Cheap doesn't mean bad. Choosing the most delicious white fish

Fish (lat. Pisces) - a group (in accordance with modern principles of cladistics - a paraphyletic group) of aquatic vertebrates. An extensive group of jawed mouths, which are characterized by gill breathing at all stages of the postembryonic development of the organism. Fish live in both salt and fresh water, from deep ocean trenches to mountain streams. Fish play an important role in most aquatic ecosystems as part of the food chain. They are of great economic importance to humans due to their consumption.

The size of modern fish varies from 7.9 mm (Paedocypris progenetica) to 20 m (whale shark).

There are (as of August 5, 2013) 32,834 species of fish known in the world. Every year, about 300-500 species new to science are described. About 3,000 species live in Russia, including more than 280 species found in fresh waters.

Origin and evolution of fish

It was believed that the most ancient jawless animals, resembling fish, are known from the early Ordovician (about 450-470 million years ago). However, in 1999, in the Chinese province of Yunnan, fossils of the fish-like creature Haikouichthys from the jawless group about 530 million years old (Early Cambrian) were found. Perhaps similar forms were the ancestors of all vertebrates.

The difference between the first fish and the jawless ones was the jaw, a derivative of one of the gill arches. In addition to jaws, fish have paired fins, an inner ear with three semicircular canals, and gill arches. Despite the appearance of the first jawed fish as early as the Ordovician, they occupied a subordinate position until the Devonian. Thus, fish and agnathans existed for more than 100 million years under the predominance of agnathans, in contrast to the present. Cartilaginous fish appeared at the turn of the Silurian and Devonian, about 420 million years ago, and reached their peak in the Carboniferous. Lobe-finned fish have lived in the world's oceans since at least the Devonian; it is possible that they already existed in the Silurian. Guiyu oneiros is the earliest known lobe-finned fish.

More than half of all living vertebrate species, namely, according to the FishBase database, about 31 thousand species, belong to fish. The number of recognized species continues to change due to the discovery of new species, as well as taxonomic revisions of individual groups. Living fish are represented by three classes: cartilaginous fish (Chondrichthyes), lobe-finned fish (Sarcopterygii) and ray-finned fish (Actinopterygii). The last two classes make up the bony fish group.

Modern cartilaginous fish are divided into two subclasses - Holocephali (whole-headed) and Elasmobranchii (plate-branched, which includes sharks and rays). Now there are 900-1000 species of cartilaginous fish.

What is the healthiest fish for humans? This question is difficult to answer unequivocally, since many fish have all the necessary saturated and unsaturated fatty acids, trace elements, minerals and vitamins. The difference lies in the fact that some representatives contain less nutrients in themselves, while others contain more. From more than 20 thousand species of inhabitants of the water expanses, we have selected the most useful types of fish for human health.

Pike

Pike discovers the ten most useful fish species for humans. This is the only non-marine representative that was able to get into our rating. According to the content of vitamins, microelements, minerals and fatty acids, pike is in no way inferior to marine life. The fish is completely absent of carbohydrates and contains easily digestible proteins. Eating pike several times a week contributes to longevity, increased intelligence and the prevention of cardiovascular disease.

Tuna

Tuna is one of the most useful fish for humans. The marine product has a whole range of useful and nutritious substances: retinol acetate (A), thiamine (B), riboflavin (B2), niacin (B3), choline (B4), B12, E, folic acid, copper, iron, potassium - this is just a small list of all the useful substances in tuna. Useful microelements and substances of this fish take part in the metabolic processes of the body, have an anti-inflammatory effect, and with regular use increase endurance, physical and mental abilities. Regular intake of tuna, like any other fish, contributes to longevity.

Herring

Herring is not only one of the cheapest types of fish, but also very useful. Atlantic Ocean Dweller is rich in DHA and EPA acids, which boost the immune system, detoxify and improve eyesight. In addition, herring contains substances that have anti-inflammatory and regenerating effects. The product is useful for hypertensive patients, as it is able to normalize blood pressure, but it should be consumed only in lightly salted form. In addition, herring is recommended for diabetics and people with high cholesterol. Fish is considered an indispensable source of easily digestible protein.

