Fish is a good source of complete animal protein. In this regard, it is in no way inferior to meat. As a source of fat, fish is more beneficial to humans than meat and dairy products. So, if “fish” fats prevent the accumulation of cholesterol and the development of atherosclerosis due to the omega-3,6 fatty acids contained in them, then saturated fatty acids and cholesterol, contained in a large amount in other animal products, on the contrary, only contribute to this.
Doctors advise to include fish dishes in your diet at least 3 times a week. Moreover, the river and sea representatives of this biological superclass are recommended to alternate, since they contain different sets of useful substances.
The benefits of marine fish for humans
Sea fish, like other gifts of the oceans, contains a significant amount of iodine, necessary for the thyroid gland to work. It is a source of manganese - a trace element, the lack of which can lead to a weakening of immunity, pain and muscle cramps, memory impairment.
In addition, fish living in the waters of the cold seas contain many omega-3 fatty acids, which reduce the likelihood of heart attacks and strokes. Sure the first place on the content of these nutrients is red fish, especially salmon, the use of which in the food is confirmed by some statistical data. It is noted that the death rate from heart attacks and strokes in Greenland and Iceland, whose diet is based on this particular fish, is only 3%, while the average death rate from these diseases in Europe reaches 50%.
The benefits of river fish for humans
The use of river fish is its easy digestibility - it is absorbed by 92-98%, while meat is only 87-89% - therefore, boiled or baked fish is often recommended for people with diseases of the gastrointestinal tract. It has relatively few calories 120-150 calories per 100 g, a lot of high-grade protein, as well as vitamins A, D, E. River fish has a large amount of phosphorus and potassium compounds that are completely absorbed by our body, strengthening bones and preventing the development of osteoporosis.
In this way, both sea and river fish are able to benefit, no matter which variety you choose.
What vitamins are contained in fish?
In this regard, fish is also not inferior to many foods known to humans, it is rich in vitamins A, D, G, vitamins of group B, they must be ingested with fats, some are not absorbed without them.
The whole fish is divided into 3 groups: low-fat, medium-fat and oily. For example, carp and goby are low-fat fish, but salmon and saury are fatty fish. The more fat the fish contains, the more vitamin the body can get from eating it.
In addition to the vitamin content, it is also rich in valuable minerals: calcium and magnesium, which affect the healthy appearance of hair and nails, phosphorus, which is actively involved in energy metabolism, as well as fluorine, copper, zinc and potassium.
The undeniable benefit of marine fish, of course, is the high content of iodine, which is so necessary for the normal functioning of the thyroid gland. Also in the caviar of sea fish contains a considerable amount of iron, it is often recommended in the diet, as well as iron deficiency anemia.
As for the benefits of river fish, it is somewhat lower, since sea fish is fatter than river fish, therefore the content of such beneficial omega-3 fatty acids is lower. But at the same time, it is the river fish that is the main supplier of easily digestible protein into the human body. That is why river fish can be an excellent dietary product that can be safely used by people who are struggling with excess weight, and also have diseases from this area.
How to choose and cook a healthy fish?
The taste and usefulness of fish depends not only on its variety, but, in many respects, on the conditions of its habitat, food, spawning period and, of course, the conditions of its storage. It is best to purchase fish in specialized fish stores, where a qualified specialist will be able to advise you on a particular type of fish.
Buying fish on the market can be dangerous, as a rule, control over the quality of the product is lower there, and the level of honesty of the sellers is also very different. The main reason for the deterioration of fish products and the loss of their original quality is the repeated freezing of the product. It is best to buy live or chilled fish, in extreme cases - frozen "in the glaze", which means the presence of a light crust of ice, which is applied in a special way to the fish.
The main criteria for high-quality and fresh fish:
- Pay attention to the gills, in fresh fish, they should have a scarlet or burgundy color, but not gray or black.
- Fresh fish should not have a muddy look.
- The flesh of the fish should be firm and dense, without bluish or purple spots. When you press your finger on the carcass, the flesh must quickly return to its original shape. The meat of high-quality red fish should not have a yellowish tinge, and the white meat - dirty gray. Such shades speak about repeated frosts of fish.
There is an opinion that the most useful fish is an expensive fish, but this is not the case. Fish that are at the bottom of the food chain, that is, they feed on zooplankton, will be absorbed by the body much easier than rare and valuable specimens of predatory fish. Although among fish lovers of zooplankton there are expensive and rare species.
What is the most useful fish?
