USEFUL PROPERTIES OF COD LIVER. CANNED CONSERVATIONS

Cod liver. Canned food rich in vitamins and minerals such as: vitamin A - 488.9%, vitamin B2 - 22.8%, vitamin B6 - 11.5%, vitamin B9 - 27.5%, vitamin D - 1000%, vitamin E - 58 .7%, vitamin PP - 13.5%, magnesium - 12.5%, phosphorus - 28.8%, chlorine - 44.1%, cobalt - 650%, copper - 1250%, molybdenum - 20%

What are the benefits of Cod Liver? Canned food

• Vitamin A responsible for normal development, reproductive function, skin and eye health, and maintaining immunity.
• Vitamin B2 participates in redox reactions, helps to increase the color sensitivity of the visual analyzer and dark adaptation. Insufficient intake of vitamin B2 is accompanied by impaired condition of the skin, mucous membranes, and impaired light and twilight vision.
• Vitamin B6 participates in maintaining the immune response, processes of inhibition and excitation in the central nervous system, in the transformation of amino acids, the metabolism of tryptophan, lipids and nucleic acids, promotes the normal formation of red blood cells, maintaining normal levels of homocysteine ​​in the blood. Insufficient intake of vitamin B6 is accompanied by decreased appetite, impaired skin condition, and the development of homocysteinemia and anemia.
• Vitamin B9 as a coenzyme they participate in the metabolism of nucleic acids and amino acids. Folate deficiency leads to disruption of the synthesis of nucleic acids and proteins, resulting in inhibition of cell growth and division, especially in rapidly proliferating tissues: bone marrow, intestinal epithelium, etc. Insufficient folate intake during pregnancy is one of the causes of prematurity, malnutrition, and congenital deformities and child development disorders. A strong relationship has been shown between folate and homocysteine ​​levels and the risk of cardiovascular disease.
• Vitamin D maintains homeostasis of calcium and phosphorus, carries out the processes of mineralization of bone tissue. A lack of vitamin D leads to impaired metabolism of calcium and phosphorus in the bones, increased demineralization of bone tissue, which leads to an increased risk of developing osteoporosis.
• Vitamin E has antioxidant properties, is necessary for the functioning of the gonads and heart muscle, and is a universal stabilizer of cell membranes. With vitamin E deficiency, hemolysis of erythrocytes and neurological disorders are observed.
• Vitamin PP participates in redox reactions of energy metabolism. Insufficient vitamin intake is accompanied by disruption of the normal condition of the skin, gastrointestinal tract and nervous system.
• Magnesium participates in energy metabolism, synthesis of proteins, nucleic acids, has a stabilizing effect on membranes, and is necessary to maintain homeostasis of calcium, potassium and sodium. A lack of magnesium leads to hypomagnesemia, an increased risk of developing hypertension and heart disease.
• Phosphorus takes part in many physiological processes, including energy metabolism, regulates acid-base balance, is part of phospholipids, nucleotides and nucleic acids, and is necessary for the mineralization of bones and teeth. Deficiency leads to anorexia, anemia, and rickets.
• Chlorine necessary for the formation and secretion of hydrochloric acid in the body.
• Cobalt is part of vitamin B12. Activates enzymes of fatty acid metabolism and folic acid metabolism.
• Copper is part of enzymes that have redox activity and are involved in iron metabolism, stimulates the absorption of proteins and carbohydrates. Participates in the processes of providing oxygen to the tissues of the human body. Deficiency is manifested by disturbances in the formation of the cardiovascular system and skeleton, and the development of connective tissue dysplasia.
• Molybdenum is a cofactor for many enzymes that ensure the metabolism of sulfur-containing amino acids, purines and pyrimidines.

You can see a complete directory of the most useful products in the appendix - a set of properties of a food product, the presence of which satisfies a person’s physiological needs for the necessary substances and energy.

Vitamins, organic substances required in small quantities in the diet of both humans and most vertebrates. Vitamin synthesis is usually carried out by plants, not animals. A person's daily requirement for vitamins is only a few milligrams or micrograms. Unlike inorganic substances, vitamins are destroyed by strong heat. Many vitamins are unstable and are “lost” during cooking or food processing.

Cod is a marine fish of the cod family. It has a greenish-brown color with brown spots and a white belly.

The size of cod depends on its age: the length reaches 1.8 - 2 meters, while the weight of the fish caught ranges from 4 - 12 kilograms.
This fish has a barbel on the chin, three dorsal and two pelvic fins without spiny rays, movable premaxillary and maxillary bones. Its scales are cycloid and its gills are comb-like.

In terms of the structure of the fins, representatives of the cod-like family are similar to the Cyprinidae, and in the position of the ventral fins, they are similar to the Perciformes.

Historical information

Cod has played an important role in the history of Europe and America for more than a thousand years. The Vikings who lived on the Lofoten Islands ate dried fish. Immediately after the catch, it was hung in an open, well-ventilated area; after three months, the carcasses were beaten until the meat became soft and edible. Such nutritious food was stored for a long time, which was ideal for a wandering tribe.

Fish then gained popularity in Europe for religious reasons: unlike meat, it could be eaten during Lent.

Between 1958 and 1976, a diplomatic conflict arose over cod. The controversy stemmed from the first state's imposition of a 200-mile economic zone around the island, which prohibited fishing in Icelandic waters where British fishermen were casting their nets.

