Is everyone a little allergic to pineapple?
There’s a scientific reason why fresh pineapple burns your tongue, and no, the answer is not (always) allergies. Many people feel a tingling, sometimes-burning sensation when they bite into fresh pineapple, and lots of them—incorrectly—chalk up the feeling to the fruit’s acid content.
Intense itching and hives are often the first symptoms of an allergic reaction. Hives may show up on one or more places on your body. You may also have digestive symptoms, including stomach pain, vomiting, and diarrhea.
