But you can’t always find fish products in supermarkets good quality. 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 one word - any! The main thing is how you cook it. After all, fish fried in oil may be too high in calories. It is better to bake rib steaks in the oven or use a double boiler for preparing fish dishes.

Product health hazards

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

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

The benefits of the fish are directly affected by the method of its culinary preparation. The salty product can be dangerous for people with kidney problems. Hot smoked fish is tasty, but it accumulates carcinogenic substances during such cooking.

Sea 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 good for is its Omega-3 and Omega-6 polyunsaturated fatty acids. These substances are not found in other foods. River fish has fewer amino acids. The meat of sea creatures contains bromine and iodine.

There is molybdenum, cobalt, manganese, zinc, iron, copper, fluorine, sulfur, sodium, magnesium, potassium. Sea fish are not inferior in vitamin content to vegetables and fruits. They contain the entire B line, as well as PP, A, D and H.

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

River fish: pros and cons

Yes, the inhabitants of fresh water bodies are inferior to their sea sisters in the number of amino acids. They do not contain iodine or bromine. But dieters know how fish is beneficial. It won't cause growth extra pounds, it will not cause indigestion or diarrhea. River fish is low in 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, recently caught in a nearby river or lake. And this product - because it is available and available in large quantities - is usually not very expensive. However, there is one thing. Fresh water bodies, especially ponds and lakes, are more polluted by humans. And the environmental situation directly affects the quality of the product.

Product harm: poisonous fish

Here it is necessary to identify several types of dangers to humans. There are poisonous fish such as fugu or brown rocktooth. Only licensed chefs can prepare them: one mistake and the meal 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 healthy fish that have poisonous body parts.

Sep-12-2016

These questions often arise among those who care about their health and are interested in traditional methods treatment, in particular to treatment with food. And this interest is understandable. Maybe in this article, to some extent, you can get an answer to these questions.

What is healthier to eat - meat or fish? Are all fish healthy and in what cases can eating fish harm us? Which fish is better - river or sea? Which types of cooking fish are preferable and which should be avoided? This will be discussed further.

Fish has been one of the most important products in the human diet since its inception. human race. Many types of river and sea fish today overflow the windows of our stores. It is sold fresh and frozen, salted, smoked, dried, various canned goods and even sausage are made from it. What are the health benefits of eating fish?

One of the best sources of animal protein for the human body is fish. Eating fish is much more preferable to us than meat.

Its protein contains all the amino acids we need, and, unlike meat, fish large number such an important amino acid as methionine.

Fish protein is low in connective tissue and fat (only about 30% in the fattest types), so it is digested faster and easier. Fish is digested in the stomach in 1.5–2 hours, and, for example, beef in 5 hours. The percentage of digestibility of fish by our body is 94–98%, while meat is digestible only by 85–89%.

The calorie content of fish is also less than that of meat. In 100 g of beef you can find more than 160 kcal, and in river fish there are no more than 90 of them.

In addition, fish is a very valuable food product also because it contains a fairly large amount of polyunsaturated fatty acids omega-6 and omega-3 and beta-carotene. These substances participate in intercellular processes and are simply irreplaceable for the body.

Scientists have long noticed that in those countries where fish is the main and daily product on the dinner table, people are much less likely to suffer from cardiovascular diseases, they have almost no cardiac arrhythmia, shortness of breath, they are more active and less tired than “meat eaters.” .

It has been proven that if you eat sea fish at least once every 7 days, the risk of a heart attack is reduced by more than 2 times, and a stroke by 22%! The daily consumption of sea fish as food still to a greater extent reduces the likelihood of these diseases!

In addition, regular consumption of fish prevents the occurrence of cancer.

However, this effect is inherent only in fatty sea fish: mackerel, tuna, herring, salmon, sardines and even sprat, and river fish almost does not have it.

Any fish contains many trace elements - magnesium, zinc, potassium, calcium, and especially phosphorus. Sea fish contains a lot of bromine, fluorine and iodine. Fish also contains iron, copper, manganese, sulfur, sodium, selenium and even gold. All types of fish are rich in vitamins B, D, E, and fish liver has a high content of vitamin A.

IN folk medicine fish have long been used as remedy. Fish glue helped with hemorrhages, fish oil healed wounds, the liver of oily fish relieved eyesores, and tench meat was used to treat gout and fever.

Nowadays, fish is used to produce such medicines, like compolon, pancreatin, insulin and many, many others.

