I always got apple juice when I was ill as a kid, and I was ill a lot. As a result I cant stand apple juice or cider, they taste like sick

My parents took me to an Italian restaurant when I was a child, and the smell of olive oil was so overpowering I couldn’t get in. Still have trouble with olive oil to this day, maybe 15 years later

Orange soda.

With my third baby, she did not want to come out (in stark contrast to her sisters, who all seemed to want to give me about one hour of advance notice before getting born) and the midwife said, before trying induction, try castor oil, sometimes it will kick the labor on. Not a spoonful, no. A whole bunch. And don’t puke it out. I chased it with orange soda because I liked it but figured I could certainly manage without it.

Oh God. I couldn’t even look at orange soda without nausea for several years. And it didn’t even work, I still had to get induced!

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.
