
Now liver is my favourite and whatever that bad smell is about durian I’ve never noticed it. Tastes like vanilla ice cream with a hint of strawberry. Smell the same too.
I am sorry, but I have to disagree here. I am disgusted by kim chee, especially after I learned how it is made.
I swallowed a tablespoon of Liquid Smoke once as part of a gross-food-eating contest. Everything I ate for the next week tasted like it had been stored in a smokehouse. God, it was ass-nasty.
I’ve eaten a lot of things in my life - good, weird stuff. Nothing really grosses me out - from tripe, to kidney, to tongue, brains n’ squid…
But there is one thing that will make me gag just thinking about it.
My grandmother’s Vol-au-vents. Good LORD. It’s like schoolroom glue with teeny weeny bites of chicken in it, peas and carrots… celery I think… I dunno, it’s a goopy mess and it’s BEYOND gross. Served on crappy puff pastry shells.
Every family gathering where we serve stuff “buffet style”, she makes a pot of 'em.
My father and I turn all shades of green just thinking about it. Where’s a pukey smiley when you need one?
Venison.
The worst part is that I’ve tried it 4 times in my life.
Everyone who hunts tells you that “you just didn’t have it done right, try it my way.” and it still tastes like raw sewage.
My ex-wife’s ministrone soup disaster. She used a slow cooker and put the macaroni in it and let it sit all day. It was starch soup.
“Cheese-a-roony”. Some kind of zucchini/cheese mixture.
Also, mushrooms. (You know which ones.)
Let it be known that I love seafood. Calamari: steak, fried, sushi, yum. Fish all over the place. Shark. Crabs and lobsters. Clams, mussels, scallops. Most of them.
But I hate caviar. It’s salty, slimy, nasty stuff that I think people only convince themselves to eat because it’s so damn expensive. “It’s an acquired taste, and I’m not rich enough to eat it a lot, but I know that it’ll start tasting good eventually if I can get more.”
Raw oysters. Yick.
And the worst - small blue crabs. For what it’s worth, they were batter-fried, though they were whole. Let me repeat: you’re supposed to eat the entire damn thing, shell and all. I pick one up, look at it, and cram it into my mouth. The experience is like biting into a wet paper bag of crabmeat mixed with fingernail clippings (which isn’t that surprising, chitin being chitin). It came right back out, and back into the bay from which I suspect it came - the restarant had a patio.
Chinese dried mushrooms. They have to be soaked for a day, and the smell is gag-worthy. 
I will gladly eat most of the foods mentioned in this thread, although I’ve never eaten chitlings, and going by the descriptions here, I probably won’t…
Salad… yuckk…
I lived in Asia for the past three years, for 6 monthes of that in Korea.
Kimshe is wonderful if done correctly. Yes, it’s pickled cabbage in hot sauce. On paper it is supposed to be disgusting, but actually is quite good and a wonderful appetizer.
Korean food has Chinese food beat hands down.

Spinach ice cream in Yukusuka, Japan. Served out of a soft-serve machine. Gah…
tripe. YUCK!!!
Raw oysters. Absolutely the worst. I almost yacked all over the dinner table while trying to choke those suckers down. It’s like having someone else’s loogey in your mouth. Ick
I smelled chitlins cooking once and thought that anyone who could smell that cooking and then eat it was nuts. Not gonna try that one. I know some people who love it though.
My wife wants me to find her a lamb head. She want’s to do the brain and eyeball thing mentioned earlier in this thread. I told her that I’d get it for her and I’ll even cook the thing but I’m not going to eat it (I might try the brains though, we’ll see).
singular1 I haven’t tried the spinach ice cream but just north of Matsumoto City there’s a wasabi farm that sells wasabi ice cream…mmmmm wasabi, yummy. 
Sounds like something went wrong in the handling process - it should not be that bad. The best corned beef I ever had was made with venison. Other preparations of it are no were as good as beef -IMO
