It is possible to eat red dates during menstruation, which contain iron, which can play a blood tonic effect, and also eat black fungus, animal liver, cinnamon and other foods during menstruation, which can also play a blood tonic effect. During menstruation, you should avoid cold, spicy and irritating foods that may affect the menstrual flow and cause abdominal pain. Some women are prone to edema during menstruation, causing a slight increase in weight during menstruation, but often the weight will return to normal after menstruation as urine increases and sodium is excreted. These women should pay attention to a low-salt, low-fat diet during their menstrual period, and if necessary, they can eat more diuretic foods such as winter melon, which can help their bodies recover.