The benefits of sea fish

Sea fish is useful:

to reduce excess weight (it is quite low in calories);
for various diseases of the gastrointestinal tract (easily absorbed by the stomach);
for diseases of the thyroid gland (contains a lot of iodine);
has an antitumor effect (due to the high content of vitamins B and E and unsaturated acids);
has an anti-inflammatory effect (again, iodine!);
has a beneficial effect on cardiovascular system, thereby reducing the risk of strokes and heart attacks (potassium, vitamins B, B1, D, unsaturated acids);
improves vision (fish contains a lot of vitamins A and B2);
reduces cholesterol levels in the blood (due to the high content of unsaturated acids omega-6, omega-9, vitamins B3 and B12);
contributes to the normalization of higher nervous activity(contains iodine, calcium, iron, magnesium, B vitamins, omega-3);
increases life expectancy.

The benefits of river fish

River fish is less healthy than sea fish, but still preferable to any meat. Among river fish, pike perch, pike, bream and burbot are considered the most delicious and healthy.

Amount of protein and fat different types river fish varies. Perch, pike perch and pike have only 1% fat, while in bream, carp and catfish its content is 2.5%.

An interesting fact: in terms of the amount of protein it contains, pike perch is ahead of chicken, and carp is superior to beef!

Fresh fish is the healthiest, so try to eat it whenever possible. Frozen fish is no longer so healthy, and smoked fish can actually be harmful.

During the spawning period, the fish is most useful and nutritious, and during the spawning period it is the most depleted.

River fish also contains a lot of highly beneficial vitamins and minerals. Thus, its meat is an excellent source of provitamin A, tocopherol and vitamin D. Thus, its systematic inclusion in the diet has a positive effect on the condition of the skin and hair, making them healthy. With this diet, the skin becomes smooth, acquires a pleasant natural color and a healthy glow. Vitamin D is essential for maintaining normal health skeletal system and teeth, it is thanks to its sufficient intake into the body that normal absorption of calcium occurs. This substance helps to achieve rapid recovery from fractures, as well as prevent their occurrence and the development of osteoporosis.

In addition, river fish meat perfectly supports normal vision.

In addition to vitamins, this product nutrition is an excellent source of a number of mineral elements. It contains a significant amount of calcium, iodine, iron, as well as magnesium, phosphorus, zinc and selenium. All of these elements are extremely important for our body. Thus, magnesium in river fish has a positive effect on the activity of the nervous system, eliminating the aggressive effects of stress. Accordingly, eating fish effectively normalizes night sleep, relieves irritability. Zinc, by the way, will be very useful for males, as it plays an important role in normalizing the activity of the reproductive system.

The daily intake of fish is 150–200 g for an adult.

Fish for pancreatitis

Despite everything useful qualities Fish oil should be excluded from the diet of patients with pancreatitis.

It is worth considering that with pancreatitis, even the healthy fat that fish contains has a negative effect on pancreatic cells, creating an increased load for them. The reason for this is the fact that lipase (an enzyme synthesized in the pancreas) is necessary to break down fat. In the acute phase of the disease, the enzymatic activity of the gland is purposefully suppressed, and during remission this enzyme is produced in insufficient quantities.

If the pancreas is inflamed, only certain varieties of sea and river fish can be included in the diet. The main condition for its choice for pancreatitis is the fat content; it is allowed to consume those varieties whose fat content does not exceed 8%.

Low-fat, in turn, can be divided into skinny and moderate-fat. The introduction of fatty fish dishes into the diet of a patient with pancreatitis is unacceptable in the acute stage and extremely undesirable during the period of remission.

Fish diet

Eating fish is great way lose weight. Nutritionists say that a fish diet fully meets the basic principles of losing weight. The principle of separate nutrition also makes its contribution, that is, there is pure consumption of proteins without mixing them with other elements. The amount of fats and carbohydrates in the diet will be limited, so the fish diet will be moderately fasting. Best period for a fish diet - winter. It is at this time that the body experiences the strongest need for vitamins, which can be replenished (in particular vitamin D, which fish is rich in), while simultaneously gaining a slim figure. You cannot repeat the diet immediately after finishing it; it is recommended to wait 6-8 weeks.