The question immediately arises: which of the most popular and consumed fish is the most useful? The question is difficult, but we will try to give a few examples. Among salmon species, it is believed that trout and salmon are the most useful, they are able to slow down the aging process of the human body, and also carry out the prevention of cardiovascular diseases.
If you turn to cod, then cod, pollock, hake and haddock are useful, they are considered the most dietary fish species, and also very useful for pregnant women and expectant mothers.
Also useful are herring and sardines, which are considered to be among the most nutritious fish (33% fat), which contributes to the content of large amounts of vitamins. And here, for example, pike is a very dietary product, it contains only 3% fat. Carp and crucian carp are very useful among carp, they help to strengthen the musculoskeletal system, and also have a beneficial effect on the health of the skin and mucous membrane.
As you can see, each fish is useful and unique in its own way, therefore, it is necessary to choose which one is best to use exactly in your case, depending on your personal needs. But with regard to the method of preparation, the most useful and safest way for health is grilling, as well as options for dishes where the fish is baked and stewed.
In order for the fish to be able to enrich the human body with its nutrients and vitamins, as well as to maintain this process at the proper level, it is necessary to use it 2-3 times a week, alternating between river and sea fish.
Useful properties of fish
Fish fillet is a source of easily digestible protein, trace elements, vitamins, but the most valuable in fish is fat, which consists of polyunsaturated fatty acids (omega 3 and omega 6) and is completely absorbed by the body.
Speaking about the benefits of fish, it is worth focusing on which fish is healthier: river or sea. In river fish or fish from freshwater bodies of water, the content of protein and fat is less, it does not contain iodine and bromine, which are always present in the composition of marine and oceanic fish.
The use of fish harvested from the depths of the sea, of course, more than the benefits of fish caught from the nearest river. Sea fish, besides being rich in iodine and bromine, nourishes our body with phosphorus, potassium, magnesium, sodium, sulfur, fluorine, copper, iron, zinc, manganese, cobalt, molybdenum. The vitamin series contained in sea fish fillets is significant, these are the B vitamins (B1, B2, B6, B12), vitamin PP, H, in insignificant amounts vitamin C, and also fat-soluble vitamins A and D.

For older people and children, this food will be indispensable, since it is absorbed in 2-3 hours. If you compare with other products, for example, it takes about 6 hours to digest meat.
The energy value of fish is higher than meat. Some of its representatives are 20% composed of protein, a protein containing 17 amino acids necessary for the body. What else is useful fish? It is enriched with fish fats. For example, it includes omega-3, which have many positive properties: improvement of the arteries, protection against the appearance of blood clots, due to which a heart attack or stroke can occur.
In addition, what is useful fish for humans? The product is necessary for people who have high blood pressure. The omega-3 component is essential for normal brain and eye function. With it, inflammation in the human body is prevented, cholesterol in the blood is reduced.
What is contained?
Fish contains vitamins A, D, G, B. The product is low-fat, medium fat, and fatty. For example, carp and goby belong to the first group, and salmon and saury - to the third. The more fat is contained, the more vitamins enter the body.
In addition to vitamins, the product is enriched with valuable minerals. These include calcium, magnesium, which are required for a healthy-looking hair and nails. Phosphorus is required to participate in energy metabolism. Minerals include fluorine, copper, zinc and potassium.
A huge benefit of marine fish is the high content of iodine, which is required for the normal operation of the thyroid gland. This component is in caviar, so it is used in diet and anemia.
The most useful fish - sea. The river product contains less valuable omega-3 fatty acids. But it includes the necessary, easily digestible protein that everyone needs. Therefore, river dwellers are recommended for diets, as they are suitable even for those who are struggling with overweight.
Choosing a quality product
Taste and benefits are determined by the variety and habitat of the fish, spawning period and storage conditions. It is advisable to buy it in specialized stores, where sellers advise on a certain type of sea or river dweller.
It is dangerous to acquire products on the market, because the quality control is lower there, and the honesty of the sellers is different. The main reason for the damage of such goods is considered to be repeated freezing. It is advisable to choose live or chilled fish, but ice cream “in the glaze” will also be suitable when the product is covered with a light crust of ice.
The following rules will help you choose high-quality and fresh products:
- It is necessary to pay attention to the gills: in fresh products they are scarlet or burgundy, but not gray or black.
- Fresh sea and river inhabitants do not have a muddy look.
- The flesh should be firm and dense, without blue and purple spots. When pressed it is important that she returns her form. The meat of the red varieties of marine life should not be with a yellowish tinge, and the white type - grayish. These signs indicate multiple frosts.
