Why Does Pineapple Hurt Your Mouth?

Some people know this experience: you have some pineapple for a snack and find dealing with the pain of a sore mouth afterward. But why?

This must be a coincidence, right?
Actually, it’s normal for pineapple to make your mouth sore.

Pineapple contains an enzyme called bromelain that breaks down proteins. So, when you eat pineapple, this enzyme is breaking down the proteins in your mouth, and casing a legitimate case of a sore mouth.

Not to worry, if you’d like to enjoy pineapple but are susceptible to the bromelain, cooking the pineapple helps to deactivate the enzyme and will give you a pain-free eating experience!
