Cowpeas (some Chinese), the leaves are rich in vitamins and minerals like vitamin B1 – 23.6% of vitamin B9 – 25,3 %, vitamin C – 40 %, potassium – 18,2 %, manganese – 25.5 per cent, copper – 19,1 %
- Vitamin B1 is part of key enzymes of carbohydrate and energy metabolism, providing the body with energy and plastic compounds as well as the metabolism of branched-chain amino acids. The lack of this vitamin leads to serious disorders of the nervous, digestive and cardiovascular systems.
- Vitamin B9 as a coenzyme involved in the metabolism of nucleic and amino acids. Folate deficiency leads to impaired synthesis of nucleic acids and protein, resulting in inhibition of growth and cell division, especially in a fast-proliferous tissues: bone marrow, intestinal epithelium, etc. Inadequate intake of folate during pregnancy is one of the causes of prematurity, malnutrition, congenital malformations, and child developmental disorders. Shown the strong Association between levels of folate, homocysteine and risk of cardiovascular disease.
- Vitamin C participates in redox reactions, the immune system, helps the body absorb iron. Deficiency leads to looseness and bleeding gums, nasal bleeding due to increased permeability and fragility of blood capillaries.
- 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.
- 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.
