In the cold winter, pregnant mothers will catch a cold if they are not careful, and low immunity is a common phenomenon. So, how to improve the immunity of pregnant mothers? I recommend several methods for you. Strengthen nutrition for pregnant women – 3 macronutrients have immune-regulating functions. Pregnant mothers can improve their immunity through diet. Sufficient protein, appropriate amounts of vitamins and some trace elements all have immunomodulatory effects. Protein is the material basis for the defense function of the immune system of pregnant mothers. In late pregnancy, the mother and fetus reserve about 1,000 grams of protein, of which 500 grams are needed for the growth of the placenta and fetus, and the other 500 grams are used for the mother\’s uterus and mammary glands.
