1. Animal liver is rich in various micronutrients, such as vitamin A, vitamin D, B vitamins, zinc and iron. It was once considered as a necessary food for pregnant women. However, excessive intake of animal liver by pregnant women will also have adverse effects on the baby. Studies have found that the risk of congenital malformation is related to excessive intake of animal liver by pregnant women. Eating a lot of animal liver during pregnancy is easy to consume too much vitamin A, which will affect the development of the fetus and may even lead to fetal malformation. Therefore, it is recommended that pregnant women eat less animal liver once a week, and control it at 30 ~ 50g each time.
2. Too salty food, too salty food will not only cause diseases such as hypertension and arteriosclerosis, but also damage arterial blood vessels, affect the blood supply of brain tissue, cause ischemia and hypoxia of brain cells, and lead to memory loss and mental retardation. The demand for salt in human body is below 7 grams per day for adults and below 4 grams per day for children. In daily life, parents should give their children less salty food such as pickles, mustard tuber, bacon and bean paste.
3. Barbecue, barbecue is one of young people's favorite foods. Some people need a little beer with barbecue almost every night to fall asleep. Barbecue, even if eaten frequently, will affect their health, which is even more harmful to the health of pregnant women. Because cooked food contains carcinogens "benzopyrene" and "nitrosamine", it not only harms human health, but also may cause fetal deformation in the abdomen and affect the normal development of the fetus.
4. Cold food, as we all know, many aquatic products belong to cold food, especially seafood, such as sea crabs. But in fact, some cold foods in vegetables are not conducive to fetal development, such as mung beans and bitter gourd. There are many women who are naturally cold. If they eat cold food more often, their body chills will increase, damaging their vitality, which is very unfavorable to the normal development of the fetus. For the healthy development of the fetus, try to hold back!
5. Tobacco and alcohol are the primary factors affecting the health of pregnant women and fetuses. From the beginning of pregnancy, the doctor will guide both husband and wife to quit smoking and drinking. Because each pregnant mother's physique is different, her sensitivity to alcohol and tobacco is also different. Alcohol can make fetal brain nerve unable to develop normally, and harmful substances contained in cigarettes will not only affect the development of baby's respiratory system and nervous system.
