Sea fish: benefits and positive effects on the body. In what cases is sea fish harmful to health?


What kind of fish, where is it found, description

This grass carp feeds exclusively on plant foods. However, her appetite is truly limitless. In a day, a fish can eat so much algae that its volume will be greater than its own weight. For this reason, grass carp is sometimes called a “water cow” and is used to clean water bodies.

On a note! Cupid loves fresh cucumbers and young corn, and will not refuse beet or cabbage leaves. In search of food, it sometimes jumps out of the water to grab emergent plants. Experienced fishermen use this feature to lure fish to tasty bait.

Every year the fish gains ten centimeters in height. Of course, this also affects the weight of the fish. An adult can weigh more than forty kilograms.

The elongated body of this fish resembles a torpedo in appearance. Its body is slightly flattened on the sides. The belly is yellow or cream in color. Compared to the body, the grass carp's head is quite small.

Grass carp are mainly active during the day. Sometimes it can be found in shallow water. There the fish loves to bask in the sun's rays. And he spends the winter in pits made of silt and sand. Grass carp is very hardy and can thrive even in salt water.

By the age of ten, the fish reaches sexual maturity. The homeland of grass carp is China. The “water cow” received its name thanks to the Amur River, where it is most often found.

The fish is successfully bred in farms, and in natural conditions it lives in the backwaters of large rivers in Russia - the Yenisei, Volga and Don.

Not all fish are healthy. There is one from which it is better to stay away, and if you allow yourself to eat a piece, then it is small and only occasionally. 1. Imported catfish, pangagius, Taiwanese catfish, tilapia. The vast majority of imported farmed fish (90%) comes from Vietnam, where the use of antibiotics, which are banned in many countries, is widely practiced in its cultivation. Catfish living in the wild and caught in our country can be considered safe. 2. Imported (Atlantic) cod. Its consumption is not so much a challenge to health as an act of vandalism, since due to uncontrolled fishing and other unfavorable conditions, Atlantic cod is almost on the verge of extinction and being included in the Red Book. But if you can’t imagine life without cod, then you can safely enjoy the Pacific species, of which there are still many.

3. Eel. Eel is a delicious fish that is widely used in making sushi. And it was included in the list of harmful fish due to the fact that it is extremely contaminated with mercury and PCBs (polychlorinated biphenyls), which not only simply kill the liver, but also accumulate in the body.

Eel fish farms tend to be highly contaminated with waste and suffer from overproduction and overcrowding. A safe alternative to eel is Atlantic or Pacific squid.

4. Shrimp . They top the list of unhealthy fish due to their high levels of cholesterol and pollutants, and are also difficult to avoid since over 90% of shrimp are imported. Imported farmed shrimp are imported along with a “charming” set of pollutants: these are antibiotics, chemicals that get into the water after cleaning cages, and even garbage such as mouse and rat hairs, droppings, insect remains, etc. And this is not to mention various a type of bacteria such as E. coli, which is often found in shrimp.

5. Atlantic flounder . This group of fish includes turbot, salt, rhombus, glossa, galkan, limanda, sole and halibut , caught in the Atlantic. They have been blacklisted due to high levels of pollution, as well as overfishing that dates back to the 1800s. Ecologists estimate that the Atlantic flounder population is only 1% of what is acceptable for long-term fishing. A safe alternative is Pacific halibut.

6. Atlantic salmon, salmon, pink salmon. Fishing for wild salmon is prohibited due to alarmingly low populations. Which, oddly enough, is even more threatened by farmed salmon farming. In farm settings, thousands of fish are crammed into cramped cages, infecting each other with diseases and parasites that require the use of antibiotics and pesticides. Often individuals will "escape" and infect wild species, further reducing the wild population. A safe alternative is Pacific salmon.

7. Shark. Eating shark meat is undesirable for a number of reasons. Firstly, the meat of these predators contains too much mercury. Secondly, fishing for this fish disrupts the ocean ecosystem. A decrease in the number of sharks leads to the “clogging” of the oceans with species that sharks prey on: jellyfish and stingrays. And stingrays, in turn, destroy the population of small commercial fish. Meanwhile, mackerel or halibut can serve as an excellent replacement for shark.

