There is a traditional saying in traditional Chinese medicine, that is, "replenishing the internal organs with the internal organs", that is, eating pig liver can nourish the liver, the liver opens the eyes, and eating liver can nourish the eyes; eating pig pancreas has a negative effect on the pancreas. Benefits, can cure diabetes. For this reason, people have a special liking for eating animal offal. However, the British health department has officially issued a warning not long ago: Pregnant women should eat less, preferably not pig liver and other animal livers, to reduce the risk of congenital defects in the fetus. It is well known that pork liver has high nutritional value. It contains 20% protein, multiple vitamins, calcium, phosphorus, iron, zinc, etc., all of which are essential nutrients for the human body. In addition, eating pig liver also has the therapeutic and health-care functions of enriching blood, protecting liver, nourishing the skin and preventing and treating night blindness. Pork liver can be said to be an economical and affordable food. However, the latest research results at home and abroad show that it is better for pregnant women to eat less pork liver. It has been proposed many years ago that pregnant women should not eat animal liver. At that time, it was clinically discovered that some babies had congenital defects, but the cause was unknown. People have done a lot of research on this, and for the first time they learned about the relationship between vitamin A and fetal malformations. Research continues, and some studies have found that more than 20,000 children who consumed large amounts of vitamin A during pregnancy were born with cleft lip, cleft palate, ear, eye and urinary tract defects, and a few suffered from central nervous system or thymus hypoplasia. After conducting a close follow-up survey of women, they analyzed the data and pointed out that during pregnancy, especially in the first three months, if a woman's daily intake of vitamin A exceeds 15,000 international units, the risk of fetal teratogenesis increases. Where does this vitamin A come from? Food and medicines made from animal livers. Pregnant women usually need 3,000 to 5,000 international units of vitamin A every day. The same amount of vitamin A in the livers of cattle, sheep, chickens, ducks and other animals is higher than that of pig livers, and chicken livers are several times that of pig livers. I don’t know if I don’t tell you this, but I was shocked when I heard it. In order to protect the health and safety of the next generation, the UK has reminded pregnant women to eat less animal liver and its products.

So how can we ensure that pregnant women need vitamin A during pregnancy? You can eat more foods such as fresh fruits and vegetables that are rich in beta-carotene, because carotene can be converted into vitamin A in the human body. At the same time, you can also obtain folic acid from the B vitamins necessary for pregnant women, which can help prevent congenital anencephaly in the fetus. It can be said to kill two birds with one stone.
