Abstract
To develop recommendations for the optimal consumption of food items considering the features of the Far North regions and the regional specificity of mineral composition, the content of 25 chemical elements was analyzed in the food items of local origin and those transported to the territory of the Magadan Region. It is determined that a portion of beef from cows grown in Magadan contains substantially higher amounts of calcium, sodium and phosphorus than beef samples brought from other regions. Locally produced beef liver contains higher concentrations of iron, iodine, manganese, and zinc. Locally produced pork contains significantly higher amounts of copper ( p = 0.01) and iron ( p = 0.1) in comparison with pork transported from other regions. Evaluation of microelement concentrations in vegetables in comparison with imported samples shows that local carrots contain higher selenium concentration, local cucumbers - higher potassium, copper, and manganese, beetroot is richer in selenium and zinc, with its portion being able to meet fully the daily demand for manganese. In all the analyzed vegetable samples imported from China, nickel content is higher than in local products. In addition, Chinese carrots contain reliably higher concentrations of boron and cobalt, tomatoes and cucumbers contain higher levels of chromium and vanadium, while silicon content is higher in vegetables from the Magadan Region. At the same time, neither of the examined samples exceeds the permissible levels of toxic elements.
