    I’ve got a reverse one for you then! I have a friend who’s allergic to a ton of things, and we were eating roasted pineapple at a potluck. She said, ‘I love pineapple even though I’m allergic to it! The burning isn’t too bad.’ And I was all like, ‘it does that to everyone; those are the digestive enzymes in the pineapple.’ She was amazed that she’d found a fruit she wasn’t allergic to lol.

        Pineapple hits with a one-two punch. Raphides, sharp microscopic crystals of calcium oxilate, scratch the mouth, causing micro-abrasions, while Bromelain breaks down the proteins of the mucus lining the cheeks and tongue. Together they allow the acid of the pineapple to more effectively attack the mouth, giving that traditional stinging sensation.
