during pregnancy, women should not eat great white sharks, mackerel, swordfish and swordfish. The water content of mercury in this fish is high, and after mercury enters the pregnant woman's body, it may have an impact on the central nervous system of the abdominal baby. In particular, it is suggested that women during pregnancy should eat fish, but try not to eat fish oil. Because fish oil will affect thrombin function, eating too much during pregnancy may increase the probability of bleeding. In addition, bottled salmon, vegetable petals, smoked fish, dried shrimps, fish gall, dead wild turtles and loach are not allowed to be eaten by pregnant women.

Pregnant women should not eat food with high mercury content, such as swordfish, square head fish and mackerel king, so as not to harm the fetal brain development and enhance the risk of abnormal fetus. Pregnant women should not eat salted fish, in case of excessive salt intake, endangering human body's water metabolism, improving kidney function, causing edema, coronary heart disease and other diseases, which is not conducive to the physical and mental health of pregnant women and their babies. Pregnant women should try to reduce the consumption of canned freshwater fish fruits to prevent excessive intake of additives, spices, melanin and other harmful substances, which will endanger the normal growth and development of the baby.

Pregnant women should really eat more fish. Fish is rich in nutrients, especially deep-sea fish, which is loved by many pregnant women because of its DNA. However, it should also be noted that sharks, mackerel king, swordfish, square head fish, etc. are not suitable for pregnant women, because excessive gong content in these fish may affect the growth and development of fetal brain.