Sardine

The sardine has also been awarded the status of the healthiest fish for human health. It is a source of trace elements, minerals and contains all the necessary vitamins: PP, B2, B12, D and others. Cod has anti-inflammatory properties and is helpful in treating arthritis and other joint related conditions. Regular intake of this type of food allows you to lower cholesterol and maintain it in normal range. Sardine reduces the risk of malignant tumors, strengthens the nervous system, memory, improves metabolism. In addition, fish is considered a natural antidepressant.

Rainbow trout

Rainbow trout is very healthy for humans due to its high content of easily digestible protein and low calorie content. The animal product is replete with both fat-soluble and water-soluble vitamins. Among the trace elements present in fish, potassium, magnesium, iron, selenium, zinc, and phosphorus should be distinguished. Eating trout at least once a week reduces the risk of high cholesterol and the formation of cholesterol plaques on the vessels, and helps strengthen the nervous system and memory.

Halibut

The list of the most useful fish for humans includes halibut. The species of the flounder family is not only a source of fatty amino acids, but also a storehouse of trace elements and minerals. Potassium, phosphorus, sodium, selenium, magnesium, iron - this is just a small list of what the product is rich in. Fans of this fish who eat it regularly are less likely to have vision problems, are less susceptible to cardiovascular diseases, and do not have problems with the gastrointestinal tract. The use of halibut cod is especially beneficial for health, which is several times superior to cod liver in terms of nutritional and beneficial properties.

Cod

Cod takes fourth place in the list of the most useful fish. The inhabitant of sea waters can also boast of useful substances and trace elements, as it is almost a whole vitamin complex. There is a lot of iodine in cod, which is vital for the normal functioning of the whole organism: it increases physical endurance and mental abilities. Vitamin PP normalizes the activity of the gastrointestinal tract, making the body work like a clock, and also helps to strengthen the nervous system. Sulfur, which is part of cod, has an antibacterial effect and improves the condition of hair, skin and nails. This species is very rich in omega acids.

Notothenia

The status of the most useful fish for a person deserves notation. The nutritional properties of notothenia are in no way inferior to meat, in addition, fish protein is absorbed better by the body than meat. Like all fish, it contains essential amino acids, which are contained in it in the required amount. In notothenia, all the necessary vitamins and minerals are present in abundance. Chromium allows you to better withstand stressful situations and fatigue. People who use notothenia up to 2-3 times a week are less prone to depression and chronic fatigue. Also, this fish is recommended for people with low hemoglobin: it contains cobalt, which stimulates the production of blood cells.

Mackerel

Mackerel or mackerel is one of the healthiest fish for human health. In 100 gr. The marine product contains half of the daily norm of the protein necessary for the body, which, moreover, is also easily digested. Regular consumption of mackerel helps to normalize blood cholesterol levels. Vitamin A, which is part of the fish, is responsible for tissue regeneration, phosphorus makes the skeletal system stronger. In addition, mackerel contains sulfur, which allows the body to fight harmful bacteria. Sodium maintains the water-salt balance in the cells of the body. Nicotinic acid is responsible for strengthening the nervous system.

1 Salmon

Salmon and all fish of the salmon family are the most beneficial for humans. Salmon include such species as salmon, pink salmon, chum salmon, trout, kizhich and others. The meat of these species is not only very tasty, but also the most useful. The protein contained in the marine product is easily absorbed by the body. Salmon more than other species are enriched with saturated and unsaturated fats, omega-3 and omega-6 fatty acids. In addition, they contain such important substances for the health of each person as vitamins of groups B and D. Vitamin D is responsible for the absorption of calcium in the body, and group B is responsible for the health of the skin, hair, proper functioning of the gastrointestinal tract, and also strengthens the nervous system. Salmon must be present in the diet of the elderly and athletes. It slows down the aging process in the body, accelerates regeneration processes and is an excellent preventive product against cardiovascular diseases.

For those who honor fasting, it is very important to saturate the body with protein. What, if not a fish, will help to do this? But before using this food product, let's think about the maximum benefit of it for the body. After all, fish are different. What type of it to prefer - sea or river?

Fish are divided not only by habitat, but also by the fat content of their meat. It is also important to know where this creature was caught. After all, fish absorb into their flesh all the negative substances from an environmentally unfavorable environment. And carp, perch and crucian carp grown in artificial reservoirs are often fed with food waste, which makes their meat taste like pork. In this article we will consider the question of which fish is the most useful for humans.

