Why does pineapple make your tongue tingle?
Show answer & explanation
Answer: Enzyme digests mouth proteins
Sugar crystals scratch mouth — Wrong. The tingling is from bromelain enzyme digesting proteins in your mouth, not sugar crystals.
Vitamin C irritates skin — Wrong. Vitamin C adds acidity, but bromelain enzyme is the main cause.
Enzyme digests mouth proteins ✓ — Correct! Pineapple contains bromelain enzyme that breaks down proteins in your tongue, literally digesting your mouth! Cooking destroys it, so canned pineapple doesn't tingle.
