✅ What consuming pineapple can cause (according to established medical knowledge)
1. Mouth or tongue tingling / irritation
Pineapple contains bromelain, an enzyme that breaks down proteins. It can temporarily irritate the tongue, cheeks, or lips.
2. Acidic discomfort
Because pineapple is acidic, it can cause heartburn or worsen acid reflux in sensitive people.
3. Allergic reactions (rare)
Some people may have itching, swelling, or hives due to a cross-reaction with latex or birch pollen.
4. Digestive effects
The bromelain and fiber can sometimes improve digestion… but in excess may cause bloating or diarrhea.
5. Blood-thinning interactions (large amounts)
Bromelain has mild anticoagulant effects, so high consumption may interact with blood-thinning medications (e.g., warfarin). This is usually only relevant at supplement-level doses, not normal food amounts.