Food value

The Russians have recently underestimated the inhabitants of the seas and rivers. There is more and more meat on the tables. Is it any wonder that cancer, myocardial infarction and stroke have come out on top as causes of death? Let's take a closer look at the usefulness of fish as a food product.

Its most important quality is the presence of polyunsaturated fatty acids. They are also called Omega-3s. You will not find such compounds either in animal meat, or in vegetables, or in fruits. Some varieties of fish contain more omega-3s than others. Below we will talk about the beneficial effects of polyunsaturated fatty acids on the body.

Phosphorus is another essential nutrient found in all types of fish. When there is a lack of this mineral in the body, problems with teeth, bones, and memory begin. rich in iodine. This mineral has a beneficial effect on the functioning of the brain. But the most important thing that fish is useful for is protein digestibility. Despite the fact that the meat of some varieties of the inhabitants of the seas is superior in calories to beef, these fats are quickly broken down by the body. That is why fish, as nutritionists advise, should be on the table at least three times a week.

Panacea for health?

There is no "universal pill" that cures all diseases. Therefore, there is no such product, eating which one could live a long and happy life. Fish are quite low in iron, so you should get this mineral from other sources. But the chemical composition of the inhabitants of the waters is quite rich. When looking for an answer to the question of which fish is healthier, we should focus on the problem that worries us.

Are you heartbroken? Lean on varieties of fish rich in Omega-3 (salmon, sardine, mackerel, ocean herring). This acid helps to establish a heart rhythm, reduces blood clotting, cleanses blood vessels and normalizes blood pressure.

Do you want to lose weight? Then low-fat varieties of fish (pollock, hake, navaja) will suit you. These types are high in protein.

Cod with sea bass (sea bass) will also help build muscle mass. To improve the liver, lean on halibut. To saturate the body with iodine, eat sea fish. River inhabitants (perch, crucian carp, carp, carp) will be useful for people with problems of the gastrointestinal tract. Pike meat is an antiseptic that helps fight infection. The benefits of catfish fish have long been proven. Its sweetish meat of medium fat content is good for the skin and nervous system.

Which fish is healthier - wild-caught or captive-bred?

This question is not as simple as it seems at first. On the one hand, fish in their natural habitat feed on a variety of foods. She moves in search of food over long distances, which does not allow her to accumulate unnecessary fats. Such individuals are not stressed by living in small water bodies. All this affects the taste of meat. But on the other hand, unfavorable ecology directly affects the benefits of fish for the human body.

Individuals that live in polluted lakes and rivers can do more harm than good. No less dangerous to health and some marine life. To the question "Which fish is healthier?" Asked a hundred or two hundred years ago, the answer would be: Atlantic tuna. But now its population has been catastrophically reduced. And the meat of individuals that can be caught contains dangerous mercury.

Fish living in their natural habitat are more likely to be infected with helminths than those raised in captivity. But often the inhabitants of the ponds are fed with ordinary food waste, which negatively affects the taste characteristics of their meat and reduces their beneficial properties.

by fat content

All inhabitants of salt and fresh water bodies are divided into three large groups. The main criterion for classification is the saturation of their meat with Omega-3 acids. We mentioned the benefits of this acid above. It lowers the level of triglycerides in the blood, and therefore has a beneficial effect on those who are at risk of strokes. Fish oil also strengthens nails, teeth, makes skin and hair healthy, helps fight depression and other nervous diseases.

In this light, the answer to the question of which fish is the most useful for humans is obvious. First of all, these are all types of salmon (salmon, chum salmon, pink salmon) and sturgeon (sterlet, stellate sturgeon). The fat content in them is not less than 8%. This group also includes some types of herring, eel, halibut, mackerel.

And, finally, in hake, pollock, cod, navaga, river perch, grenadier, flounder, pike, bream, blue whiting, fat is less than 4%. But in these types of fish there are a lot of proteins. The calorie content of representatives of this category is only 80-100 calories per 100 grams. product. Therefore, such fish is good for those who want to lose weight.

