bananas.
I'm never eating one. Just the smell turns me off.
Everything banana-flavored is disgusting.
If someone puts even the tiniest piece of it in foods or drinks, I guarantee you I will detect it right away.
Spicy stuff. I got tired of hurting myself when eating should be pleasurable. Also, raw stuff. I don't get why so many people like raw oysters. How do they not get sick? Raw, bitter veggies suck for the most part too.
