Magnesium can normalize blood pressure. Iron and manganese cleanse the blood of harmful cholesterol and saturate it with oxygen, which prevents oxygen starvation not only of internal organs, but also of the brain.

Cod liver contains a solid supply of vitamin D, potassium and calcium. These substances are necessary to strengthen the bone tissue of the musculoskeletal system.

What are the benefits of Cod Liver? Canned food

• Vitamin A
  is responsible for normal development, reproductive function, skin and eye health, and maintaining immunity.
• Vitamin B2
  is involved 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
  is involved 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, and 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 is involved 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 calcium and phosphorus homeostasis and carries out the processes of bone tissue mineralization. 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
  is involved 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
  is involved in energy metabolism, the synthesis of proteins, nucleic acids, has a stabilizing effect on membranes, and is necessary to maintain the 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
  is 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 the metabolism of iron, 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.

How to choose cod liver

Cod liver is a highly perishable product. Therefore, it can be found fresh only in places where fish are caught. It is mainly bought in the form of canned food. In order to fully enjoy the taste of a seafood product and get maximum benefits, you should choose it correctly, since the benefits and harm to the body will depend on this.

To choose the right cod liver, it is important to focus on the following points:

1. Appearance of the packaging.
   It is prohibited to purchase canned food if the metal can is damaged. When dents occur, the internal coating is damaged and the product begins to come into contact with iron and oxidize. Liver in bloated packages is also dangerous. This indicates that it is spoiled and harmful bacteria are multiplying inside.
2. Place of manufacture.
   It is better to give preference to canned goods made in coastal regions, near the place where cod is caught. A high percentage is that the raw materials were not frozen before production. The product made from fresh liver is tender and juicy. On such canned food, manufacturers indicate the highest grade.