We disassemble the bones: what do cores and hypertensive patients need

To solve health problems, it is important to eliminate cholesterol plaques that can block blood vessels. And Omega-3 polyunsaturated acids do the best job with this.

Which category is fatty? This is mackerel. It contains many considered acids. But saturated fats, which can harm people with reduced stomach secretion, are quite few. Again, you need to consider in what form to use mackerel. It is often sold smoked. It is important to understand that such processing of meat, especially with hot smoke, reduces the use of baked or cold smoked mackerel.

A treasure trove of beauty and youth

Which fish is good for healthy hair, skin, nails and teeth? The one in which there are a lot of vitamins E and the B line. And in this regard, how not to recall the so-called red fish species. These are chum salmon, pink salmon, sockeye salmon, salmon, salmon. Their meat is very fatty, not inferior in calories to pork. But don't worry. This fat is well absorbed by the body and does not contain harmful cholesterol. On the contrary, it carries dissolved vitamins A, E and D. But most of all vitamin B, which is responsible for healthy hair shine, ideal skin condition and strong nails, is in salmon. There is so much of it that 100 grams of fish is enough to replenish the daily intake of this vitamin.

Are you afraid that, along with the density of your hair, extra pounds will stick to you due to the frequent use of fatty salmon? Then switch to freshwater fish species. Dietary, but no less beneficial for the health of the skin and hair, are perch, pike perch, carp, carp, crucian carp.

For expectant mothers

Trout is a healthy fish for pregnant women. It is less fat than salmon, but it contains no less Omega-3s. If a woman who is expecting a child eats a fish dish at least once a week, then she will more easily endure all the hardships associated with pregnancy (toxicosis, hair loss, etc.). Docosahexaenoic acid, which belongs to the Omega-3 type, lowers the level of prostaglandins, which affect the activity of the uterus and thus reduce the risk of miscarriage.

Any fish included in the diet of pregnant women contributes to the normal development of the fetus. Unsaturated acids have a positive effect on brain activity, protect a pregnant woman from nervous breakdowns. Sea fish for expectant mothers should be alternated with freshwater.

For obese people

What can you advise losing weight, what kind of fish is healthy? For health, pollock and hake fillets can be recommended. It is also worth including dietary meat of saffron cod, cod and other types of lean fish in the diet. Especially tasty is such a popular product of Mediterranean cuisine as a sea wolf (another name for sea bass). 100 grams of this fish contains only 112 calories. Obese people often suffer from liver disease. In this case, they should eat halibut more often. The meat of this fish contains selenium - a substance that synthesizes antioxidants and protects the liver from free radicals. Tuna perfectly normalizes metabolism and thus also contributes to weight loss.

Fried fish: benefits and harms

This all-around healthy food can be a threat when it:

stale,
grown in an ecologically unfavorable reservoir,
infected with helminths.

It is equally important to know how to cook fish. After all, then you should take into account related products. Boiled fish is especially good for health. The benefits of a fried product are much less. After all, vegetable oil, when heated, begins to release carcinogens. But, on the other hand, fried fish has such an appetizing crispy crust ... No other type of product processing will do this. There is only one conclusion: you need to fry the fish in a non-stick pan without oil.

Fish is an indispensable product in a healthy human diet. The inhabitant of reservoirs won such respect and honor due to the content of omega-3 and omega-6 fatty acids in its composition, which have a “magic” effect on the human body. Experts and nutritionists often disagree on the “healthiest fish” category, since almost all of its species are saturated with beneficial trace elements and polyunsaturated acids (EPA and DNA).

The editors found out which fish is the most useful for adults and children, and also learned how to choose the right fish to get the most out of this product.

What is the healthiest fish?

The benefits of fish are difficult to overestimate for each person. This product is able to positively affect the functioning of the cardiovascular system, act as an effective immunomodulator and activator of the brain. Only 100 g of fish three times a week can significantly cleanse the body of "bad" cholesterol, help normalize metabolic processes and fat metabolism, improve thyroid function and at the same time saturate the body with high-quality protein without harm to a slim figure.

What is the healthiest fish for humans? The answers of nutritionists to this question are very contradictory - some call herring the “queen” among fish, others call trout, and still others see great benefits for the body only in tuna. The only thing experts agree on is that the most valuable varieties of fish are those that contain the most omega-3 and omega-6 acids.

