As a tropical and subtropical fruit, pineapple is not only rich in nutrition, but also has many neglected health functions. When you are full, eating pineapple can help digestion and relieve constipation.

Pineapple is rich in sugar, fat, protein, vitamins, calcium, phosphorus, iron, carotene, nicotinic acid, ascorbic acid and so on. It helps digestion, mainly because it contains bromelain. This enzyme can decompose protein in the stomach, supplement the deficiency of human digestive enzymes, and restore the normal digestive function of patients with dyspepsia. In addition, bromelain also has a certain therapeutic effect on nephritis, hypertension and bronchitis.

But in real life, people often have allergic reactions because of eating pineapples. In order to avoid allergy, pineapple can be soaked in salt water for 10 minute before eating, which destroys the allergenic structure of bromelain.
