Pregnancy hunger does not eat, usually has an impact on the fetus. Pregnant women in a state of hunger are prone to insufficient nutrient intake by the body, prone to hypoglycemia, thus unable to provide sufficient nutrition for the growth and development of the fetus, which can seriously affect the safety of the fetus. Poor nutrition during pregnancy is not only associated with fetal abnormalities, gestational anemia, gestational diabetes and postpartum hemorrhage, but also adversely affects the growth and metabolism of the fetus after birth. Therefore, it is important for pregnant women to consume a nutritionally balanced diet consisting of diverse foods to improve maternal and child outcomes. In early pregnancy, the diet should be light and easy to digest, with fewer and more frequent meals to ensure the amount of food eaten, and more folic acid-rich foods to reduce the occurrence of fetal malformations. In the middle and later stages of pregnancy, the diet of high quality protein such as fish, poultry, eggs and lean meat can be increased appropriately, which is beneficial for fetal retinal development. Appropriate increase in milk intake, milk is rich in protein and is also a good source of calcium. Eat iron-rich foods, such as animal offal or red meat, to prevent the occurrence of iron deficiency anemia.
