Interesting pineapple

Do you know the peel of the pineapple contains ingredients that can cause inflammation in the mouth.

So you shouldn't use the same knife to slice the pineapple after you've peeled it.

Be careful with fresh pineapple.
Some people are hypersensitive or allergic for pineapple and this results in aching gums as one of the first symptoms.
The allergy will develop further and may cause a dangerous situation.

When you cook pineapple the enzymes that cause an allergic reaction are destroyed. That's why allergic people often (but not always) are able to eat preheated pineapple.