The basis of the diet, of course, will be fish. Which one should you choose? It is best to give preference to fresh, but it is not forbidden to sometimes cook frozen and include canned fish in the menu. The best dietary fish varieties are pike perch, hake, tuna, flounder, cod, and navaga. Pink salmon and salmon are higher-calorie varieties, but if desired, they can also be included in the menu, provided they are cooked without oil. At all best ways cooking is steaming, stewing or grilling. Use fried fish It's better to keep it to a minimum. And with any cooking method you should try to use less fat. It is also allowed to eat seafood (in the absence of allergies) - squid, mussels, shrimp; fermented milk products, fruits (except bananas) and eggs.

Harm to fish

Like any other food product, fish can, along with its benefits, also cause significant harm to our health.

Some 70–100 years ago, the environmental situation on our planet was completely different. And over the past decades, people have managed to spoil the air, water, and land so much that many food products, unfortunately, have moved from the category of useful to the category of harmful to health. Alas, this circumstance can fully be attributed to fish. Therefore, when eating a particular type of fish, it is first of all advisable to know where it was caught. Fish from ecologically polluted regions is also contaminated with various kinds of toxins and wastes, which easily enter the body of the person who eats such fish. It would never occur to us to drink water from such a dirty reservoir, but we often do not think about the harm that fish caught in it can cause to our body!

According to statistics from the US Department of Health, saltwater fish and seafood are the most common cause of all food poisoning and rank first on this sad list every year!

Such poisoning, in addition to feeling unwell, diarrhea, vomiting and headaches, can lead to disruption of the human kidneys and nervous system, and in severe cases, to death.

We all know what a terrible impression our rivers and lakes sometimes make on us. Oceans and seas, unfortunately, are no exception to this rule. During its life, sea fish, like a sponge, accumulates salts of heavy metals, lead, mercury, arsenic, radioactive cesium, and other chemical elements that are very harmful to health.

Fish grown in special artificial reservoirs, despite the fact that they live in clean water, can also pose a threat to our health. This is due to the fact that such fish, as a rule, are treated with food made from waste from the same fish production, in which there are plenty of harmful substances.

The larger and older the fish, the more harmful substances it contains, so small fish are more preferable for our diet than large species of fish. The most harmful meat is considered to be shark meat, swordfish, king mackerel, giant mackerel, lofolatilus and some types of tuna.

The least mercury and its compounds are found in salmon, pollock, whitefish, catfish, light tuna (this is the type used in the preparation of canned fish) and shrimp.

Mercury and its compounds are the strongest poison for the human body, and in addition, they have the ability to accumulate in it and cause incurable diseases, including cancer.

Symptoms of mercury poisoning can include depression, fatigue, inability to concentrate, headaches and hair loss.

Few people know that fish is the only source of mercury entering our body and there is no mercury in other food products!

Tuna may contain a special, potent fish poison called ciguatera, which can cause severe poisoning.

In many European countries, tuna and canned tuna are prohibited for consumption during pregnancy at the official state level!

During this period, they are also considered hazardous to health. expectant mother pink salmon, nelma, beluga, chinook salmon, navaga, pollock and hake, which is so common in our country.

Smoked fish also causes a lot of harm to our body. Carcinogens that form in it during the smoking process provoke the development of various types of cancer. The greatest danger in this regard is fish prepared by hot smoking, especially those made not in industrial conditions, but in an artisanal way over a fire.

Cold smoked fish is less dangerous, although it is not recommended to eat it more than once every 10 days, but there is no need to talk about its any benefits at all.

Today, very often, unscrupulous manufacturers generally replace the process of smoking fish by soaking it in so-called liquid smoke, which in essence is nothing more than tar. And although such fish in its appearance and taste are practically no different from smoked fish, the harm from eating it increases tenfold!

Fish is a product that brings enormous benefits to our health. It is not for nothing that all nutritionists in the world agree that without fish, the diet will not be sufficiently complete and healthy, and this product should definitely be consumed at least once a week.

Seafood has richest vitamin and mineral composition In addition, they are record holders for the content of some elements necessary for humans (for example, phosphorus and numerous fatty acids). And, of course, cooked according to the right recipe fish is a real delicacy for gourmets.

What else is this product good for our health, what is its potential harm and what should we remember when using it?

Nutritional value and calorie content of fish

Nutrient content and energy value, like the beneficial properties of fish, may vary. It depends on the species and habitat. Fat content can vary from 2% to 15% or more. Calorie content also changes. But no matter how fatty the fish is, meat is many times higher in fat content in terms of these indicators, as well as in terms of harm to human health. Therefore, marine and freshwater inhabitants are considered a dietary product with significant beneficial properties.

