For women who are not allergic to eating pineapple, they can eat pineapple during breastfeeding. Pineapple is rich in nutrients and contains a lot of vitamins, phosphorus and potassium. Eating the right amount of pineapple can improve local blood circulation, dilute blood lipids, eliminate inflammation and edema, promote blood circulation, and also have the effect of aiding digestion and relieving constipation. However, pineapples contain glycosides and pineapple protease, which have a stimulating effect and can easily cause allergies in humans, while breastfeeding is a sensitive period, it is best to eat less pineapples in case of uncertainty, so that allergens do not act on the baby through the breast milk and cause allergies in the baby. If a woman is breastfeeding for the first time, she can eat some in small quantities and observe her baby after breastfeeding to prevent allergic situations from occurring. If you only soak it in salt water, be aware that the salt water does not completely inactivate the pineapple protease, which still has the potential to cause allergies. Therefore, it is recommended to soak the pineapple in boiling water or boil it for 2-3 minutes before eating it. The high temperature can inactivate the pineapple protease and glycosides, which can reduce the body’s allergic reaction to pineapple. In addition, the mother should be careful not to have it too cold when she consumes it, so as not to cause diarrhea, vomiting and other symptoms; it is also not advisable to eat more to avoid possible elevated blood pressure.
