Information and computer support of healthy nutrition as a current method of health saving and food hygiene in modern environmental conditions

In the modern world the problem of a proper diet choice needs a scientifically based technical support service, which is associated with global changes in the lifestyle and the environment. Thousands of diets, thousands of food products, where each product contains dozens of nutrients, hundreds of individual health characteristics — all this makes it almost impossible to select an optimal diet without involving of modern information technologies. One of the main obstacles to the formation of an optimal diet is the existence of two conflicting requirements to the diet of modern man. The first requirement is a decline in caloric intake, which is caused by a decrease in the physical activity. The second is the need to increase the nutrient density of the diet that cause a gain in human needs for vitamins and minerals, and a fall in the amount of vitamins and minerals in food. One possible solution is to create a network technology that supporting an individual nutrition choice. The article presents the concept and architecture of the system of the assessment, planning and optimization of personalized diets. The theoretical concept of the proposed system and Web-based technology is based on a dynamic two-level shaping information. On the first level of the individual diet is analyzed for the compliance with modern scientific ideas about healthy nutrition, which are reflected in the pyramid of human nutrition. The second, more complex and detailed version of the assessment of individual diet allows you to perform an analysis and diet plan based on the most important nutrients. For this we need to provide data on all food products that you have eaten for a period of time. The proposed Web-technology can be implemented not only in Internet, but also as a mobile application, and it will be useful for individual and family use, for the implementation in schools, health centers and hospitals, for the state control of the nutritional status of people, at centers of state epidemiology service. Also developed Web-technology is designed to solve the problems of education and the promotion of knowledge on issues of food hygiene, a healthy lifestyle and prevention of aging.
