Hawaiian mountain yam, raw rich in vitamins and minerals such as: potassium – 16,7%, manganese – 12,1%, copper – 11%
- 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.
- 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.