The most useful fish with a high content of fatty acids:

wild salmon
Salmon and trout

The healthiest fish for humans

Despite the extensive list of the most useful fish that can be found on supermarket shelves, experts identify the best varieties that are indispensable in the healthy diet of every person. Nutritionists emphasize that the ideal “fishy” option can be chosen even for capricious gourmets and little “non-wants” who can’t stand the smell of fish even in the spirit.

Salmon

portal-culture.ru

Salmon is considered the "queen" among fish due to its useful and gustatory qualities. This variety of fish contains a large amount of omega-3 and omega-6 fatty acids, and also contains easily digestible protein and a “vitamin-mineral cocktail” of iodine, phosphorus, calcium, sodium, potassium, magnesium, fluorine and zinc.

100 g of salmon contains half of the daily protein requirement for the human body, but carbohydrates are completely absent, which is extremely important for a slim figure. Salmon is very useful for both men and women - the selenium contained in it significantly enhances reproductive functions in humans, promotes sexual desire and prevents premature aging of the skin.

It's important to know! Salmon is a rather expensive pleasure that not everyone can afford. Walnuts will be an ideal alternative to salmon , which are also an excellent source of Omega-3s.

Herring

neboleem.net

Herring is the most frequent guest in the kitchen of Russians, as it is a very affordable, budgetary and incredibly tasty variety of fish. Herring fell into the category of "the most useful sea fish" for a reason - it contains a large amount of useful, easily digestible protein and polyunsaturated fatty acids, essential amino acids and a number of vitamins.

Among the main beneficial properties of herring, nutritionists highlight the ability of this fish to have a beneficial effect on the nervous and digestive systems, stimulate the production of “good” cholesterol, and block the reproduction of fat cells.

Cod

poleznenko.ru

Experts refer this type of fish to the category of "the most healthy fish for children." This marine fish contains a lot of complete protein with an ideal composition rich in fatty acids. At the same time, cod meat is considered the most dietary and hypoallergenic.

Cod helps to strengthen the immune system, bones and teeth, oxygenate the brain. Moreover, this fish has a powerful anti-depressant property - one serving of cod significantly improves mood and helps to actively fight stress.

In terms of their composition, fish of the cod family do not differ much, therefore, silver hake, blue whiting, burbot, pollock and pollock will be an excellent alternative to cod.

Trout

poleznenko.ru

Trout belongs to the class of the most useful fish due to the fact that it lives exclusively in ecologically clean water bodies. The meat of this fish has a very tender and juicy structure, which is highly appreciated by culinary specialists. If you can’t decide which fish is the most useful, then trout will be an ideal option also because it can be bought live. This opportunity allows you to purchase a truly fresh and high-quality product that has not been frozen and “colored”.

Trout is especially useful in dietary nutrition - 100 g of this fish contains only 88 kcal, so it can be included in the daily diet in any amount, even with the most strict diet for weight loss. Trout is especially useful for pregnant women. Due to the content of a large amount of vitamin D and nicotinic acid (vitamin PP), trout contributes to the proper formation of the fetus and prevents abortion.

It is impossible not to note the high "rejuvenating" properties of trout - the regular inclusion of this fish in the diet allows you to visit beauty parlors less often and use expensive skin care products, since trout has a beneficial effect on the skin, smoothes wrinkles and moisturizes the epidermis, which is very important when developing the first signs of aging.

The most useful fish: how to choose?

Many negligent sellers very often turn even the most useful fish into a dangerous product, masking low-quality goods with the help of various tricks and tricks. How to "catch" the right fish in the store, which has not lost its priceless nutritional composition on the way to the counter?

iglinorb.ru

Quality red fish fed natural food has long fins and a pale appearance. If the fish has bright scarlet meat and small fins, then it was fed with growth stimulants and dyes.
"The fish goes out from the head" - the main indicator of the freshness of the fish are the gills. They should have a bright color and smell of fresh cucumbers. Dirty gray or pale gills with a pronounced fishy odor indicate that the fish is stale.
Clean, shiny and smooth scales are also a sign of high quality fish. In fish with a “difficult” fate, the surface is usually damaged, there are spots uncharacteristic of the fish variety, and the skin is easily separated from the meat.
The freshness of a fish fillet is easy to determine with one touch of a finger - after pressing on the flesh, fresh fish does not leave dents and does not release water.
Real red fish without dyes has white streaks. In the "tinted" product, the veins have an orange-red hue.

