- Fresh sea and river inhabitants do not have a muddy appearance.

"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 the windows of shops and market stalls, despite its external attractiveness, 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 others are used, which are terrible for human body Components.
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- very helpful and delicious 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, as well as 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! She is considered 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.

I.e The benefits of fish are undeniable.
But! The fish possesses the described useful properties only if it lives in natural conditions, spawns at the time set by nature and is not subjected to regular “attacks” by humans.
Why can fish be harmful?
The benefits and harms of fish are determined by a similar characteristic - her rich composition. The health benefits of a variety of natural components of the fish body. And the harm is explained by the ability of the fish to absorb all the poisons and harmful substances that are contained in the water.
Imagine how many of them can accumulate if waste is regularly dumped into water bodies!
In addition, in fish living in harmful dirty water, salts of heavy metals accumulate. For example, salts of cadmium, chromium, lead, arsenic and other radioactive substances (eg strontium-90) often accumulate in tuna and salmon. And it is the salts of these elements that can have a detrimental effect on human health.
Also, the benefits and harms of fish are “combined” the age of the fish. The older the fish, the more different elements accumulate in it.
Useful substances weaken with age. BUT harmful substances quite a lot can accumulate in fish. Accordingly, and the harm from eating old fish can be quite severe.
In addition to the state of the water harmful properties fish are affected by the conditions in which the fish are kept.
Except rivers, lakes, seas a large number of fish hits the counter from the so-called "fish farms".
And do you know that fish feel pain? And what is it like for her, poor thing, to be in such habitats? Especially since infections and diseases- a fairly common occurrence for such "fish farms".
Undoubtedly, such fish benefit is much less than harm.
What harm can a sick fish do?
Eating sick fish can have a very negative health impact. For example:
- Strontium-90, cadmium and other heavy metals can harm kidney function adrenal glands and, what is the saddest thing, ovaries;
- A large number of harmful substances can cause infertility in men;
- Severely infected fish can provoke cancer of various organs;
- Old sick fish spoil the blood, disrupt metabolism and provoke hormonal failure;
- Infected fish are very easy poison and cause irritation of the gastrointestinal tract. Especially if you buy fish ready to eat.
Especially dangerous sick fish for pregnant women. Such fish not only does not bring benefits, it is harmful to the health of the unborn child, negatively affects its development, and can provoke physical and mental disorders.
And even the so-called "fish phosphorus" may not have the proper effect on the body if there are a lot of other harmful and difficult to digest substances in the fish.
It is sad that both benefits and harms from fish can be quite a lot. And the site site recommends that you seriously think about such an important issue.
