Let's see what are the beneficial properties of fish for humans, can it harm our health? Often these questions arise in people who care about their health and monitor proper nutrition. Let's weigh the pros and cons, but whether or not to use this product, everyone will have to decide on their own.

What is useful fish

A lot has been written about the benefits of seafood, but still, what is the use of fish? As you know, our body needs a balanced diet to function. That is, we must eat both proteins, and fats, and carbohydrates. But all these components must be useful, otherwise we will either receive less of the necessary substances from food, or consume them in excess, gaining excess weight in addition.

It is from fish that we get healthy fats: it contains omega-3 fatty acids, which are not only completely absorbed by our body, but also have a lot of positive properties, such as reducing the risk of cardiovascular diseases, developing memory, improving vision, repairing cells, preservation of youth and many others.

Phosphorus, contained in fish in the right amount, increases efficiency, increases endurance, invigorates and regulates the functioning of the nervous system. If you have been feeling tired and lethargic lately, perhaps your diet simply lacks fish? An easy way to test this is to boil your fish soup or make a tuna salad.

Sea fish contains iodine, which favorably affects the functioning of the thyroid gland. That is why sea fish is more popular than its river counterparts.

Literally all the inhabitants of water bodies, both salty and fresh, have meat containing high-quality protein. It can be compared to dietary chicken as it is easily absorbed by the body. And the fish contains valuable minerals: calcium, zinc, selenium, iron, phosphorus, magnesium.

Useful qualities of fish are also expressed in the fact that it improves the functioning of the nervous system, strengthens memory, normalizes the functions of the thyroid gland and metabolism, blood coagulation. Those who regularly use this product live long and retain sharp eyesight, strong nails and teeth until old age. Fish should also be eaten by healthy people - for the prevention of cardiovascular diseases.

The healthiest fish

Which fish is healthier than others? In fact, there is no single answer to this question. Those people who live close to the sea can be sure that they are buying fresh sea fish. But in supermarkets you can not always find good quality fish products. But this is not a reason to deny yourself fish dishes!

River fish is always on sale, and its price is much lower than sea fish. Therefore, we can confidently answer the question: “Which fish is healthy?” in a word - any! What matters is how you prepare it. After all, fish fried in oil can be too high in calories. It is better to bake slave steaks in the oven or use a double boiler to cook fish dishes.

As for the harmful properties of sea fish, they can be avoided if the fish head is removed before cooking - it accumulates all harmful substances from the water in which the fish lives. By the way, if your diet contains fish products, it has a positive effect on the skin and hair.

Another plus of eating fish is that it helps lower blood cholesterol, so it is an indispensable product for people with heart problems. To make up for the deficiency of iron in the body, you should eat not sea, but river fish.

A favorite among culinary specialists are salmon. These include salmon, pink salmon, chum salmon, coho salmon, chinook, sockeye salmon and trout. Salmon has the most valuable omega amino acids. Of marine fish, mackerel, notothenia, cod, halibut, rainbow trout, sardines, herring and tuna are highly valued.

Of the river species, pike, pike perch and perch are considered the most useful. The carp family (which also includes crucian carp and carp) contains a lot of easily digestible protein, as well as calcium, zinc, potassium and sulfur.

White tender perch meat is a dietary product. It has only 80 calories. In addition to low energy value, there are a lot of vitamins A, B, C, PP, E and D in perch. Pike is considered an excellent antiseptic, and it is prescribed for infectious patients to eat it.

Product health hazard

Even if we know how fish is useful, we must not forget that its valuable properties disappear from improper storage. Repeated freezing turns even the most valuable species into a worthless and even harmful product. An unfavorable ecological situation also directly affects the benefits of fish.

Mercury and other toxic substances tend to accumulate in the head and liver of the carcass. Fish are very often infected with helminths. And to protect yourself from worms, you need to subject the product to heat treatment.

Directly on the benefits of fish affects the method of its culinary preparation. A salty product can be dangerous for people with diseased kidneys. Hot-smoked fish is tasty, but accumulates carcinogens during such cooking.

Marine fish: pros and cons

Now let's talk about which product to choose. Let's start with the inhabitants of the seas. What fish is useful for is polyunsaturated fatty acids Omega-3 and Omega-6. These substances are not found in other foods. There are fewer amino acids in river fish. The meat of the inhabitants of the seas contains bromine and iodine.