Fish is a product that is necessary for eating in order to maintain the beauty and health of the body. Fish contains more protein than meat. Among the wide variety of its varieties, it is not always easy to choose the most delicious and healthy.

Useful information

Nutritionists insist that fish should be included in the diet of every person. It contains substances that relieve joint pain in arthritis, reduce headaches, prevent the development of diabetes, help regulate blood pressure, and help reduce blood fat levels. Fish are rich in omega-3 fatty acids. They contribute to blood thinning, thereby reducing the risk of thrombosis.

Fish is a low-fat product. It is worth noting that even its fattest varieties contain only 25-30% of easily digestible fat. As a rule, fish protein is digested in the human body within 1.5-2 hours. Basically, fish are divided into sea and river. It is believed that the sea is also useful. But in both cases, there are pluses and minuses.

Sea fish

Sea fish meat contains a large number of substances useful for the human body: minerals (zinc, iron, lithium, boron, fluorine, bromine, phosphorus, copper, manganese, iodine, calcium, magnesium), vitamins (A, E, D, F), polyunsaturated fatty acids, amino acids (methionine, tryptophan, lysine, taurine). Thanks to this composition, fish is a favorite among dietary products.

Dishes prepared from sea varieties of fish are not only tasty, but also healthy. For example, consuming 100 g of this product daily can reduce the risk of cardiovascular disease.

The disadvantage of sea fish is its high cost compared to river fish. This is especially true for live aquarium and chilled fish.

River fish

One of the main advantages of river fish is considered to be its availability. It can always be purchased fresh near the house. Compared to the sea, freshwater inhabitants will be much cheaper. The meat of river fish also contains a large amount of useful trace elements. It is an excellent source of proteins.

However, the meat of river fish is considered less clean and tasty than sea fish. This is easily explained. River fish live in an environment most prone to contamination by heavy metals, pesticides and radionuclides. In addition, river fish is significantly inferior to marine seafood in terms of the content of useful amino acids, minerals and trace elements.

The most delicious and healthy fish

An important culinary advantage of ice fish is the absence of a smell characteristic of such a product. It is this property that makes it a good product for people who need it, but who cannot tolerate the fishy aroma. Icefish meat is very dense and lean (fat content is about 2-8 per 100 grams), but high in protein (17%). There are few bones in this variety: there is only a backbone, there are no costal bones and small bones. In addition, the ridge itself, due to its low calcium content, is very soft and edible.

Ice fish is usually cooked either steamed or boiled, but true connoisseurs of culinary masterpieces believe that the best dish based on it is aspic. The Japanese, knowing about the purity and environmental friendliness of ice fish meat, also like to eat it raw.

What is this fish and how is it eaten?

In fact, salmon fish does not exist. This is a generalized name for the salmon family, including salmon, chum salmon, trout, omul, etc. Each of these fish, however, is equally useful and has a similar chemical composition, supplying the body with very useful components.

Salmon red meat (the flesh of fresh fish has a pinkish tint approaching red) is very tender, quickly salted, does not deteriorate for a long time, but loses some of its properties during heat treatment. Therefore, to get the full benefit, it is recommended to use it in salted or smoked form, as an independent snack or in salads.

Benefits in every gram

Salmon contains omega-3 polyunsaturated fatty acids. They are not produced by the body, but come only with food, therefore they are especially valuable. With a sufficient content of these acids in the human body, the risk of cardiovascular diseases is reduced, hematopoiesis processes are normalized, the nervous system calms down, the active work of the brain is restored, and even. In combination with vitamin D, these acids rejuvenate the body and save from depression.

Of course, like every fish, salmon contains phosphorus and calcium, which strengthen the musculoskeletal system, teeth and nails. Potassium and magnesium, also contained in large quantities, stimulate the work of the heart, maintain muscle tissue in good shape. And all B vitamins work to maintain the immune system, contribute to a balanced production of hormones and cellular rejuvenation.

Salmon is part of various diets, because. gives a feeling of satiety for a long time. It maintains skin elasticity (thanks to zinc and vitamin A), improves hair structure.

