Walnut rich in vitamins and minerals such as: vitamin B1 – 22,7%, vitamin B5 – 11,4%, vitamin B6 – 26,9%, vitamin B9 – 24,5%, potassium – 17,6%, magnesium – 39,5 , 43,3%, phosphorus – 16,2%, iron – 170,7%, manganese – 158,6%, copper – 25,8%, zinc – XNUMX%
  • Vitamin B1 is part of the most important enzymes of carbohydrate and energy metabolism, which provide the body with energy and plastic substances, as well as the metabolism of branched-chain amino acids. Lack of this vitamin leads to serious disorders of the nervous, digestive and cardiovascular systems.
  • Vitamin B5 participates in protein, fat, carbohydrate metabolism, cholesterol metabolism, the synthesis of a number of hormones, hemoglobin, promotes the absorption of amino acids and sugars in the intestine, supports the function of the adrenal cortex. Lack of pantothenic acid can lead to damage to the skin and mucous membranes.
  • Vitamin B6 participates in the maintenance of the immune response, inhibition and excitation processes in the central nervous system, in the conversion of amino acids, in the metabolism of tryptophan, lipids and nucleic acids, contributes to the normal formation of erythrocytes, maintenance of the normal level of homocysteine ​​in the blood. Insufficient intake of vitamin B6 is accompanied by a decrease in appetite, a violation of the condition of the skin, the development of homocysteinemia, anemia.
  • Vitamin B6 as a coenzyme, they participate in the metabolism of nucleic acids and amino acids. Folate deficiency leads to impaired synthesis of nucleic acids and protein, which results in inhibition of cell growth and division, especially in rapidly proliferating tissues: bone marrow, intestinal epithelium, etc. Insufficient consumption of folate during pregnancy is one of the causes of prematurity, malnutrition, congenital malformations and developmental disorders of the child. A strong association has been shown between folate and homocysteine ​​levels and the risk of cardiovascular disease.
  • potassium is the main intracellular ion that takes part in the regulation of water, acid and electrolyte balance, participates in the processes of nerve impulses, pressure regulation.
  • Magnesium participates in energy metabolism, synthesis of proteins, nucleic acids, has a stabilizing effect on membranes, is necessary to maintain homeostasis of calcium, potassium and sodium. Lack of magnesium leads to hypomagnesemia, an increased risk of developing hypertension, heart disease.
  • Phosphorus takes part in many physiological processes, including energy metabolism, regulates acid-base balance, is a part of phospholipids, nucleotides and nucleic acids, is necessary for the mineralization of bones and teeth. Deficiency leads to anorexia, anemia, rickets.
  • Iron is a part of proteins of various functions, including enzymes. Participates in the transport of electrons, oxygen, ensures the course of redox reactions and activation of peroxidation. Insufficient consumption leads to hypochromic anemia, myoglobin-deficient atony of skeletal muscles, increased fatigue, myocardiopathy, atrophic gastritis.
  • Manganese participates in the formation of bone and connective tissue, is part of the enzymes involved in the metabolism of amino acids, carbohydrates, catecholamines; essential for the synthesis of cholesterol and nucleotides. Insufficient consumption is accompanied by a slowdown in growth, disorders in the reproductive system, increased fragility of bone tissue, disorders of carbohydrate and lipid metabolism.
  • Copper is a part of enzymes with redox activity and involved in iron metabolism, stimulates the absorption of proteins and carbohydrates. Participates in the processes of providing the tissues of the human body with oxygen. The deficiency is manifested by disorders in the formation of the cardiovascular system and skeleton, the development of connective tissue dysplasia.
  • Zinc is a part of more than 300 enzymes, participates in the processes of synthesis and decomposition of carbohydrates, proteins, fats, nucleic acids and in the regulation of the expression of a number of genes. Insufficient consumption leads to anemia, secondary immunodeficiency, liver cirrhosis, sexual dysfunction, and fetal malformations. Recent studies have revealed the ability of high doses of zinc to disrupt copper absorption and thereby contribute to the development of anemia.
