Fish with a strong fishy smell.

The fish itself has a fishy smell, so we must pay special attention to the price of the fish, some people may choose cheap fish, but we can find that these cheap fish have relatively strong taste, and this kind of fish should not be bought.

This kind of fish may live in a polluted water environment for a long time, which may contain heavy metals or formaldehyde. Eating this kind of fish can easily make the body sick.

Giant deep sea fish.

Many people in life may prefer to eat deep-sea fish, thinking that the nutritional value of fish living in the deep sea will be higher.

The environment of deep-sea fish is more complex than that of freshwater fish, and there will be more heavy metals in it. Deep sea fish is not recommended for children as it can cause serious damage to health and even the nervous system.

salted fish

Xianyu is a kind of pickled food that many people prefer, especially in Sichuan or Chongqing and other places, they especially like to eat salted fish.

Studies have found that salted fish contains dimethyl amino acid salt, which is prone to produce carcinogens and dimethyl nitrite after entering the human body. Salted fish is a pickled food. Large amounts of salt need to be added during the production process. Eating too much can easily increase blood pressure and even damage kidney function, especially in patients with urinary system inflammation or high blood pressure.

Freshly butchered fish.

I believe that when people buy fish, they like to buy fresh and lively fish. They think that such fish are tender and delicious after slaughtering.

Here, we need to remind you not to eat freshly slaughtered fish immediately, because this fish contains a lot of heavy metals. Excessive intake can easily lead to food poisoning, and it is easy to make the content of heavy metals in the body too high and affect its own metabolism. After slaughter, the fish cannot be eaten for a short period of time. Try to brew with water for 1-2 hours before eating.

fish in sludge.

There are many fish living in the sludge, among which loach and eel are representative. Fish living in sludge basically contain heavy metals and formaldehyde, and have more parasites.

In the production process, everyone chooses the way of high temperature cooking. Many parasites have a habit of being resistant to high temperatures. Even if they can eliminate most parasites, they can't kill them all. Long-term consumption of this fish can cause great harm to health.

Fish that have been frozen for too long.

In order to prolong the shelf life of fish, many people will store the fish in the freezer to prolong the shelf life of the fish and avoid the deterioration of the fish.

If you keep fish in the freezer for an extended period of time, not only will it lose nutrients significantly, but the fish eyeballs in storage are also particularly cloudy, indicating that the fish is not fresh and will not benefit the body even if eaten.
