[Modern trends of research in nutritiology and nutrition hygiene]

Advances in instrumental analysis and new knowledge in biology and medicine have allowed nutritiology and nutrition hygiene: 1) to go from studies of dietary intake of the population and the establishment of standards nutrient and energy needs to ensuring of public health and prevention of diseases by changing the composition and structure of nutrition; 2) to assume that the nutrition includes all the processes of cell and organism vital functions; 3) to develop an individualized nutrition and dietetics purposeful; 4) to evaluate energy value of ontogeny; 5) to ensure food safety at all stages of its manufacture; 6) to combine many disciplines into a single unit to achieve scientific and practical problems. Nutritiology achievements of the 21st century will be based on the development of cell biology as a basis for systematic studies of ontogenetic development of a unicellular or multicellular organism on the external factors, including food. OMICs-disciplines should be used for these purposes in order to understand the physiological meaning of transmission and coding signals to food interaction of genes, proteins, metabolites inside cells or in the organism, to reveal the mechanisms of encoding cell responses to these specific interactions. The nutrition process covers all aspects of life of the cell and organism. Postnatal ontogenetic development of placental mammals has its own specific energy dimension. Consumption of 100 kJ/kg body weight provides 1/50,000 of their ontogeny. A hypothesis of lifespan regulating by changing the rate of ontogenetic development (aging) of organs and tissues of mammals, depending on the amount of energy consumed and food has been offered. Heterochronicity of internal organs and tissues aging depends on the work they are doing and the specific impact on them of food and substances. Research should be directed at identifying the regulatory properties of food substances on pre- and postnatal ontogenetic development of human. This knowledge will serve as a basis for the development of care to ensure the health of the population.
