Principles of rational nutrition of young children:
1. The principle of nutrition physiological adequacy.
2. The principle of nutrition energy adequacy.
3. Multi-component balance of the diet for all replaceable and irreplaceable nutritional factors, including proteins, dietary
fats, various classes of carbohydrates, mineral salts and vitamins.
4. The maximum variety of the diet with the gradual introduction of new dishes.
5. Technological and culinary processing of food products and meals appropriate to the age and health state.
6. Nutrient principle pre-security [1].

The consequences of improper nutrition of children are manifested in the process of life, under adverse external
conditions, diseases, as well as increased academic workload at school. For meeting the physiological needs of children for
nutrients and energy, as well as good digestibility, satiety, academic performance, it is important to develop in children a
conscious adherence to a rational diet. Proper nutrition in adolescence from 10-14 to 18 years, which
plays an important role in
the formation of a maturing organism. In adolescence, there are significant changes in the body's response to various
environmental factors, their body weight increases, there is a rapid growth of tissues and body systems, as well as puberty [1,2].
In the period from 10 to 16 years, there is an accelerated growth
of the body, the active formation of endocrine glands, a
number of parts of the brain are formed.
Uneven maturation of various organs of children during this period leads to increased fatigue, excitability, irritability, and
negativism. According to statistics, about 30% of chronic diseases in adolescents studying in educational institutions are
associated with malnutrition.
In recent years, due to malnutrition of adolescents, diseases of the gastrointestinal tract, metabolic disorders and anemia
have increased among them. There is a deficiency and lack of vitamins C , B1, B2, beta-carotene, iron, calcium, iodine , zinc,
polyunsaturated fatty acids and dietary fiber. The most important principle of rational nutrition of children and adolescents is
compliance with the calorie content of the diet to the energy costs of the body [3].
Food is a necessary building material for the growth and development of a young organism. Energy expenditure in
children and adolescents is significantly higher than in adults. The nutrient and energy requirements of children and adolescents
are shown in Table 2.

Insufficient calorie content of the diet leads to rapid exhaustion and dysfunction of all organs and systems [1, 4].
The diversity of the diet is the main condition for ensuring its balance. Balanced diet for children and
adolescentsachieved by including in the diet a diverse range ofproducts of animal and vegetable origin. Daily in dietsnutrition of
children and adolescents is important to include meat, milk, butter andvegetable oil, sour-milk drinks, rye and
wheat bread,
andalso fish, eggs and cheese.
Thus, adherence to the principles of healthy nutrition and the formation of a balanced diet will ensure the proper
development and health of children and adolescents for the next years of life.
