Nutritive support for students through the introduction in the diet of specialised products can prevent alimentary diseases, promote growth and development of students in a period of increased emotional and intellectual loadsMethods
Surveyed 50 students, 12–13 years old. The first group (n=21) with normal body weight for age and group II (n=14) underweight received in addition to the diet dairy product ’Growth Formula the Standard’ 1 time a day or a month. Control group (n=15) – did not receive product. One serving is 200 ml/day corresponds to 10% of protein requirements, 14% in the vitamins and minerals from consumption. The efficacy was assessed according to the emotional status (test SAN) at 14-th and 28-th days of receiving the product and renal excretion of amino acids in the dynamics.Results
The analysis of psychophysiological status revealed positive dynamics of the SAN after receiving the product in 73% of the students. The positive dynamics of body mass index on the background of the reception of the product, more significant in group II pupils underweight by age. The content of free amino acids (AA) in the urine – methionine, leucine, lysine after receipt of the product was below the initial levels (p<0.05). In the control group dynamics of the indicators was expressed slightly.ConclutionS
Dynamics of excretion of AA power due to their use in metabolism during growth, especially in children with deficiency of body weight and involvement of AA in metabolism, with hormonal changes and increased intellectual activity. The improvement in mood in children is correlated with changes in indicators of leucine and isoleucine that support serotonin involved in the regulation of emotional state. The use of a specialised product in schoolchildren is an effective method for the normalisation of nutritional and emotional status.