They also provide us with much needed phosphorus. The mineral range of marine fish is much richer than that of river fish. There are molybdenum, cobalt, manganese, zinc, iron, copper, fluorine, sulfur, sodium, magnesium, potassium. Marine fish in terms of vitamin content are not inferior to vegetables and fruits. They contain the entire line B, as well as PP, A, D and H.

Fatty marine fish species are rich in arachidonic and linoleic acids. These substances are a necessary component of the cell membranes of the brain. The disadvantage of sea fish is their high price. Yes, and people living in the interior of the continent often have access to a frozen product, the nutritional value of which is lower than fresh, chilled.

River fish: pros and cons

Yes, the inhabitants of fresh water are inferior to their sea sisters in the number of amino acids. There is no iodine and bromine in them. But dieters know the benefits of fish. Extra pounds will not grow from it, there will be no indigestion or diarrhea from it. River fish is low-fat, and its meat is easily digested by the body.

In addition, this product is available to everyone. People living far from the sea can always buy fresh fish, freshly caught in a nearby river or lake. And this product - because it is available and available in large quantities - is usually not too expensive. However, there is one but. Fresh water bodies, especially ponds and lakes, are more polluted by humans. And the environmental situation directly affects the quality of the product.

Product hazard: poisonous fish

Here you need to isolate several types of dangers to humans. There are poisonous fish such as puffer or brown puffer. Only licensed chefs can cook them: one slip and dinner can be fatal. Fugu accumulates so many toxins in its meat that it can kill a person within one minute.

Other types of fish are not so deadly, but can also cause discomfort - indigestion, diarrhea. These include the Crimean barbel, triggerfish, hedgehog fish, barracuda, sea pike, madder. But there are some types of useful fish that have poisonous body parts.

You should carefully and carefully remove the gills from them, wash off the mucus, select the bones, etc. Sturgeon can serve as an example of such a delicacy. He has valuable meat, but a screech that is dangerous for humans - a vein that runs along the ridge.

Fish is a dietary product

Fish dishes are indispensable if you plan to stick to a diet. Since it has a high protein content, but at the same time low calorie content, eating fish, it is easy to get rid of excess weight.

Do not forget that the more varied your table is, the more useful substances you will get! It is not necessary to constantly buy the same fish - experiment and discover new options for a quick and easy dinner.

Despite its lightness, due to the high protein content, a fish dinner will be quite high in calories, but these will be “useful” calories. During cooking, meat loses 40% of water, and fish only 20%. Therefore, fish dishes delight with their softness and juicy taste.

Knowing which fish is the most healthy for a person, you can compose your menu so that it definitely has a place for a fish dinner at least once a week. Although it does not matter which fish is healthier, because it is not necessary to constantly buy only expensive sea fish, river fish also have a lot of vitamins and beneficial properties of fish.

Months when you can not eat fish

On the eve of summer holidays, do not forget to treat fish and seafood with double caution. Especially to those that you buy in the markets and order in coastal restaurants.

Remember the old adage that you shouldn't eat fish in months that don't have the letter "r" in their names? Of course, you should not take it to heart and deny yourself a fish for the whole of May, June, July and August. But it doesn't hurt to be vigilant. Remember that the already short shelf life of fresh fish during the summer heat decreases significantly, and catering establishments, market sellers and even large supermarkets often ignore this fact.

Now that you have a list of the healthiest types of fish, it's time to go shopping and adjust your menu. Be always healthy!

82% Behind

Should you include fish in your regular diet? Yes, because it is in no way inferior to meat - and some types of fish even surpass it - in terms of protein content. A whole set of vitamins, macro- and microelements is also in favor of a positive answer. And, of course, the fats in the composition of fish (85% of them are unsaturated acids) are more easily absorbed by the body.

Taste qualities 87 %

Benefits for the body 95 %

Security 63%

"Meat is unhealthy" - such a statement is increasingly being heard today from the lips of expert nutritionists and many reputable doctors.

Yes, indeed, animal protein in large quantities can cause a variety of diseases.

But! No one will argue that a steak is very tasty, right? And what should gourmets, lovers of dense and high-quality food do, if it is better to avoid meat? Is there an alternative?

