ИСТИНА

Every person faces a very fast life rhythm; people have to have healthy constitutions, strong nervous systems, and good memories. In speaking about nutrition, one should always take into account the triad soil–plant (animal)–human. People get nutritious elements from products of plant and animal origin, which take nutrients from soil. Soil is the main source of most microelements (both those necessary and those harmful to people). The toxicity or lack of certain microelements in soil may affect the quality and taste of food. We revised the existing literature to reproduce the chain of 10 major microelements in triad. Mechanisms of microelements’ transport from one medium to another were discussed with an emphasis of pedogenetic processes, which might lead to concentration or diffusion of elements in comparison with the parent rock. We proposed an approach based on hypothetical concentration of microelements in food depending of dominant rocks and soils in particular areas: Sichuan province in China, Republic of Uzbekistan, and Central-Northern region of Mexico, taking into account the dietary peculiarities in each region. The region with the lowest concentration of micronutrients in dairy ration was the Sichuan province, where all the micronutrients except of Mn were present in food in the quantities less than the required daily dose. In Central Mexico the daily amount of Cu in food was in the recommended range, and other elements above this range. In Uzbekistan all the elements were potentially present in food in amounts higher than the recommended amount.
