Tinned cream of mushroom soup. Used to love it as a cheap way to make a mushroom pasta or whatever when I was at uni and on a student budget. One day the texture just did not play right with me and now I often physically gag when I think about it.

Went to a party once and ate a bunch of nacho cheese doritos among other things. Ended up getting sick from some undercooked cookies and I could taste the doritos when I threw up. Now I get queasy just thinking about them

Had slightly poisonous mushrooms, vomited for three days.

Needed two years to be able to eat mushrooms, again.

The body remembers.

My mom was cooking some beef and brown sauce dish as I was reading a book with cannibalism at way too young an age. I associated that smell with eating human flesh for over a decade and would have to leave the house as it was cooking.

gin, and because of flu, ham for a long time. fortunately i can eat ham again.

Sweet potato fries. Or overly orange fries for any reason (sometimes the frying just seems to make them orange, especially curly fries?).

Was youngish, friend took me out to lunch and I had a meatball sub with sweet potato fries. Yum yum. Until, of course, 3am the next morning when all that came up and was orange and potato-y. I refuse to try them again to this day. Although I love sweet potatoes, lol, just not sp fries.

I used to love Chilli con carne, but not anymore. One day I woke up not feeling well and we were having Chilli con carne for lunch. Despite my condition, I sat down at the table and started eating. It didn’t last long. In a few minutes, I was feeling queasy and had to dash to the bathroom to throw up. Ever since then I can’t look at, smell or eat a Chilli con carne dish without remembering that day.

This doesn’t fit the question at all, but I like to eat chicken and stars when I’m sick. They mostly taste like chicken flavored salt and taste exactly the same on the way back up.

Three bean salad, or anything with sweet vinegar sauce. That combo of vinegar taste and sickly sweetness is the single most disgusting thing I’ve tried. I can stomach most of the foods I dislike, but three bean salad will literally make me gag if I try to put it in my mouth.

lemon baked goods make me legitimately naseous (how tf u spell it???)

Canned chicken. One time I decided to buy a can just to see if I can take a break from eating canned tuna (would have two cans of tuna as a meal)… the moment I opened the canned chicken I was like nooooooope. It smelled fkin gross.

You know how to can get turned off of eggs if you get the egg ick.

I don’t think I do know actually. But here’s an attempt at answering this question anyway:

And bonus, anybody know why that happens?

We are usually very quick at relating sickness or even discomfort to the food we ate at the time or slightly before. This is a very valuable trait to avoid food that is unhealthy or even poisonous. But it’s only based on correlation, so it can turn us off food that is not actually causing the sickness but we just happened to eat at the time.

Cream soda. I had a plastic dinosaur shaped cup to drink from one summer and was required to keep it the entire time. I drank a 2 liter of cream soda over a couple days then every single other thing I drank from it tasted like cream soda. Water, milk, other soda. For a whole summer. I don’t drink cream soda now. Weirdly enough, my brother, another dinosaur cup haver from that summer, loves cream soda.

Mushrooms.

Everything about them disgusts me, from the way they look, to the way they smell, the texture they have and the disgusting mouldy, dirty taste. Even seeing them growing in the ground grosses me out and I’ll take a wide path around them to avoid going near them.

Outside of magic mushrooms, they have literally zero redeeming qualities. I hate them with a passion and it’s basically the only food I never grew out of hating.

Gin, I think.

It’s debatable about whether this counts for the question, but I’m commenting because this wasn’t a case of “drank too much, was very sick” kind of story, which many people have about alcohol. Basically I was at a small party and I downed a shot of clear liquid that I believed to be vodka. It was not.

I didn’t even know there was any gin in the house, I hadn’t seen anyone drinking it. I wasn’t keen on the taste of gin before, but the unexpectedness of the taste was so bad I was sick. People were concerned because they worried I was overly-drunk, but it was entirely the flavour that did it. Now, anything that tastes or smells remotely similar to gin makes me feel sick.

Though even if we are counting gin as a food here, this is very much gin not being consumed in its normal way - I have never met anyone who would choose to do a shot of neat gin.
