Suggestion: eat fresh and digestible food during menstruation, not cold and indigestible food. Because eating cold food during menstruation will hinder digestion, and secondly, it will easily damage the yang of the human body, leading to poor menstrual blood, resulting in too little menstrual blood, even dysmenorrhea and amenorrhea. During menstruation, you should also eat more laxative foods, such as fresh vegetables, fruits, peanuts and walnuts.
