Surely many have heard that fish is a useful product that must be eaten as often as possible. No wonder our grandmothers and mothers were stuffed with fish oil throughout childhood, not paying attention to the fact that it is "tasteless and disgusting."

However, most likely, few people know why fish is so useful, how much it must be consumed in order for all the usefulness to get down to business and enrich our body.

First of all, we will cite a lot of useful fact: fish is an easily digestible product that does not leave heaviness in the stomach, and also contributes to good and easy health. Of course, people with absolutely healthy intestines and stomachs can be surprised, they say, what's the difference, how much is there and what will be absorbed.

But for the elderly, as well as for children, people with stomach problems, fish can become an irreplaceable food product, because it is absorbed in just 2-3 hours. If we take meat as an example, then the process of its assimilation can take up to 6 hours!

But fish is in no way worse than meat, on the contrary, its energy value is even higher. Some fish representatives may be 20% protein, a very valuable protein that contains all the 17 amino acids necessary for the human body, and in ideal proportions. And this is not all that fish is useful for.

The composition, for example, includes the well-known omega-3 fatty acid, which has an endless list of benefits: it favorably affects the health of the arteries, and also prevents the formation of blood clots that can clog arteries and lead to heart attack or stroke.

In addition, it is necessary for people who suffer from high arterial. In addition, omega-3 contributes to the normal functioning of the brain and eyes, prevents inflammatory processes in the body, and also helps to overcome them, helps to reduce blood cholesterol levels.

What vitamins are found in fish?

In this matter, fish is also not inferior to many food products known to man, it is rich in vitamins A, D, G, vitamins of group B, they must enter the body along with fats, some cannot be absorbed without them.

All fish are divided into 3 groups: low fat, medium fat and fat. For example, crucian carp and goby are low-fat fish, but salmon and saury are fatty types of fish. The more fat a fish contains, the more vitamin your 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 indisputable benefit of sea fish, of course, is the high content of iodine, which is so necessary for the normal functioning of the thyroid gland. Also, the caviar of sea fish contains a considerable amount of iron, it is often recommended in dietary nutrition, as well as in iron deficiency anemia.

As for the benefits of river fish, it is slightly lower, since marine 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 river fish that is the main supplier of easily digestible protein to the human body. That is why river fish can become an excellent dietary product, which can be safely consumed by people who are struggling with obesity and also have diseases from this area.

How to choose and cook 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 from specialized fish stores, where a qualified specialist can advise you on a specific type of fish.

It can be dangerous to buy fish on the markets, as a rule, the control over the quality of the product is lower there, and the level of decency of the sellers is also very different. The main reason for the deterioration of fish products and the loss of their original quality is repeated freezing of the product. It is best to buy live or chilled fish, in extreme cases - frozen "in 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 quality and fresh fish:

• Pay attention to the gills, in fresh fish, they should be scarlet or burgundy, but not gray or black.
• Fresh fish should not have a cloudy look.
• The flesh of the fish should be firm and firm, without bluish or purple spots. When you press your finger on the carcass, the pulp should quickly return to its original shape. The meat of high-quality red fish should not have a yellowish tint, and the meat of white fish should not be dirty gray. Such shades indicate multiple frosts of fish.

There is an opinion that the most useful fish is an expensive fish, but this is not at all the case. Fish that are at the bottom of the food chain, that is, they feed on zooplankton, will be assimilated by the body much easier than rare and valuable specimens of predatory fish. Although there are expensive and rare species among fish lovers of zooplankton.

What is the healthiest fish?

The question immediately arises, which of the popular and consumed fish is the most useful? The question is complex, but we will try to give a few examples. Among the salmon species, it is believed that 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 we turn to codfish, then pollock and haddock are useful, they are considered the most dietary types of fish, and are also very useful for pregnant women and expectant mothers.

Also useful are herring and sardines, which are considered one of the most nutritious fish (33% fat), which contributes to the high content of vitamins. But, for example, pike is a very dietary product, it contains only 3% fat. Among cyprinids, carp and crucian carp are very useful, they help to strengthen the musculoskeletal system, and also have a beneficial effect on the health of the skin and mucous membranes.

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 in your case, depending on your personal needs. But as for the cooking method, the most useful and safe way for health is grilling, as well as options for dishes where fish is baked and stewed.

In order for the fish to be able to enrich the human body with its useful substances and vitamins, as well as to maintain this process at the proper level, it is necessary to consume it 2-3 times a week, alternating between river and sea fish.

