These four kinds of fish should be eaten as little as possible, otherwise it will be bad for your health. Let's have a look.

Most people don't know that trying not to eat these four kinds of fish will affect their health.

① catfish

Catfish in iron pot is definitely a favorite food, much like Monopterus albus, and especially likes living in the soil. Because of this, catfish contains a lot of microorganisms and parasites, so don't eat it.

From the perspective of Chinese medicine, catfish itself belongs to hair. If people are allergic, catfish is even less suitable for eating. In addition, if they have skin diseases, try to eat less catfish.

② Smoked fish

On holidays, family members like to buy some pickled food. Although this statement has been circulated since ancient times, it is especially suitable for foods that are not easy to preserve. After the curing process, the shelf life can be extended.

I suggest you eat less pickled fish, because salted fish will put edible salt and many condiments. Contact with air will produce substances such as nitrite, which is a strong carcinogen. So when you want to eat fish, you must go to the market to buy fresh fish. Don't eat pickled fish, which will seriously harm your health over time.

③ Fish in polluted areas

Fish in polluted areas are similar to deformed fish, because many factories directly discharge sewage into rivers, causing a lot of river water pollution. If fish live in this water source environment for a long time, their bodies will be affected, such as heavy metals or harmful substances.

If the polluted fish is ingested, such substances will cause harm to the body, thus affecting the health. If pregnant women eat this polluted fish, it will not only affect their health, but also cause fetal malformation, which may delay their development and seriously lead to fetal arrest.

4 heavy-flavored fish.

There are all kinds of fish, and each kind of fish will smell fishy. Fish grow in the sea over time, and it is normal to have fishy smell.

When you buy fish, the first choice is to pay attention to the price of fish. In order to catch people's gluttony, many merchants use low-priced fish instead of healthy fish. This kind of fish cannot guarantee health and quality. Low-priced fish in the market will have a strong smell, which will give off the smell of diesel oil or chemicals.

So I suggest you smell the fish before you buy it. If it tastes too strong, don't buy it. This kind of fish may grow in a polluted environment, and its body will contain a lot of formaldehyde and heavy metals, which will lead to excessive formaldehyde after intake and increase the risk of illness.

How to choose healthy fish?

1, see store equipment.

When buying fish, you'd better look at the aquarium equipment and the environment of the fish in the store, the beautification of the equipment and so on. Everything is relatively complete, because after the conditions such as filtration and temperature are good, the fish will be in good condition. If there is no equipment or the equipment is very simple, you must not buy this kind of fish, which is unhealthy.

In fact, buying fish is a relatively simple thing. I hope this knowledge can help you avoid stepping on thunder.

Step 2 look at the gills

If the end of the gill filament is rotten, there is more mucus, and sometimes the gill cover is rotten, wearing a "transparent skylight" is bacterial gill rot. If the gills are whiter than those of normal fish with a little blood red, it is gill mold. If it is caused by oral filariasis, Trichinella spiralis and other parasites, it is myxosporidia with more mucus in gills, but swollen gills, white worms or cysts on gills and swollen gills.
