It is possible to eat oysters during menstruation. Oysters are rich in protein, vitamins and minerals, and are a nutritious food. During menstruation, the body is in a state of high elasticity, and the demand for protein, especially high-quality protein, is relatively high. The moderate use of raw oysters can effectively replenish the vitamins needed by the body, which have the effect of enhancing resistance. Raw oysters contain various minerals, especially high iron content, which can relieve recent anemia. Oysters are relatively nutritious, but they are a cold food and are not recommended to be consumed in excess during menstruation to avoid inducing or aggravating dysmenorrhea. When consuming oysters during menstruation, it is recommended to be light and avoid making them spicy and stimulating in taste to avoid affecting normal menstruation.