According to the WHO (World Health Organization), eating fish and fish products about 2 times a week reduces the incidence of various diseases. Diseases of the cardiovascular system, cancer, atherosclerosis - and this is not the whole list. Fish is the most unique product that, due to its composition, simply cannot be replaced. Fish contains all vitamins, micro- and macroelements, as well as Omega-3 and Omega-6 acids.Such a content of nutrients and enzymes is no longer found in any food product known to science. Omega acids are the most valuable of all enzymes; their high content in fish helps the human body to equalize the amount of lipid and cholesterol that is dangerous for blood vessels. It is because of this property that nutritionists love fish so much. Cholesterol plaques are the main cause of atherosclerosis and heart attacks in humans. Fish is also the most favorite food of nutritionists, the process of digesting fish takes about two hours, while digesting the same amount of meat will take about five hours. Type of fish. Fish are divided into three types: fatty, medium and skinny. Protein is the main building material in the human body, and in fish the average content of complete and easily digestible protein is 15%, as well as irreplaceable elements necessary for the normal functioning of the body - iodine (for the central nervous system), zinc, phosphorus and fluorine. The statement that beneficial properties are contained only in live fish is erroneous. Fish is an amazing product in this sense, with proper storage, all useful and necessary substances and enzymes are preserved. But fresh river fish can be dangerous to the body. If the fish just caught from the river contains eggs of worms, then the use of such fish can negatively affect health. To avoid trouble, it will be enough to properly heat the product or salt it with a significant amount of salt. It is also a mistake to believe that the higher the price on the price tag in the fish store, the higher the amount of nutrients in this fish. Price and quality. Value for money is not about fish. If we take, for example, cod, in which a sufficiently high content of methionine, can prevent the deposition of fat in organs and normalize fat metabolism. And expensive types of fish, such as salmon, trout, are classified as oily fish. The consumption of such fish is not recommended for obese patients. Useful properties of river fish., And fish with a low fat content (lean - the fat content is no more than 8%) helps people with overweight and atherosclerosis to cope. In order to get all the beneficial properties of fish and not lose anything, you need to cook it properly. The most correct way is to boil the fish; baking or cooking over an open fire is also perfect. If the fish is baked in the oven, then it is necessary to discard the foil, because all the fat will be on the fish. During the frying process, some rules must be followed. The pan, preferably cast iron, should have thick edges. It is better not to cover with a lid when frying in order to avoid the accumulation of excess moisture, otherwise the appearance of the cooked fish will be unappetizing. The fish can be cooked over an open fire or over charcoal. In terms of beneficial enzymes, salting the fish is not the best option. All nutrients remain unchanged, but a high salt content is unacceptable for people with kidney disease, cardiovascular system. Eating smoked fish can negatively affect human health. When smoked, carcinogenic substances appear, which, if used regularly, contribute to the development of cancer. The highest content of such substances is in hot smoked fish. How to choose quality fish? There is a huge amount of fish in stores, but how to correctly determine the quality? A quality fish has red eyes and dark red gills. If there is mucus on the gills, and the eyes are cloudy, this is the first call that the fish is not the first freshness. The mucus on the skin surface should be colorless and free from foreign odors. When pressing on the scales, there should be no dents. At home, the freshness of fish can be determined by putting it in a bucket of water, fresh fish will sink to the bottom, and stale fish will surely float up. For a deeper and more detailed study, a special laboratory and specialists will be required. What is the healthiest river or sea fish? Marine is of course healthier - high content of fatty acids, vitamins and macronutrients. It is better to eat fish of medium or small size, as they do not have time to accumulate harmful substances. Also, proper preparation will help reduce the concentration of harmful substances. The fish was not only used as food. Properties known to us for a long time ... Even ancient healers discovered and actively used the medicinal properties of river fish. Fish glue was used for bleeding, and in some tribes, the liver of fatty fish was used to remove leucorrhoea. Some fish species have antibacterial and antipyretic properties. Time passes, science, thanks to its achievements, has advanced medicine far ahead.

Capelin is the most charming marine life, which contains many useful substances. It tastes great and doesn't take long to cook.

What types of river fish are good for the body

Interestingly, in spring, mackerel fillets are characterized by a low fat content (3%), and by autumn this figure increases to 30%.

Salmon, or Atlantic salmon, spends most of their life in the sea, but they spawn in fresh water. Eggs of fish develop in river pebbles from autumn to May, until hatching begins. After 2 to 5 years of growth and development, the fry become capable of "adult" life, after which they leave the river pebbles and go into the sea.

The best choice for the stronger sex

The beneficial properties of fish are due to the content of nutrients that contribute to:

Mackerel contains magnesium, sodium, fluoride and protein, which are easily absorbed by the body. The systematic use of mackerel increases erectile function, increases the rate of blood circulation in the genitals, and prevents the development of cancer.

Pink salmon contains sodium, zinc, chromium and fat-soluble vitamins that slow down the aging process and strengthen the strength of blood vessels. Pink salmon prevents the occurrence of hypertension, as well as diseases of the cardiovascular system, stroke and heart attack.
