Evaluation of orientation and efficiency of schoolchildren nutrition in recreational period

Abstract

Background: determination of antioxidant orientation schoolchildren of nutrition in recreational
period and evaluation of its efficiency. Methods: it is studied nutrition of 221 schoolchildren aged 7-15 years
old at children’s recreational institution. It is used the method of analysis of menu production records with
the subsequent calculation of average daily set of foods, specifying its chemical composition and energy value.
The efficiency of nutrition was estimated according to indicators of vitamin and antioxidant statuses. The
dynamics of excretion of vitamins C, B2 and B6 was studied in hour-long portion of urine. The features of
urine bio-chemiluminescence in 9 indicators are estimated. Studies were conducted on 2-3 and 22-23 days
of recreation. Result: it is confirmed the existence of antioxidant direction of nutrition by means of sufficient
content of total protein, aromatic amino acids, phospholipids, tocopherols, B vitamins, S, Zn. Content of
Se, ascorbic acid in food ration was insufficient. It is determined 16 indicators which are most objectively
characterized antioxidant direction of food ration. Conclusion: The nutritional factor influenced positively on
vitamin and antioxidant status of organism. The determined correlation dependences between indicators of
biochemiluminescence and level of vitamins egestion confirmed the efficiency of nutritional factor for influence
on schoolchildren’s health.
