Sep-12-2016

What kind of fish are there, the benefits and harms of fish for the human body, and does it have any medicinal properties? These questions often arise among those who care about their health and show interest in traditional methods of treatment, in particular in 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? What types culinary processing Which 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 contains a large amount of 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 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 the 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%.

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.

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 use 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 receiving 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 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, 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 environmentally 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 meat of shark, swordfish, king mackerel, giant mackerel, lofolatilus and some types of tuna is considered to be the most harmful.

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 a fish in its own way appearance and its taste is practically no different from smoked fish, the harm from eating it increases tenfold!

Each of these products has its own effect on the human body, and in addition to satiation, performs its function even at the cellular level.
