Raisins are used by women during menstruation to prevent hypoglycemia and to replenish blood and qi. Because raisins, which are obtained by drying fresh grapes, are relatively rich in sugar, and most of them are fructose, the presence of a lot of bleeding during menstruation can easily cause low blood sugar, so it can improve the symptoms of low blood sugar. At the same time, raisins are rich in iron, vitamins and amino acids, and women during menstruation are prone to anemia. Therefore, eating raisins in moderation during menstruation can be very helpful in improving the symptoms of anemia, pallor and cold hands and feet.
