Just because a pregnant woman is hungry does not mean that her fetus will be hungry as well. This is because after a pregnant woman eats, the nutrients are not all absorbed by the body at once, and some of them are stored in the body to meet the needs of the fetus. During pregnancy, the fetus mainly takes in various nutrients from the mother through the placental blood circulation, so occasionally the pregnant woman is hungry does not affect the fetus, but maternal hunger can lead to hypoglycemia, and the fetus will also feel discomfort. In addition, if a pregnant woman is hungry for a long time, her dietary intake is insufficient and various nutrients are lacking, the nutrients supplied to the fetus through the placenta will be lacking, which will affect the healthy development of the fetus in the mother’s body. Therefore, it is recommended that in addition to a normal diet, pregnant women can eat some snacks when they feel hungry, such as walnuts, pine nuts, cashew nuts, peanuts, pistachios, etc. These foods are rich in unsaturated fatty acids, rich in protein, amino acids, vitamin E, minerals, etc., which are beneficial to the health of pregnant women and fetal development. The hunger at night can be appropriate to eat some milk, bread or noodles, etc., not only to relieve hunger, but also will not cause the accumulation of food.