The benefits and harms of fish for the body and calorie content vary depending on the technological and culinary processing applied to the product. Salting, drying, and smoking significantly affect these indicators. Fried fish has the highest calorie content, which is harmful to the body and neutralizes most of the beneficial properties of the original product. Therefore, it is recommended to boil and consume it without adding additional fat. This also applies to vegetable oils, an excess amount of which can cause significant harm to the figure.

The nutritional composition of fish is richer and more varied than that of meat. Those present in it chemical compounds have beneficial properties and therapeutic effects. Everyone is well aware of the benefits of fish oil, cod liver, etc.

The benefits of fish for the human body

With frequent consumption, the medicinal properties of fish become noticeable. It is quickly digested and does not linger inside the gastrointestinal tract, unlike meat and poultry. This is explained by the difference in the structure of muscle fibers, which do not have a dense, hard-to-digest shell and, thanks to this, begin to be absorbed first. This explains the beneficial dietary properties of the product.

In oily fish that live in northern waters, contain Omega-3 PUFAs, the beneficial properties of which help avoid the development of cardiovascular pathologies, improve peripheral circulation, and reduce the risk of thrombosis. All this helps prevent early death from heart diseases. At the same time, you should know that in red fish grown under artificial conditions there is almost no Omega-3, and therefore there are fewer beneficial properties.

Marine species should be eaten to improve thyroid function. They contain a high concentration of iodine, the beneficial properties of which have a huge impact on humans. This element is necessary for the production of thyroid hormones. The most noticeable amount of iodine is found in tuna and pink salmon, the beneficial properties of which are well known to everyone.

Fish oil will have beneficial influence on visual function - thanks to the properties of PUFAs and vitamin A. These chemical compounds strengthen vision and prevent the development of night blindness. Cholesterol is present in both river and sea species. However, there is very little of it here and, unlike meat, it does not cause any harm. In addition, marine life helps eliminate excess cholesterol due to the presence of beneficial properties of PUFAs. Unfortunately, river fish does not reduce the harm of cholesterol in the body.

What are the benefits of fish for children?

Fish dishes for children are an ideal product, rich in substances with beneficial properties: easily digestible proteins necessary during the period of intensive growth, vitamin D, calcium, phosphorus. They help develop the musculoskeletal system, provide an opportunity to develop mentally, physically, and be highly active.

What kind of fish can you give to your child?

The child’s diet must contain the beneficial properties of fish dishes. They provide vital nutrients. But not every variety can be given to children because possible harm for a not fully formed organism that does not function as efficiently as in adults.

Children can be fed low-fat or semi-fat sea varieties, the beneficial properties of which are suitable for early age. The former include hake, pike perch, flounder, cod, river cod, navaga, and the latter include sea bass and crucian carp, herring, trout, and others. Herring, mackerel, salmon are not suitable for baby food and can be harmful. The health benefits of river fish for children are significantly less.

Attention! Fish dishes can cause a hypersensitivity reaction, as they are a strong allergen. Therefore, to prevent such harm, it would be useful to give them to your baby, starting with small doses.

Fish for weight loss

Included low calorie diets It is often recommended to introduce fish dishes instead of meat. They contain the beneficial properties necessary for this: they are easier to digest, have a rich vitamin and mineral composition, which will be useful under strict dietary restrictions. However, the properties of fatty types are not suitable for these purposes due to their high calorie content: they can rather harm the figure than save it from extra pounds.

But even the unleavened varieties that are most beneficial in terms of dietary properties should not be fried or smoked. Additional cooking gives the dishes not benefits, but extra calories and salt. You should not season finished carcasses with a large amount of oil, even if it is vegetable. The benefits of steamed fish, boiled and baked dishes are well known.

Which fish is healthier: river or sea?

Each type has its own characteristics chemical composition. The benefits of river fish for the human body are high in protein and low in calories. But it is still better to give preference to marine species, since they are cleaner, contain more rare and essential nutrients, and have better taste and beneficial properties. Thanks to the presence of fatty acids, vision, heart, and nervous system function well. Lovers of fish delicacies have more high intelligence, performance, tumor diseases are much less common, and they live longer.

Attention! Marine species have a high iodine content, which is very rarely found in food. Without its beneficial properties, it is impossible for basic life processes to occur, which poses irreparable harm to the body.