It is believed that the most useful fish is expensive, but it is not. Zooplankton dwellers inhabit the body more easily compared to rare and valuable predators. What is the most useful fish for a person, described in the article.
What fish is good for humans? There is no unequivocal answer to this question, since many inhabitants are of value to human health. Of the salmon, trout and salmon are considered the most useful. They slow down the aging process of the body, serve as prevention of heart and blood vessels diseases. If cod is taken into account, it is preferable to choose cod, pollock, hake, haddock. These are dietary foods that are especially beneficial for pregnant women.
What kind of sea fish is useful? She also takes herring and sardines. These foods are considered nutritious (33% fat). A pike is dietary, because it contains 3% fat. Carp and crucian carp, which strengthen the musculoskeletal system and have a positive effect on the health of the skin and mucous membranes, are considered to be beneficial.
Therefore, it is impossible to say for sure what is the most useful fish for humans. It should be chosen at will. The safest method of cooking is grilling, as well as baking and stewing. It is necessary to consume the product 2-3 times a week, alternating between river and marine species.
It should be borne in mind that sea and river inhabitants also have a negative impact. Only those organisms that have grown in natural water bodies not polluted with industrial waste are useful. Fish can live in harmful water, it absorbs all the poisons. The harm is as follows:
- Salts of heavy metals were often found in tuna and salmon meat. It includes lead, cadmium, arsenic, strontium. These components are dangerous to humans.
- In the adult individual contains a lot of poisons. On packages in stores usually do not indicate the age of seafood.
- Rarely in any fish farms products really high quality. Weight is increasing biochemical additives. For sale are used and sick individuals.
What consequences does a person expect when eating sick fish? The negative sides are as follows:
- Salts of heavy metals adversely affect the kidneys, adrenal glands, ovaries.
- If the individuals are highly infected, they can affect the development of oncology and infertility in men.
- Because of old fish, the blood composition deteriorates, metabolism and hormonal system are disturbed.
- The consequences include stomach irritation, dysbacteriosis, diarrhea.
In frozen form, it is almost impossible to recognize that the fish is sick. But be sure to look at the expiration date. You also need to pay attention to the belly: it should be light. You should not take products with yellowness. It is advisable to purchase a peeled fish. Many harmful components are found in the intestines. And during storage, the poisons enter the meat.
Thus, the fish is useful only if it is fresh and caught in clean waters. Then it is suitable for use. A spoiled product will not benefit.

Contraindications to consumption
Like any product, fish is not for everyone. Eat it should not be in such cases:
- The presence of allergies. Since the "meat" of marine life contains a large amount of protein, it often provokes negative manifestations in people who are hypersensitive to this component.

In these situations, marine fish can cause significant harm to the human body and significantly impair its health.
Sea fish: possible harm to the product
In some cases, sea fish can also harm a healthy person even in the absence of any contraindications to its use. This product may lose its beneficial properties under the influence of the following factors:
– Water pollution. Every year the ecological situation in the world is only getting worse; tons of industrial waste, including quite toxic, are dumped into the seas and oceans.
Underwater inhabitants absorb harmful substances, as a result of which marine fish may contain mercury, cadmium, lead, arsenic and a number of other dangerous elements that can cause significant harm to human health, which eats such a product.
– Disease fish. Sea water is the habitat of a number of dangerous bacteria and worms that parasitize in the body of fish. When eating sick individuals in food is likely to be infected.
– The use of chemicals for growing. When marine fish are found in a firm, hormonal compounds that stimulate rapid growth are often used. The components of these substances remain in the organs and tissues of individuals and are often dangerous to humans.
– Freezing and subsequent defrosting. In areas remote from the coast, it is impossible to purchase fresh sea fish, during long shipments the product is subjected to freezing, and often this happens repeatedly. As a result, the "meat" of marine life loses most of the nutrients.
In other words, fish grown under adverse conditions or repeatedly frozen and thawed, at best, lose their beneficial properties, and at worst - harm the human body.

How to choose a fish?
To eat marine fish does not harm the body, you should know how to choose it correctly. Before you make a purchase, you need to pay attention to the following points:
– A store. Like any product, fish is better to buy in large supermarkets, and not “from the car” near the metro station or bus stop. This is due to the fact that in the first case, the goods pass sanitary inspection and are usable, and questionable outlets are not responsible for the quality of the products.