Interestingly, the maximum weight of the largest cod caught in history was 96 kilograms.

Characteristic

The fish's habitat covers the Atlantic Ocean (Baltic, White Sea, Arctic cod). In the east of the Atlantic it is distributed from Spitsbergen and the Barents Sea to the Bay of Biscay, in the west - from Greenland to Cape Hatteras. In particular, it lives in the Norwegian Sea, the Pacific Ocean, and off the coast of Iceland. Interestingly, only two types of fish are most often found under the trade name cod - Pacific and Atlantic. Baltic, White Sea, and Greenlandic ones are in less demand.

Cod can withstand low temperatures (from minus 1 degree Celsius and below). Her life expectancy reaches 25 years.

The young individual feeds on mollusks, small crustaceans. At the same time, by the age of three she becomes a real predator and begins to eat other fish: capelin, pollock, herring, and her own young. To catch cod, they use fixed and purse seines, snurrevods, bottom and pelagic trawls, and longlines.

This is a prolific fish that begins to lay offspring in March-April, making long 1,500-kilometer migrations to spawning grounds. Cod spawn in the water column; their numbers can reach up to 2 million in a few weeks.

In 1992, the Canadian government imposed a moratorium on fishing due to a sharp decline in the number of individuals and the threat of complete extinction of the species. This is the most important commercial fish, which is a raw material for the production of canned food and a source of valuable fish oil.

Large exporters of cod: Canada, Denmark, Great Britain, Norway, Russia, Iceland.

With minimal culinary effort, cod can be made into a dish with a puree-like consistency, which is especially important for a diet for pancreatitis, which involves grinding all food products in order to spare the digestive organs.

Fish is allowed to be consumed during the period of remission and exacerbation of the disease from the second week of the attack. It is boiled, steamed, served in the form of meatballs, cutlets, soufflés, quenelles, and meatballs. In addition to dishes prepared from minced cod, during the period of remission it is allowed to eat whole fish (baked, stewed, steamed). It makes nutritious casseroles and pies that will help diversify the patient’s diet.

Fish dumplings are recommended to be served with vegetable and cereal side dishes, vegetarian soups. In case of chronic pancreatitis, animal meat is replaced with cod, which is allowed to be consumed no more than 3 times a week. At the same time, the following fish dishes are prohibited: canned food, liver, aspic and broths that stimulate gastric and pancreatic secretion. In addition, avoid taking dried, smoked, or salted cod.

Remember, the healthiest fish is fresh. It should have a strong, elastic surface, be moderately shiny, and have a marine scent. The presence of yellowish stains on the carcass, damage, and a foul odor indicate long-term storage of the product on store shelves, which has been re-frozen. Avoid eating such fish.

The maximum daily portion of cod for a patient with pancreatitis is 200 grams.

Before cooking, cut off the head, tail, and fins of the fish, gut it and wash it. If necessary, cut into pieces and rinse again under water. When purchasing frozen cod, be sure to defrost the carcass naturally before cooking in the refrigerator. When using a microwave oven or hot water, the fish will lose its taste and consistency.

You can cook the cod whole or in pieces (in portions). However, the finer the fish is cut, the less nutrients it will retain after heat treatment. Cod is cooked in a regular saucepan, double boiler, slow cooker, or pressure cooker.

1. You can put cod in both cold and hot water. In the first case, there is a guarantee that the tough fish meat will be cooked evenly.
2. When placing cod in a regular pan, the water should completely cover its surface.
3. Once defrosted, meat cannot be re-frozen.
4. You can cook fish under a closed or open lid.
5. To enhance the taste of cod, add cucumber pickle, tomato paste, citric acid, salt, carrots, onions, peppers or spices.
6. The fish is cooked exclusively in gutted form.
7. Throughout the entire period of cooking cod, constantly control the heat: at first it should be high, when the water boils, reduce it to medium level, at the final stage reduce it so that it is weak.
8. To preserve the structure of the fish, add 15 milliliters of vegetable oil to boiling water.
9. If you do not have suitable kitchen equipment, you can cook the cod in a deep frying pan, adding water periodically. In this case, the process of preparing sea fish will be no different from the traditional method.

The duration of cooking cod depends on the size of the carcass (cut) and averages 15 minutes. Small pieces will be ready in 5 minutes. The fastest way to cook fish is in a pressure cooker. And the cooking time in a double boiler or multicooker will not differ in any way from heat treatment in a regular saucepan. The readiness of cod can be checked based on two factors: the ease of separating the fillet from the skin and bones, and the degree of meatiness of the meat.

Remember, regardless of the serving size, fish boiled for a baby is cooked for at least 20 minutes, then crushed until creamy and carefully checked for the presence of cartilage and bones.

Conclusion

Cod is a meaty fish with dense flesh and a light amount of bones. It contains a unique set of nutrients that, according to American clinical studies, improve the functioning of the nervous system, help metabolism, strengthen the immune system, lower blood pressure, and reduce the formation of blood clots in the arteries.

Nutritionists recommend eating fish dishes twice a week. If these proportions are observed, the risk of stroke is reduced by 2 times. However, if you increase the frequency of consumption to double the dose per day, the risk of cerebral hemorrhage increases by the same amount.

To prevent the development of Alzheimer's disease, osteoporosis, oncology, rickets, and vitamin deficiency, it is recommended to consume cod oil.
