Pasta.
Curcubits.

Pancakes
Pumpkins
Muskmelons
Caramel

Ice cream

Mangoes
Cilantro
Milk Chocolate (love dark)

I can enjoy it sometimes depending on how it is dressed.  But I cannot account for my taste.  Nothing to do with medical problems.

pumpkin
melon (all kinds - except watermelon)
AVOCADO!!!
sausage

I need to add corn to that list. I absolutely hate corn. Growing up I refused to eat "corn on the cob" so my family thought I was weird.

Bacon, though I don't eat meat any more any way, but I always thought this was just burnt fat useful only for making grease for eggs to be fried in.

Gravy-how do people eat that crap? Brown is more disgusting, but white gravy makes me puke faster, rather immediately. I remember I used to hate Kentucky Fried Chicken baskets before about 1985, because they refused to let you have mashed potatoes without gravy, and I couldn't eat that shit. 
I once was promised a hot breakfast at a motel in Florence Ky, and it was biscuits covered with gravy, devised by some sadistic control freak who wouldn't let people choose. Now I know a lot of people like gravy, or claim they do (there's no way they're not just masochists), but certainly over a third of the population is like me and can't stand gravy, and the maniacs who cover stuff in gravy for other people, they know this. They're just being hateful.

Pepsi products. I really thank them for this, because if a restaurant has only Pepsi garbage, it's easier for me to just order water and lemon. I can drink the Pepsi product of root beer and pepsi cola, and the defunct 7-up, but that's it.

Bratwurst-I don't know if most people can like this, but I'm seeing about half, and they have to be masochists.

Pickles or relish mixed in with tuna fish-gag a maggot junk there. It just doesn't mix. Epic failure, but lots of people claim to like it

White Castle-if you haven't had these, a warning. Those people claiming White Castle is good and cheap, they're lying on both counts. They order dozens of those little disgusting things, and I've actually just gone out and picked up grass outside my place to eat when I was given White Castles and didn't have money to get anything else.

Those new fangled milk shakes, or so called milk shakes, all the fast food places have. They aren't edible or drinkable. Disgusting. Whoever came up with this idea was a "hater" of the first degree.

Meat Loaf. I always thought everyone hated this, and no doubt most people do, but a loud minority rave about this putrid junk. My mother used to punish us when we were bad by making this stuff. I really couldn't eat it without being two days hungry, and preferred again to just eat the grass outside.

Strawberries. Again, this is one of those things people claim to love, but prove they don't. When you're a kid in a group of kids, remember when an adult asked the group what flavor ice cream to get? There was always one kid, or maybe two, who insisted on getting strawberry, so we'd get the 3 flavor batch, but those one or two would also insist on digging into the ice cream first, and they'd not even touch the strawberry, and often they'd make sure there was nothing but strawberry left for the chocolate lovers. They never touched the strawberry flavor ice cream, and this happened about four times with different groups of kids.

Pepperoni-Again, most people don't "like" it, but most will put up with it. A meat that tastes like a tomato. Sour, but otherwise bland of flavor, and with the fat grams of meat. The "haters" will always insist on a group pizza being pepperoni out of sheer meanness and hatefulness. 

Most candy bars. Terrible mixes. Peanut butter does NOT mix with chocolate. Neither does shredded coconut. Neither do nuts. Too many "nut bars" claim to be candy bars. The only real candy bar is Three Musketeers.

Drystyx, by any chance, do you consider shrimp to be aliens??  Just curious.
