Why Pineapple Stings Your Mouth and How to Stop It
If you’ve ever eaten fresh pineapple and felt a sharp tingling or burning sensation on your tongue or lips, you’re not alone. That uncomfortable feeling isn’t an allergy for most people — it’s a natural chemical reaction caused by compounds inside the fruit.
What Causes the Stinging Sensation?
Pineapple contains an enzyme called bromelain, which helps break down proteins. While that makes pineapple useful for digestion and meat tenderising, it can also irritate the delicate tissues in your mouth.
The fruit is also acidic, and when acidity combines with bromelain’s protein-digesting ability, it can create a prickly or burning sensation on the tongue, gums, and inner cheeks.
Why Some People Feel It More
Sensitivity varies from person to person. You may notice stronger stinging if:
- Your mouth has small cuts or sores
- You eat large amounts quickly
- The pineapple is very fresh and raw
- You already have sensitive oral tissues
Is It Harmful?
For most people, the sensation is harmless and fades within minutes. However, if you experience swelling, hives, or breathing trouble, that could indicate an allergy and medical attention should be sought immediately.
How to Reduce the Sting
Simple Tricks That Help
- Cook or grill it: Heat breaks down bromelain.
- Soak in salt water: A brief soak can neutralise enzymes.
- Pair with dairy: Yogurt or milk coats tissues and eases irritation.
- Rinse your mouth: Water or milk can calm the burning.
- Eat slowly: Smaller bites reduce exposure.
Fresh vs Canned Pineapple
Canned pineapple usually doesn’t sting as much because it is heat-treated during processing, which deactivates much of the bromelain enzyme.
Enjoy Pineapple Without the Pain
Pineapple is packed with vitamin C, antioxidants, and hydration benefits. With a few easy adjustments, you can enjoy its sweet-tart flavour without the uncomfortable after-effects.
