Ecological and physiological feature of some microelements and their concentration in vegetable products

Abstract

In this work, providing human body with essential food components was assessed and the physiological role of chemical elements - iron and manganese - was considered. They are among key nutrients essential for human body. Iron plays an important role in the functioning of immune system; it is necessary for the full functioning of brain and nervous system. Iron deficiency can cause iron deficiency anemia which leads to a slowdown in children's mental and psychomotor development. Manganese has an effect on the functioning of nervous system; it participates in exchange of impulses between nerve cells and regulated reproductive function of the body. This element promotes insulin secretion and metabolism of fats and carbohydrates, it is necessary for blood formation, metabolism, functioning of musculoskeletal system, immunity, hair growth, normal skin, and is an antioxidant. Microelementoses with metabolic disorders of substances such as iron and manganese can be caused by deficiency, excess or redistribution between the reserve and functional funds of microelements under consideration. Based on this, we can summarize that iron and manganese are indispensable microelements for human body; their deficiency results in undesirable pathological metabolic disorders. Considering the relevance of this problem, the analysis of the content of chemical elements in samples of vegetable crops was carried out. These results a high iron content in beets and potatoes what indicates their nutritional value; sufficient consumption of them covers the daily requirements for manganese and iron.
