Taboos for pregnant women to eat fish
Although fish is rich in nutritional value, it is not suitable for pregnant women. Mercury content makes pregnant women taboo to eat fish. Because mercury content may affect the growth and development of fetal brain. When mercury enters pregnant women, it will destroy the central nervous system of the fetus in uterus, resulting in low cognitive ability of the fetus. Sharks, mackerel, swordfish and square fish all contain mercury. Therefore, it must be pointed out that pregnant women had better not eat these fish, which is safe. In addition, pregnant women contaminated by fish should not eat fish. Fish farmers who grow rice in paddy fields or ponds near paddy fields should apply a certain amount of pesticides or insecticides. These harmful substances pollute the water in the field, then seep into the fish and accumulate. Studies have shown that fish have strong accumulation ability and high tolerance to pesticides and insecticides. Insecticides accumulated in live fish may lead to human poisoning, especially in the fetus. Among them, fish head is the most dangerous, and pregnant women should avoid eating it. There is also a more poisonous fish, which is polluted by industrial waste gas, waste water and waste residue from factories and mines, especially chemical plants. These fish contain heavy metals, such as cadmium, lead and mercury. Pregnant women may not have much problem eating by themselves, but the fetus is very sensitive and fragile.