Is dried and dried fish healthy?

Benefit dried fish for health is an increased concentration of nutrients. There are more beneficial properties of Omega acids, vitamins, and minerals. But dried fish also has a high concentration of salt, which can provoke the development of diseases of the joints, heart, blood vessels, and complicate the functioning of the kidneys. It is not recommended to buy homemade goods, somewhere on the market, from hand. The benefits and harms of dried fish depend on the method of its processing. Improper salting or drying does not kill helminth larvae, and they enter the human body.

Greatest benefit dried fish manifests itself if the technological processing of the product took place in a factory environment. It includes careful selection of raw materials and compliance with all production nuances. In the case of goods purchased second-hand, this cannot be said: the fish may be caught in a polluted water body or cooked with violations during the processing process. Then the benefits of dried fish for humans become questionable.

Attention! A low-quality product with insufficient or incorrect technological processing can cause infection with helminth larvae, poisoning and other negative consequences.

The benefits and harms of smoked fish

Hot smoked fish does not bring any particular benefit. The properties of such processing technology to release harmful carcinogenic substances eliminate all the beneficial qualities of the product. The highest concentration of such compounds is present in hot smoked fish. At high temperatures Carcinogenic substances accumulate faster on the skin of the fish and penetrate deeper into the fish more intensively.

The most dangerous are the thin-skinned varieties: herring, mackerel, herring, capelin, cooked over a fire. Hot smoked fish produced in a factory will have less harm and dangerous properties. Thick-skinned varieties of cold-smoked fish (carp, trout, bream) are considered the most useful in this regard.

So, the benefits and harms of smoked fish depend on its type and method of technological processing: hot or cold.

Which fish is the healthiest for humans?

It is believed that fresh fish has more beneficial properties than frozen fish. But this is not always the case. Indeed, some part of the substances is destroyed by exposure low temperatures. But fresh fish also has vulnerabilities. It quickly deteriorates, which negatively affects its quality and makes it capable of causing harm to the consumer.

Therefore, it is often better to purchase frozen fish, which have been frozen immediately after catching. The overall benefit from such a product may be higher.

One interesting misconception is common among people. For some reason, red fish is given the most beneficial properties. But as chemical analysis of the composition of both species shows, this is far from true. It is enough to compare some characteristics:

Substances

Necessary for metabolism and increasing muscle mass.
Phosphorus,% of daily value Strengthens teeth and bone tissue, helps the kidneys and nervous system.
Calcium,% Strengthens the bone apparatus, the central nervous system, participates in the work of the adrenal glands, thyroid, pancreas, gonads, pituitary gland.

The greatest benefit of sea fish for the daily diet, as can be seen from the table, lies in the white varieties. In addition, they are not only healthier, but also much cheaper than red ones.

Harm to fish and contraindications for consumption

The most toxic are the predatory species (tuna, navaga, pollock, nelma, hake, pink salmon, beluga, chinook salmon), since the food chain is interrupted on them. Predators can accumulate large amounts of mercury. And the older the individual, the more toxins it contains.

Ideally, in the absence of an allergy to the product, fish will be useful in the diet of every person. It is better to buy live or at least fresh fish. If this is not possible, it is necessary to choose the right frozen fish. However, the degree of its freshness is difficult to determine. Unscrupulous traders often take advantage of this and offer low quality products. What you need to know:

It is not advisable to purchase fish without a head. It is from this part of the body that it begins to deteriorate, and poor quality product goes to freeze.
Particular attention should be paid to the eyes and gills. Based on their condition, you can easily determine the quality of the product: whether it was frozen fresh. The eyes should be light, bulging, not sunken, gill covers and fins should be tightly pressed, not protruding.
The shape of a freshly frozen carcass will be without damage. If it has lost its appearance and correct outlines, it means that it has been defrosted more than once.
The color of a quality product is uniform, the scales have shine or silver. Areas that stand out against the general background - whitish spots, a yellowish tint on the belly - indicate a stale product.
The weight of the fish should not be small. If the carcass is unnaturally light, it means that it has been stored in the freezer for a long time and has dried out: its meat will break off easily and have a bland taste.

When choosing fresh fish, you need to pay attention to the following features:

the smell should be sea, salt, without foreign inclusions;
when pressed with a finger, the fish body should spring back, and the mark should disappear almost immediately;
The gills should be saturated with blood and have a dark color.