– Fish size. The larger the individual, the older it is, and when the hake or pollock was caught in ecologically unfavorable areas, it absorbed a lot of harmful substances during its life. For this reason, carcasses of small and medium size should be chosen, since the young fish contain less toxins than the inhabitants of the seas of old age.
– Eyes individuals. If the fish is of high quality, the eyes will be clear and shiny, and the presence of spots and opacities on the mucous membrane indicates a doubtful freshness of the product.
– Gills. The respiratory organs of both a healthy and recently caught individual have a dark red color and a uniform surface, and the presence of mucus on them indicates that the inhabitant of the seas left her water reservoir a long time ago.
- Leather and Scale. On the body of the fish a certain amount of mucus is allowed, which should be colorless and have no foreign odors. Otherwise, the consumption of such a product threatens to poison.
– The elasticity of the carcass. With a slight squeezing on the body of the fish should not remain traces or dents, fresh and high-quality product is characterized by the ability to quickly regain its shape.
After the acquisition of the carcass should be another "test for freshness" at home. To do this, lower it into a bucket of water. If the product is fresh, then the fish will remain at the bottom, and in cases where it was caught for a long time, the body will immediately emerge.
To get the most out of sea fish, it is important to combine it with other products. Best of all, vegetables and mushrooms are suitable for salmon, catfish, tuna and other varieties, and the lemon sauce will add a unique taste and savor to the dish.

The use of pike for a balanced diet is also in the fact that the fish contains a large amount of natural protein, which is well absorbed by the body and saturates it with useful micro and macro elements.
The benefits of fish in the life of a person on the face - this is good health, strong immunity, sound and careless sleep. You should not buy expensive medications to prolong your life and heal, it is enough to eat right. Fish will help you with this, its diet is varied. From a large number of dishes you will certainly find something for yourself.

What is the most harmful and dangerous fish?
If you have not heard about junk fishes, such as the telapia and pangasius, then you should know that they feed on the most terrible waste and are forbidden to use in many countries.
These fish even eat old shoes, rot, feces, dwelling in the ponds.
For example, in Vietnam, Telapia lives in irrigation canals near rice paddies. Sewage drains flow directly into these canals, while local villagers dispose of household waste, simply slop.
Have you ever wondered how to remove bones from fish fillets? Do you think mechanically?
No not always. It happens that they are dissolved with a special chemical solution, and so that the fillet has a beautiful presentation, it is filled with water, salt, polyphosphates, dyes, ammonia, and a lot of chemicals.
In general, I will not continue further, all this can be found and viewed on the Internet.
What is useful for human health fish?
But, before voicing the most useful fish, I want to say a few words about why experts always recommend eating fish at least three times a week.
So, what is useful fish in human nutrition:
- Important fatty acids in fish
I think that many people know that our body needs to continuously receive two essential polyunsaturated fatty acids - alpha-linolenic acid (OMEGA 3) and linoleic acid (OMEGA 6).
These acids are not synthesized by our body, so we must definitely get them from food.
In more detail about what these acids are useful and in what products they are contained, I told here
- Essential Fatty Acids
But, there are also two more OMEGA 3 fatty acids, which are also vital for our body: eicosapentoenoic acid (EPA) and docosahexaenoic acid (DHA).
These acids are not interchangeable, they are very necessary for our body and are mainly in fish!
This is one of the main factors that indicate why eating fish is so beneficial.
The number of OMEGA 6 to OMEGA 3 in our body should be approximately equal in proportion!
But, in fact, in practice, we use in much more OMEGA 6 due to the fact that they are more common in products 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 must eat products that increase the proportion of OMEGA 3 and reduce the proportion of OMEGA 6. And most of all OMEGA 3 contains fish.
On this basis, the World Health Organization (WHO) recommends eating two or three fish dishes a week.
Fish is the richest source of vitamins and trace elements, it is vitamin A (retinol), potassium, phosphorus, iodine, sulfur, which are necessary for our eyes, brain and joints.
What is the most useful fish?
So, what is the most useful fish?
I searched for the answer to this question in very many sources.
As always gathered a sea of conflicting information. Some nutritionists put herring in the first place, others trout.
A number of experts have recognized tuna as the most useful fish, while others have rejected it from the ability to accumulate mercury in large quantities.
Therefore, in order not to mislead myself and others, I decided to confide in the opinion of an authoritative specialist, doctor of medical sciences, professor of healthy and sports nutrition, Suzanne Kleiner, who share most of the well-known nutritionists.
So, the most useful fish is the one that contains the most OMEGA 3 acids!
