Although pineapple has many functions, its harm can't be ignored.
1, "5- hydroxytryptamine" in pineapple is a neurotransmitter containing ammonia, which has a strong effect on contracting blood vessels and smooth muscles and raising blood pressure, and the result is headache. Every100g of fruit juice contains 2.5 mg ~ 3.5 mg.
2. Pineapple contains a variety of "biological glycosides", which are irritating to human skin and oral mucosa. Therefore, the mouth feels itchy after eating untreated raw pineapple.
3. Pineapple contains bromelain, a protein hydrolase. After extraction, it has a strong function of decomposing fibrin and blood clots, and it is a medical drug. A small amount of bromelain in pineapple is decomposed and destroyed by gastric juice after being eaten in the stomach. However, a few people have allergic reactions to this enzyme, and most of them are "quick-onset" allergic reactions. After eating15 ~ 60 minutes, abdominal pain, nausea, vomiting, urticaria (commonly known as rash), headache, dizziness and other symptoms appear. In severe cases, dyspnea and shock may occur.
Healthy eating:
1, If you want to keep the fresh taste of pineapple, you can soak the sliced or block pineapple in salt water (generally the salinity of cooking) for about 30 minutes, and then soak it with cold boiled water to remove the salty taste, which can also achieve the desensitization effect.
2, pineapple peeled and diced, cut into pieces or pieces, boiled in boiling water before eating. Bromelain began to denature at 45℃ ~ 50℃, and more than 90% of it was destroyed at 100℃. Glycosides can also be destroyed and eliminated at the same time; Serotonin is dissolved in water. The taste is also improved after boiling.
3, the baby who eats for the first time only eats a piece of biscuit size. If there is no abnormality, the amount can be increased appropriately next time.
4, do not eat too much pineapple every time, excessive consumption is harmful to the stomach.

You must do a safety test before eating pineapple, because some people are naturally allergic to pineapple, and once they use it, they will have diarrhea and vomiting. Similarly, because the efficacy of pineapple is very powerful, people with blood coagulation disorders, preparation for surgery, metabolic dysfunction, skin ulcers and other problems had better not use pineapple.
