Seafood can be eaten during menstruation. Women’s menstruation is controlled by the hypothalamus-pituitary-ovarian axis, which is directly affected by sex hormones and produced directly by the endometrium, so it can be said that menstruation is very self-control, as long as there are no sex hormones in the diet, which basically won’t affect menstruation. Seafood is a common food, rich in protein and calcium, high nutritional value, and there is no scientific evidence to prove that seafood contains sex hormones, as well as blood or hemostatic ingredients, so eating seafood during menstruation will not affect menstruation, as long as there is no allergy to seafood, can be consumed normally. In the menstrual period due to the reduction of sex hormone levels, the pelvic cavity, as well as reproductive organs, part of the intestinal tract are congested, so some women will have diarrhea during menstruation. If you are prone to diarrhea after eating seafood, it is recommended that you consume less or no seafood during menstruation to avoid aggravating the burden on the stomach and intestines, resulting in aggravation of diarrhea.