Most of them can be found in the following types of fish (arranged in descending order):
- Wild salmon
- (all fish of the salmon family, and this is all Atlantic salmon - salmon and trout and Pacific salmon-chinook, salmon, sockeye, etc.)
- Rainbow trout
The most useful fish
The most optimal balance of OMEGA 3 to OMEGA 6 has salmon, besides the amount of EPA and DHA in salmon is perfect!
The daily dose of omega-3 fatty acids is 85 milligrams
This dose is only 100, 0 salmon!
And given that these acids are able to accumulate in the body, eating salmon in large quantities than 100, 0, three times a week, will provide all the necessary concentration of OMEGA 3 in our body.
Conclusions and important facts
We conclude that the best fish is wild salmon (all representatives).
Remember that salmon, as well as trout, is a collective image that combines all the fish of the salmon family.
An alternative to salmon can be just two products - walnuts and flaxseed.
Both of them are excellent sources of omega-3, but they cannot be compared with salmon in their usefulness, because their omega-3 fats exist in the form of alpha-linolenic acid (ALA), and not EPA or DHA, which are considered the most valuable.
As a result of clinical trials, people who consume salmon daily for a month have noticeably improved their skin, blood vessels, blood composition, and overall body condition.
10% had joint pains completely.
Very important fact!
But, it is worth noting another very important fact. Not all salmon, like other fish, can be helpful.
All of the above applies to fish that grew in the wild in ecologically clean waters (Pacific Ocean, Sea of Okhotsk), and not in artificial reservoirs.
By the way, for me it was a shock that any fish grown artificially can be “painted” in any shade. You want, you will grow trout with red meat, with orange, with yellow, with golden.
Tasty but harmful
So, for example, in the opinion of pangasius, tilapia and pollack, nutritionists are almost unanimous. This fish practically does not represent any special value. Moreover, the first two species contain poorly digestible fats.
In addition, most of this fish is brought to us from Vietnam, and the conditions for growing tilapia and pangasius are far from the norms adopted in our country and in Europe.
These types of fish easily accumulate mercury and other harmful substances from the environment.
Pollock is ideal for those on a diet. A large amount of protein and iodine makes this fish useful. However, when cooked, this fish loses most of its value.
And the taste of pollock is still an amateur. This fish is rather dry, so it’s best to cook it with sour cream or mayonnaise.
The availability and prevalence of this fish allows you to cook it in a variety of types.
Cod and halibut
These types of fish are among the most popular and beloved nutritionists around the world. Dense cod meat is rich in protein and fatty acids, indispensable to the human body.
And the vitamin composition of meat and liver is close to modern multivitamin preparations. With all this, the caloric content of cod is only 85 kcal per 100 grams. This makes it an indispensable product in the diet.
The only thing worth remembering is that over consumption of cod liver oil can cause digestive problems. Therefore, everything is good in moderation.
Halibut is a pantry of the most beneficial trace elements. Selenium, potassium, zinc and phosphorus are found in the meat of halibut in a rather large amount, as compared with other types of fish. Halibut is a very fatty fish, so people with gastrointestinal diseases or liver diseases need to eat this fish very moderately.
Herring and mackerel
These are perhaps the most popular guests on our table. Few people have never in their life tried “herring under a fur coat” or smoked mackerel. With all its availability, it is also one of the most useful varieties of sea fish.
The variety of ways of cooking herring and mackerel also attracts by the fact that any way of processing and eating almost does not change its vitamin-mineral composition and nutritional value.
Simply put, herring and mackerel are good and useful both in the form of cold appetizers and in smoked form. The only exception is, perhaps, canned fish, since
With this treatment, the fish loses the most valuable - Omega-3 and Omega-6 fatty acids.
Norwegian Salmon is a global brand. Why exactly Norwegian? Yes, because the more north a fish lives, the more valuable its "fat".
Salmon fish is of particular value for people of age and those who have problems with vessels. Fats of this breed of fish are practically not deposited on the walls of blood vessels in the form of harmful cholesterol.
A rich range of B vitamins prevents diseases of the nervous system.
The ideal salmon preparation is to buy fresh or properly frozen fish, cut it up and pickle it yourself. Because heat treatment changes the taste of fat and destroys the valuable vitamins and minerals contained in red meat salmon, chum, trout. One of the significant disadvantages of salmon fish is its high cost.
The main thing to remember when eating sea fish is one of the most allergenic products, so a too abrupt transition to the “fish diet” can do more harm than good.
