A Comparative Analysis of the Contents Of Iron, Zinc, Copper, Manganese, and Calcium in the Collective Diet Of Preschool Children in the Northwestern Region of Bosnia

Abstract

Researches conducted worldwide indicate a frequent deficiency in mineral matters. Due to the increased need during the period of accelerated growth and development, children belong to the group that is exposed to the highest risk of mineral matter deficiency. Our objectives were to determine the iron, zinc, copper, manganese, and calcium intake in the collective diet of the preschool population in the in the northwestern region of Bosnia- in the Republic of Srpska and to estimate the adequacy of the application of the international food composition tables for nutrition planning relating to mineral matters. Samples of food intended for children's diet were collected in the preschool institution "Radost" (a kindergarten), in the city of Prijedor. In daily portions, Fe, Zn, Cu, Mn, and Ca contents were determined by flame atomic absorption spectrophotometry. Contents of mineral matters in daily meals were also calculated by the food composition tables. An average daily meal contained 2.86 mg of Fe, 1.71 mg of Zn, 0.19 mg of Cu, 0.21 mg of Mn, and 83.5 mg of Ca. With calculation method, contents of all minerals are significantly higher than the experimental data for all used food composition tables. The obtained results indicate a significant deficiency in mineral matters in the collective diet of the preschool population in the Republic of Srpska, a certain non-compliance with the applicable recommendations, and also suggest a need to create food composition tables for food being consumed in our region.

Coordination Complexes of Manganese and Their Biomedical Applications

“…A safe and adequate dietary intake of Mn for an adult has been estimated to 2–5 mg/kg body weight . Whenever, its daily intake is not sufficient, adequate nutrition practice is recommended . For example, use of Manganin is recommended in case of Mn deficiency .…”

Assessment of Elemental Content, Antioxidant Activity and Total Phenolic Content of Vitis sylvestris Gmelin

“…Copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn) are essential elements for human health and should be taken into the body to maintain many important metabolic activities in the human body (1,2). These elements play an essential role in the growth, development, and health of the human body (2)(3)(4)(5). We can find Cu in the structure of many enzymes; similarly, Zn is defined as a cofactor in some enzymes and is involved in various metabolic activities.…”
