Shiitake mushrooms are rich in such vitamins and minerals as vitamin B2 and 12.1 %, vitamin B5 – 30 %, vitamin B6 and 14.7 %, vitamin PP – 19,4 %, potassium – 12,2 %, phosphorus – 14 %, manganese – 11,5 %, copper – 14,2 %
- Vitamin B2 is involved in redox reactions, contributes to the susceptibility of the colors of the visual analyzer and the dark adaptation. Insufficient intake of vitamin B2 is accompanied by a violation of the health of the skin, mucous membranes, impaired light and twilight vision.
- Vitamin B5 is involved in protein, fat, carbohydrate metabolism, cholesterol metabolism, the synthesis of several hormones, hemoglobin, and promotes the absorption of amino acids and sugars in the gut, supports the function of the adrenal cortex. Lack of Pantothenic acid can lead to skin lesions and mucous membranes.
- Vitamin B6 is involved in maintaining the immune response, the processes of inhibition and excitation in the Central nervous system, in the transformation of amino acids, tryptophan metabolism, lipids and nucleic acids contributes to the normal formation of red blood cells, the maintenance of normal levels of homocysteine in the blood. Insufficient intake of vitamin B6 is accompanied by loss of appetite, impaired the health of the skin, the development of the found, and anemia.
- Vitamin PP is involved in redox reactions and energy metabolism. Insufficient intake of vitamin accompanied by a disturbance of the normal condition of the skin, gastrointestinal tract and nervous system.
- Potassium is the main intracellular ion that participates in the regulation of water, electrolyte and acid balance, is involved in conducting nerve impulses, regulation of blood pressure.
- Phosphorus is involved in many physiological processes, including energy metabolism, regulates the acid-alkaline balance, is part of the phospholipids, nucleotides and nucleic acids needed for mineralization of bones and teeth. Deficiency leads to anorexia, anemia, rickets.
- Manganese is involved in the formation of bone and connective tissue, is part of the enzymes involved in the metabolism of amino acids, carbohydrates, catecholamines; required for synthesis of cholesterol and nucleotides. Insufficient consumption is accompanied by growth retardation, disorders of the reproductive system, increased fragility of the bone, disorders of carbohydrate and lipid metabolism.
- Copper is part of the enzymes with redox activity and is involved in iron metabolism, stimulates the absorption of proteins and carbohydrates. Involved in the processes of human body tissues with oxygen. The deficiency is manifested by impaired formation of the cardiovascular system and skeletal development of connective tissue dysplasia.
