[00:00:00]Why does your mouth burn when you eat fresh pineapple? You probably think you're allergic, but the truth is way weirder. Pineapple contains an enzyme called bromelene. Its only job is breaking down proteins. And since your tongue and cheeks are made of protein, when you eat pineapple, it actually starts breaking down the surface of your mouth. The enzyme disrupts your mouth's protective layer, exposing sensitive nerves. Combine that with the fruit's natural acidity, and that's why it burns. But don't panic. The second you swallow, your stomach acid quickly deactivates the enzyme and your mouth repairs itself in just a few hours. It's not allergy, it's biology.
