American cheese, because I threw up once as a kid after I ate some. Honestly no big loss, I wouldn’t eat American cheese now even if I’d never thrown it up because it’s a trash cheese.

Also, any meat where I can tell what it once was. I don’t want to eat anything off of a bone, or anything’s skin, or god forbid a fish is served whole. Growing up we used to have whitefish sometimes on the weekend and no fucking thank you.

Car sickness while eating a blueberry nutrigrain bar and now I can’t eat anything with cooked blueberries. I used to love eating blueberry muffins.

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.

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.

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.

I had the flu one time and barfed up shredded hashbrowns. Let me tell you, that stuff gets all stuck in the crevices of your mouth and teeth when you vomit it. Couldn’t eat hashbrowns for a good year after.

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.

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.

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.

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

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

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.

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.

Ruins food ? an event ? like what event ? I’d be quite mad any food were ruined for me

Hm, reading the comments I understand better. Fortunately I can’t say I have experienced anything traumatizing enough to keep me off any food

Plain water. One time when I was young, I got thirsty and drank a lot of water straight from the tap. Then got sick and threw it all up. Now I have a hard time drinking plain water. I can drink water with flavor, I can drink water with food.
