Aunt that is menstruation, menstruation can be appropriate to eat pineapple, but should not be eaten in large quantities. Pineapple is rich in sugar, vitamin A, vitamin B1, vitamin C, niacin, iron and many other trace elements. For women who are menstruating, there is no information and research indicating that pineapple should not be consumed, so women who consume pineapple appropriately during menstruation generally will not affect their health and do not need to worry too much. However, as pineapple contains pineapple protease, glycosides, etc., which can have an irritating effect on the digestive tract, it should not be consumed in large quantities, so as not to cause vomiting, diarrhea and other uncomfortable symptoms. In addition, those who are allergic to pineapple should not consume pineapple to avoid causing related allergies. During menstruation, women are advised to consume room temperature pineapple and should not consume refrigerated pineapple. During menstruation, the overall dietary principles of women should be based on high protein, high vitamin foods, and a reasonable combination of diets, so as not to cause discomfort during menstruation.
