Can pregnant women eat dragon fish?

Freshwater fish is widely considered to be a healthy food, and some fish also contain heart-protective fat. However, different types of fish accumulate different amounts of mercury, a natural element that is harmful to the human body. However, not all freshwater fish are suitable for people to eat. Among them, there are more taboos for pregnant women. For example, can pregnant women eat dragon fish?

Pregnant women can eat dragon fish in moderation, but they should be careful when eating the following types of freshwater fish:

The first type: Fish from the waters around chemical companies cannot be eaten.

We all know that the waste gas, waste materials and sewage from chemical companies are continuously discharged into the surrounding seas. The toxic substances in these wastes will then penetrate into the bodies of freshwater fish, causing the excessive content of heavy metals such as cadmium, lead and mercury in fish to increase, which will cause great harm to the sensitive baby in the belly, and the baby may be poisoned.

Second: Freshwater fish that show signs of corruption should not be eaten

This is because when freshwater fish becomes corrupt, it will produce a large amount of histamine, which will cause a strong reaction, which is very bad for the health of pregnant women and fetuses.

The third type: freshwater fish with high mercury content should not be eaten

Studies have found that the mercury content in the bodies of king mackerel, great white shark, swordfish and tilefish is very high. Mercury is very harmful to the human body. Therefore, expectant mothers must not eat these four types of fish during pregnancy, because eating these fish may affect the brain development of the fetus, and it is also very easy to cause the birth of a deformed fetus.

The fourth type: Fish raised in rice fields or ponds and weirs close to rice fields cannot be eaten

Farmers will inevitably use a certain amount of fertilizers or pesticides when planting rice seedlings. We all know that these compounds will pollute the field water, and gradually seep into the fish body through the field water and accumulate. Studies have shown that freshwater fish have a very strong ability to accumulate fertilizers and pesticides, and their tolerance is also very high. If a pregnant mother eats this kind of fish, the toxic effects of the fish can easily enter the fetus's body and cause fetal poisoning.