The caviar of this fish is the most important source of nutrients. It is not inferior to salmon meat in terms of the number of positive effects on the body. It is caviar that contains a lot of lecithin, iodine, vitamins E, B, D, which normalize blood pressure and increase hemoglobin. There are no carbohydrates in caviar, and the amount of fat is reduced as much as possible. The "good" cholesterol contained in caviar is also needed by the body.

Salmon fat strengthens the walls of blood vessels and saves from diabetes. It, like aspirin, thins the blood, preventing strokes and heart attacks.

Women will surely appreciate all the benefits of salmon: it speeds up the metabolism, getting rid of cellulite. Collagen, which is part of the fish, preserves the youthfulness of the skin. And salmon protein will be a wonderful addition to nutrition with regular physical training.

Obviously, salmon is a must on the table in every home where health and longevity are sought.

Endangered bluefin tuna

According to statistics from the World Wildlife Fund, bluefin tuna, predominantly found in Mediterranean and Atlantic waters, may become extinct as a species in the coming years. The number of its populations is significantly reduced, and the capture is carried out exclusively by barbaric methods. The number of lovers of tuna and sushi salad is growing every day, while the tuna itself simply does not have time to multiply.

If sixty-four years ago, six hundred thousand tons of bluefin tuna were caught in the world, today this figure has already reached six million tons.

However, the problem is not only the lack of tuna to provide restaurants. Since tuna is a predatory fish, its disappearance from the marine ecosystem will upset its balance. Therefore, today many stars and the World Wildlife Fund are urging people to refuse tuna dishes. As a result, sixteen thousand people from one hundred and forty-nine countries of the world refused them, as well as some French, Italian, Norwegian, British and Spanish restaurants and shops. They have completely removed bluefin tuna from their menus and assortment.

By ditching the most expensive fish in the world, many restaurant owners are hoping that the tuna population will increase in the future as well as deli lovers.

Valuable species of fish

Ever since tsarist times, when fish soup was also called "gravy" and "slurry", this dish was divided into ordinary and festive varieties. The latter was also called "red ear" and "old fish soup", and for cooking they used valuable varieties of fish: sturgeon, beluga and salmon. Such a dish had a very appetizing amber color, and an additional aroma was given to it by then imported from distant countries, and now widely available saffron.

If you can’t afford to buy a whole fish from the Sturgeon or Salmon family, there is a fairly acceptable way out - you can purchase the so-called fish offal. It is they that are needed to cook the fish soup, and the rest of the fish - only for an additional “thickness” in the dish. Fatty and rich offal include the head of the fish, tail and trimmings of the abdomen. But even here there are some nuances of preparation. For example, you need to clean your head very carefully, since the presence of gills in it can impart excessive and completely unnecessary bitterness to an already prepared dish.

A great option is also a combination of sturgeon and salmon offal in one dish. Such an ear can become a real festive dish, worthy of literally the royal table. If you managed to purchase sturgeon offal, then be sure to peel the pieces of fish from the skin, as it can also impart a not very pleasant taste to the dish.

Other cooking options

Almost all types of fish that can be caught in Russian rivers are suitable for this dish: ruffs, whitefish, perches, pike perch, tench, burbot, catfish, ide, rudd, chub, carp, asp, bream and many others. At the same time, again, it is better to combine several varieties in one dish, since each of them gives the soup its own peculiarity. For example, it is believed that ruffs and perches impart stickiness to the dish, and burbot - sweetness.

If at least 3 varieties of fish are used in the preparation of fish soup, then it is called the “team”, and in the old days, not only the one that was cooked from “noble” raw materials was revered as a delicious soup, but also a dish in the preparation of which small fish were used.

But in general, for almost all variations, there are the same rules - in no case can you cook a whole fish, it must be gutted, washed and cleaned of scales; it is necessary to filter the broth after cooking; onions and carrots should be added to the broth at the stage of its preparation, which will give the liquid a pleasant aroma and not cloudy color.

Fish protein is best absorbed by the human body. This protein is healthier than meat. Marine goods can be bought at any store.

The ideal ratio of proteins and carbohydrates makes the dish dietary. Find out what marine fish are, look at the photo with the names.
