With the popularization of nutritional knowledge, fish meat has become the best choice for many "meat eaters" because of its unique nutritional advantages.
However, although the fish is good, it does not mean that it is the perfect food, and like other foods, you can't eat fish carelessly.
Which types of fish are best not to eat?
1. Uncooked fish
When cooking fish, make sure the fish is fully cooked, eating uncooked fish can cause parasitic infections.
Also, do not put undercooked fish and other food plates together to avoid cross-contamination.
2. Over-fried fish
Although the fried fish tastes more attractive, it will oxidize the fat of the fish after frying at high temperatures, producing harmful substances such as free radicals and benzopyrene.
Secondly, fish proteins, vitamins, minerals, etc. will be destroyed at high temperatures, which will seriously affect the absorption of nutrients.
3: Marinated salted fish
In the salting process, nitrite can react with the protein decomposition products of the preserved products to form nitrosamines, which are a strong carcinogen.
4. Fish with high mercury content
In general, large and long-lived fish have higher mercury content, such as longevity fish, sailfish, bigeye tuna, marlin, mackerel, shark, and horsehead.
This fish is not recommended for pregnant women, women with a conception plan, lactating women and children.
Which types of fish are best not to buy?
Many people do not know how to choose fish, go to the market to buy fish is also what the fishmongers give what they want, as everyone knows, sometimes the fish they buy is rough and fresh, and even some "soaked potions".
A owner of a kaikai fish shop revealed that when selecting fish, the first thing to do is to reject "these kinds of fish", and these fish and aquatic products owners never give to their families to eat.
First, fish that are too big or too small
No matter what kind of fish you buy, don't buy too big or too small, it is best to buy "seven or eight points large" fish, too small fish has not yet matured, the flesh is not tender enough, and there will be more thorns;
Fish that are too big are rough and taste bad. For example, crucian carp to buy between 7-8 two, carp, sea bass is best to buy a pound of three or four two, grass carp to buy about 4 pounds of taste is the best.
Second, the fish eyes are gray and opaque
Fresh fish eyes are clear, translucent, full and convex, and there is no obstruction on the surface of the fish eyes. If you find that the fish eye is gray and opaque, or there is blood in the fish eye or the fish eye is inverted, it means that the fish is not fresh.
Third, the color of the water in the water tank is not correct
There are many large and small tanks in the fish shop, and all kinds of fish live in it, if there are many algae impurities in the tank or the water in the tank is dark green, it means that the water has not been changed or cleaned for a long time, which will affect the health of the fish.
4. Frozen fish fillets
In addition to a variety of fresh fish, there are also some frozen fish fillets on the market, such as Longli fish fillet, basa fish fillet, there are many traders who take the basa fish fillet to impersonate the dragon fish for sale, the nutritional value of the two is much worse, the earthy smell of the basa fish is very heavy, and some have to go through the "soaking potion" treatment to fishy and preserve. Therefore, when encountering frozen fish fillets, be sure to buy them carefully.

3. Patients with bleeding diseases
Fish fats contain eicosapentaenoic acid (EPA), which has the effect of preventing cholesterol from adhering to the walls of blood vessels, which is very beneficial for atherosclerosis.
However, excessive ingestion of EPA will inhibit platelet agglutination, easily aggravate the bleeding symptoms of patients with bleeding diseases, and is not conducive to disease recovery.
4. People who take certain drugs
Chlorpheniramine, diphenhydramine, etc. are histamine receptor antagonists, while histidine-rich foods such as fish and shrimp can be converted into histamine in the body.

This part of the fish is more poisonous than arsenic
This part is the fish bile.
As we all know, fish bile is a traditional Chinese medicine, in the ancient mainland a book "Criterion for Evidence" once recorded that it has the effect of clearing heat, detoxification, blind pain.
Therefore, many people listen to the so-called folk remedies and treat themselves by swallowing fish bile, but what everyone does not know is that most of the ancient physicians used fish bile as external medicine, rather than direct internal administration!
In February 2019, a woman in Kaifeng, Henan Province, mistakenly believed in home remedies, swallowed 4 fish gall in a row, resulting in her vomiting and diarrhea, her face turned pale, and finally diagnosed patients with acute kidney failure and acute liver failure.
Therefore, many so-called folk remedies and earthworks are not reliable, whether it is traditional Chinese medicine or Western medicine, it must be taken under the guidance of a doctor.
Then if you really eat the fish bile by mistake, if the patient is awake, he can induce vomiting if he is allowed to induce vomiting.
If it is not allowed, it is still recommended to go to the hospital for treatment as soon as possible, especially if some patients have finished vomiting, they must go to the hospital as soon as possible.
