The most popular edible marine fish species are listed below, along with their names.

 

Why fish can be harmful

Well, or useless. Everything seems to be known about this product: proteins, vitamins, unsaturated acids, iodine. But with the last hitch. After all, it collapses instantly, which means that the fish brought from distant seas is not so rich in it. In river fish from the nearest river, it may be more. But this is if the river is clean.

The problem of almost all fish today is the pollution of the oceans and seas with rivers. Fish, of course, are not mushrooms, but they also accumulate harmful substances. Especially mercury, more precisely, methylmercury, which negatively affects the nervous system and not only. Well, do not forget that fish is one of the most allergenic foods.

Dangerous fish to eat

8. Escolar

Often sold as whitefin tuna because it resembles tuna in both appearance and lifestyle. Its meat is very tasty, however, eating too much of this fish can cause keriorrhea, a form of diarrhea.

Escolar contains a non-digestible fatty substance called gempilotoxin, which gives the meat that juicy, buttery flavor and texture. However, this substance can cause intestinal problems if you eat too much of this fish. Keep this in mind and eat it rarely and in small portions.

9. Bluefin tuna

Most types of tuna, including yellow, black, albacore, bigeye, contain mercury in varying amounts. Bluefin tuna has the highest levels of mercury and the lowest environmental ratings.

Longline fishing is the most common method of catching tuna. It involves the use of baited hooks attached to a hooked fishing gear - a bottom line. In addition, due to the high demand for bluefin tuna, it is overfished.

Bluefin tuna grows to an average of 230 kg, but puberty is very slow. They are often caught before they have time to give birth.

10. Red Snapper

This fish is on this list because of the ongoing problem of overfishing. This has led to the fact that since the 1980s the population has been constantly declining.

You should be careful when buying a red snapper, because similar tilapias are often sold under his name. The best alternative to snapper is black cod and striped bass.

11. Caviar of paddlefish, shovelnose and sturgeon

Black caviar is obtained from sturgeons, whose stocks are now severely depleted. These prehistoric giants have lived for many billions of years, but due to the high demand for their caviar, sturgeons are dying out.

Paddlefish and sturgeon are long-lived, slow-growing fish that are only able to reproduce late in life, which greatly increases the likelihood of overfishing.

What kind of fish is better not to eat at all

The most harmful fish are predatory, large and adult. Here is a list of types of fish that should not be eaten too often.

Acne

In our country, it is considered a simple fish, and the Japanese highly appreciate it and often add it to sushi rolls. Eel is really tasty, but it is prone to contamination with polychlorinated bivinyl and the already mentioned mercury. These substances have a negative effect on both the nervous system and the liver. You can replace eel with squid, for example, Pacific or Atlantic.

Atlantic flounder

Pretty tasty fish, but it lives in very polluted areas of the Atlantic coast. Other rather dangerous types of fish are also found here:

• Big rhombus;
• Turbot;
• Halibut;
• Gloss;
• Dab.

You can replace them with Pacific halibut.

salmon atlantic

In fact, its fishing is prohibited. That is why it is grown on farms, in limited spaces. It is there, in crowded conditions, that infection occurs: salmon transmit various diseases and parasites to each other. For treatment, pesticides and antibiotics are used, which makes the fish even more harmful. Sometimes the salmon escapes and infects fish living in the wild.

Shark

One of the leaders in mercury content. This metal is a provocateur of neurological disorders in children. A shark should not be eaten at all, not only by babies, but also by expectant mothers, as well as nursing ones. The body does not remove mercury for a whole year. This fish can be replaced with halibut.

Atlantic bluefin tuna

Another leader in the accumulation of mercury among fish. Only yellowfin, longfin and skipjack tuna can be called safe species. In canned form, you can even use it daily.

Tilapia

Recently, it was considered a harmless fish. But recent studies, for example, from the wake forest medical school, have shown that this fish does not have so many useful fatty acids, but no less harmful ones than lard. If you eat tilapia regularly, there is a risk of high cholesterol levels and the development of asthma, heart disease and arthritis. In addition, tilapia is a very allergenic fish.

Oily fish

This is not to say that it is too harmful, but the waxy substance gempylotokisin gives it an oily taste. It is not too harmful, but can provoke disorders in the digestive tract. In order to neutralize its effect, it is recommended to bake oily fish on the grill, or just fry.

kafelnik

One of the record holders for the accumulation of mercury. In addition, during the catch of this fish, sanitary rules are often not observed, which leads to frequent poisoning.

sea ​​bass

It cannot be said that it is too harmful, but under its species, cafes and canteens may offer other, less useful types of fish. In addition, he also accumulates mercury actively.

catfish

We are talking about overseas catfish, which is grown in captivity. Usually it is a very large fish, but in Asian countries, hormones that are not the most useful for our body are used to grow it.

Mackerel

The Atlantic is quite safe, but other species are very rich in all the same mercury. So, pay attention to where the mackerel came from.

Pangasius

Not only the inhabitants of the seas can be hazardous to health. The river inhabitant pangsaius lives in the dirtiest river in the world - the Mekong. Untreated water from chemical plants and tanneries, fertilizer residues, and water from sewage are drained here. It is frozen in the same water. And in order for the fish to grow big, it is fed with hormones.

Shrimps

Not only fish can be harmful to health. Imported shrimp contain a sea of ​​antibiotics and chemicals, often transported along with rat hair, insects and droppings, and E. coli. Safe seafood can be called squid and mussels.