Of course, the same doctors and nutritionists answer - this is a fish! No less appetizing, but a hundred times more useful than meat and at the same time a complete benefit for health.

Fish fish strife

Fish is a valuable and sought-after, and for many also the most favorite food product. From it you can cook a lot of delicious, tender, easily digestible, delicious, healing dishes.

And more and more people are ready to eat fish not only on the same "fish" day - Thursday, but much more often.

If you ask yourself the question: which of the fish is the most useful, then there will be only one answer - the sea! And fat and caught in the wild.

Why not river? Because the state of river ecosystems, especially shallow ones and those that flow near human habitats, is catastrophic. They are dirty and lifeless.

The “diagnosis” of the waters of the oceans is not much more comforting, but there the highest concentration of harmful and destructive substances is observed for the most part along the coastline.

Fishing, on the other hand, is usually carried out in deep water, far from the coast, so the catch has a satisfactory ecological cleanliness.

Another unpleasant thing for a person who wants to eat right and healthy is the fact that the fish that fills shop windows and market stalls, despite its outward appeal, is far from healthy.

All this is an assortment of fish farms engaged in artificial breeding of different varieties of fish.

For fattening such fish, growth stimulants, dyes, antibiotics, hormones and other components that are terrible for the human body are used.

In this regard, you need to be very well versed in fish, so that in an effort to get the most useful, you do not have to pay for a synthetic salmon carcass.

What is the most commonly farmed fish?

1. All types of sturgeons, since most of them are included in the Red Book lists and there is no such catch in the wild.

2. Almost the entire list of salmon fish, and especially trout and salmon.

3. Dorado fish.

4. The famous sea bass (it is also on the lists prohibited from catching in nature).

5. Carps, carps, silver carps - although not sea fish, they are tasty and fatty, but, unfortunately, they are also grown on artificial feed.

6. The lion's share of seafood (mussels, shrimp, scallops, lobsters with langoustines, oysters).

7. Telapia fish and pangasius fish. About them in general separately. Not only are these types of fish already considered scavengers and scavengers, they have also begun to be bred in industrial aquariums.

Moreover, for the growth rate and weight gain, they are treated with male sex hormones.

Fish that are still wild

You don't have to worry in advance. There are still a lot of wild fish left in nature, which will decorate any table and be a panacea for your health.

Here is a list of those inhabitants of the deep sea, which, for various reasons, were not taken into circulation by fish farms.

1. Cod- a very healthy and tasty fish with a unique huge liver, from which fish oil is made. Cod cleans blood vessels, restores nervous balance, gives energy, is good for the heart.

2. Far Eastern representatives of salmon- this is whitefish (as well as its caviar), pink salmon, sockeye salmon and chum salmon. They are caught in the cold waters of Kamchatka, near Sakhalin and the Kuril Islands.

It is believed that fish, whose habitat in low-temperature seas is the most useful, contains a lot of those very essential amino acids, for which it is worth eating.

3. Close relatives of cod, although not so tasty, but definitely useful and do not grow in captivity - this is a people's favorite pollock, and hake, whiting, capelin(the most useful fish for female beauty and youth), sardine.

4. saury- large inexpensive commercial fish. It is not scarce, and this makes it even more valuable, since absolutely everyone can introduce it into their diet.

5. Of course herring And mackerel. Both are absolutely wild. Fatty, tasty and inexpensive. Pay attention to them more often, eat and be healthy.

6. Fish flounder also never grew in captivity. It makes amazing cutlets - tender and juicy, especially steamed.

An interesting fact is that it has more than salmon! It is considered the best product for those who need a quick recovery after a long treatment.

7. Perch and pike are freshwater competitors of marine fish. Of the river inhabitants, they are the most useful.

By choosing any of the listed fish, you can be sure that it has not been raised in captivity.

However, be careful about the quality of the product, as already caught fish can be treated with chemicals, pumped up with water, tinted, re-frozen and thawed.

Remember: wild fish always have large fins and unevenly colored meat.

Do not buy fillets separately, it is better to take a carcass and remove the pulp yourself. Give preference to young, small-sized individuals, they do not have time to accumulate harmful substances in the water.

Baking and steaming work best as heat treatments to preserve the benefits.
