Is pineapple suitable for individuals with allergic constitutions?
Generally, individuals with allergic constitutions can consume small amounts of pineapple if they are not allergic to it. However, those who are allergic to pineapple or have a highly sensitive constitution should avoid it. If in doubt, it is advisable to consult a medical professional in advance. Detailed analysis is as follows:

If individuals with allergic constitutions have previously consumed pineapple without experiencing any discomfort, eating a small quantity of pineapple soaked in salt water may reduce the irritation of pineapple's bromelain enzyme on the mouth and provide additional vitamins. In such cases, consumption typically does not trigger allergic reactions.
If individuals with allergic constitutions have had prior allergic reactions to pineapple, symptoms such as rashes or difficulty breathing may occur after consumption. Even without a confirmed pineapple allergy, individuals with highly sensitive constitutions may still experience adverse reactions due to their heightened sensitivity. In such cases, pineapple consumption is not recommended.
Before consuming pineapple, individuals with allergic constitutions can try a small amount first. If no abnormal reaction occurs, they may then consume an appropriate quantity. If discomfort arises, they should stop eating immediately and monitor their symptoms. If symptoms are severe, prompt medical attention should be sought to avoid health complications due to allergic reactions.