8. Atlantic tuna. Recent analyzes show that Atlantic tuna contains record levels of mercury compared to other fish species and even other types of tuna. In addition, Atlantic tuna is also in danger of extinction. If you are a tuna lover, then buy Pacific species and choose young, medium-sized specimens that have not accumulated a lot of mercury.

The waters of our planet have become so polluted that it is quite difficult to determine which fish are safe and which are not. The healthfulness of fish depends on its habitat, whether natural or farmed, the quality of the food, the level of contaminants such as mercury, and many other factors.

Lists of “good” fish may change from year to year for a number of environmental and production reasons, but it is better to completely avoid the above-mentioned types of fish and seafood. Moreover, only a small amount of fish and seafood is inspected before it reaches the counter. It is especially not recommended for pregnant women and children to consume such fish. Info.myjane.ru

BUT! :

Do you think fish is a healthy food? Think again. Fish live in water so polluted that you wouldn't even think of drinking it.

And yet you are ingesting this toxic cocktail of bacteria, toxins, heavy metals, etc. This happens every time you eat fish.

Recently, the waters of the world's oceans have been polluted and this process, alas, also affects its inhabitants. Just as they are beneficial, fish begin to accumulate harmful substances - salts of heavy metals, mercury. Consumption of such fish has a catastrophic effect on health, especially for pregnant women and children, since mercury has a bad effect on the cells of the growing brain. If you are expecting, do not eat shark, king mackerel, Lopholatilus, swordfish (Xiphias gladius) or any type of tuna (Albacore tuna). According to scientific research, these fish are most susceptible to mercury poisoning.

Due to industrial pollution, fish accumulate mercury in their meat. Fish absorb mercury and it is deposited in their tissues. If you eat fish, your body will absorb mercury from the fish meat, and the accumulation of this substance can lead to serious health problems. It should be noted that fish is the only way a person can come into contact with this poison. Eating fish and other marine animals is the only way humans come into contact with mercury. New England Journal of Medicine, 2003

The world's oceans are polluted by chemical waste that can accumulate in fish. The most dangerous in this regard are such exotic fish species as shark and swordfish, which have no scales. In addition, the larger the fish, the more toxins it may contain. So it makes sense to give preference to smaller specimens. But even small fish need to have their heads cut off and the fish thoroughly cleaned of scales.

Seafood is the No. 1 cause of poisoning in the United States. Seafood poisoning can lead to very poor health, damage to the kidneys and nervous system, and even death.

Mercury is not the only dangerous element in fish.

People who eat fish also receive polychlorinated biphenyls. Big fish eat small fish, so the concentration of polychlorinated biphenyls in the bodies of large fish becomes higher. People exposed to polychlorinated biphenyls through fish consumption experience impaired brain function, reproductive dysfunction, and an increased risk of cancer.

Dr. SusanL. Susan L. Schantz of the University of Illinois College of Veterinary Medicine has studied people who eat fish since 1992 and found that those who eat 24 or more pounds of fish in a year have memory problems. On average, people around the world eat 40 pounds of fish per year.) She found that people who eat fish have high levels of polychlorinated biphenyls in their blood, and because of this, they have trouble remembering information that they received only 30 minutes ago.

“It has been established that adults are less susceptible to the effects of polychlorinated biphenyls than the developing fetus. This may not be the case." In her study, many people who ate fish had high levels of lead, mercury, and DDE (formed by the breakdown of DDT) in their blood. Even low concentrations of lead can cause developmental defects and mental retardation in children. Higher concentrations can lead to epilepsy and even death.

How to choose and how to store

The product can be found both in a regular store and at the grocery market. But choosing a quality product is quite difficult. Usually the carcasses of adult, medium-sized fish are chosen. Then the meat will be better separated from the bones.

You need to smell it before buying. The carcass should not smell like mud. If the scales are dull, the product has probably been stored for a long time. The fins of grass carp must be elastic.

Grass carp must be stored correctly. Fish fillets cannot be stored for a long time. The semi-finished product can be left in the refrigerator, but for no more than two days. Once frozen, the product can be stored in the freezer for up to two months.

However, before cooking, it is completely defrosted. This way you can evaluate the appearance of the fish and its condition. If there is a suspicion that the meat is spoiled, it is better to dispose of it to avoid poisoning. Repeated freezing of grass carp is unacceptable.