The healthiest fish for humans

About the fact that fish is useful, we are told from childhood.

This product is truly unique.

See for yourself, I will briefly list the main advantages of fish, how useful fish is:

• Fish contains ESSENTIAL fatty acids

I think that many people know that our body needs a constant supply of two essential polyunsaturated fatty acids - these are alpha-linolenic acid (OMEGA 3) and linoleic acid (OMEGA 6).

These acids are not synthesized by our body, so we must get them from food.

For more information about the benefits of these acids and what products they contain, I told here.

But, there are also two more OMEGA 3 fatty acids that are also vital for our body:

• eicosapentoenoic acid (EPA)
• docosahexaenoic acid (DHA).

These acids are not interchangeable, they are very necessary for our body and are found mainly in fish!

This is one of the main factors indicating why eating fish is so beneficial.

The amount of OMEGA 6 to OMEGA 3 in our body should be approximately equal!

But, in fact, in practice, we consume much more OMEGA 6 due to the fact that they are more common in foods than OMEGA 3.

This creates an unhealthy imbalance in the body, which manifests itself in a variety of diseases (arthritis, depression, baldness, atherosclerosis, dementia, etc.)

Therefore, according to many reputable scientists, we should eat foods that increase the proportion of OMEGA 3 and reduce the proportion of OMEGA 6. And fish contains the most OMEGA 3 !!!

Based on this, the World Health Organization (WHO) recommends that you eat two to three fish dishes a week.

• Fish is a source of complete protein, which is quite easily digested in our body.
• And fish is the richest source of vitamins and microelements, it is vitamin A, D, potassium, phosphorus, iodine, sulfur, which our body needs.

Salmon has the most optimal balance of OMEGA 3 to OMEGA 6.

The amount of EPA and DHA in this fish is perfect!

The daily dose of Omega-3 fatty acids is 85 milligrams.

This dose is found in just 100.0 salmon!

Varieties of raw fish dishes

Despite the risks, dishes made from raw fish are gaining more and more popularity every year. The most common are:

1. Sushi. Raw fish and rice are used as the basis for rolls and other dishes; secondary components can be anything from sesame to cucumbers.
2. Sashimi. It is a finely chopped raw fish fillet, served with wasabi and soy sauce.
3. Poke salad. It is made from pieces of fish with vegetables and spices.
4. Ceviche. Consists of lightly marinated fish and lemon or lime juice.
5. Carpaccio. A dish of thinly sliced ​​raw fish or meat seasoned with a sauce containing mayonnaise.

Thermally unprocessed fish is the main ingredient in many dishes common in different countries.

red tuna

Redfin tuna contains high amounts of mercury. She enters his body with food. The same thing happens with other marine fish that tuna feed on. Such a food chain ensures that mercury also enters our body (after eating tuna).

Farm-raised salmon

Very often farmed salmon is kept in small and cramped tanks. The sanitary conditions of these places do not meet the standards. They are filled with bacteria and parasites, so the salmon becomes infected. In addition, fish nutrition is not given due attention. It is obvious that in such conditions it is unlikely that it will be possible to grow a healthy product.

Pangasius

If you do not want to risk your health, then it is better to completely refuse this fish. In recent years, it has been quite common on store shelves. Unfortunately, behind her attractive appearance, there are many unpleasant surprises that we don’t even know about.

Pangasius is bred at the mouth of the Mekong River. It is one of the most polluted in the world. It is known that dead fish, the remains of bones and a certain type of flour, the quality of which leaves much to be desired, are used to feed pangasius.

dangers

Fish can be a source of helminths and some bacterial agents, which can lead to infection. It may also contain harmful chemicals.

In the pulp of fresh fish, the most common are:

1. Flatworms. Widely distributed in the tropics of Asia, Africa, Southern and Eastern Europe. When it enters the human body, it causes opisthorchiasis - a severe lesion of the liver and gallbladder, which can even be complicated by cancer. According to experts, the cause of infection is not only the consumption of raw seafood, but also unwashed hands and kitchen utensils after them.
2. Tape worms. They can be found in both river and sea fish, most often found in salmon species. It causes diphyllobothriasis, which scientists estimate can affect up to 20 million people each year. The disease is manifested by dyspeptic disorders (constipation or diarrhea, vomiting, heaviness in the stomach), asthenovegetative syndrome (weakness, fatigue) and signs of vitamin B12 deficiency (anemia, funicular myelosis).
3. Roundworms. Cause anisakiasis. This type of worm can only be present in marine fish. Helminths do not live long in the human body and quickly die without causing significant inconvenience. However, in rare cases, they can trigger a strong immune response that ranges from discomfort and abdominal pain to severe anaphylaxis.
4. bacteria. It has been established that bacteria of the following genera may be present in fish: Listeria, Vibrio, Clostridium, Salmonella. In healthy people, these microorganisms do not cause disease. However, in people with a weakened immune system (the elderly, children, patients with HIV infection), they can lead to severe complications.
5. chemicals and heavy metals. Special attention deserves the concentration of harmful substances. Raw fish is a source of mercury, polychlorinated biphenyls, polybrominated diphenyl ethers, etc. The main reason for the presence of such side components in seafood is water pollution and the use of poor quality feed. During thermal exposure, the concentration of these substances decreases.

Eating fish without heat treatment is associated with a number of health risks due to the content of parasites, bacteria and harmful substances.
