Is eating pineapple harmful? Why is it spicy when you eat it? What's the use of killing people with salt water

Pineapple is rich in nutrition and contains a lot of fructose, glucose, vitamins B, C, phosphorus, citric acid and protease. As long as it is eaten in moderation, it is beneficial and harmless to the body.

Eating untreated pineapple feels pungent, because pineapple contains a substance called "pineapple protein" and also contains irritating glycosides. Pineapple prion will decompose protein in the body, and glycoside will stimulate the tender epidermis of oral mucosa and lips. If you don't soak the pineapple in salt water before eating, you will feel paralyzed and tingling.

So before eating pineapple, clean the skin and thorns, cut the pulp into pieces, soak it in light salt water, leach out glycosides, and then eat it. After pineapple is soaked in salt water, it can also effectively destroy the internal allergic structure of "pineapple protein".
