Effectiveness of enriched bakery products for school meals
Abstract
The article presents the results of studies of the influence of enriched bakery products “Yunost” and “Ranitsa” on the parameters of protein and mineral metabolism, as well as on the antioxidant protection of the body of schoolchildren. Prolonged inadequate and unbalanced nutrition of schoolchildren caused a deviation in the exchange of minerals: daily excretion with urine of calcium and magnesium was at the lower limit of the norm, phosphorus inorganic - exceeded the upper limit of the norm. The inclusion of enriched bakery products “Yunost” and “Ranitsa” in students’ rations helped to normalize the indices of mineral metabolism. In the examined observation group, excretion of calcium increased from 2.52 to 2.76 mmol / day (p <0.01), which indicates a higher content in the body of schoolchildren. The improvement in the availability of calcium to the organism of students is also confirmed by the dynamics in the calcium / creatine ratio, which significantly improved from 0.14 to 0.17 (p <0.01). Comparative analysis of changes in the state of reserves of the system of antioxidant protection of pupils against the background of correcting the actual nutrition of enriched bakery products showed a statistically significant increase in the number of individuals whose values for total AOA bio media (saliva and urine) were within the norm and above normal. At the same time, more pronounced changes in AOA parameters were established in saliva (p <0.001) than in urine (p <0.01) in the children of the observation group. Thus, the inclusion of enriched foods in school rations leads to a normalization of metabolism, a decrease in the manifestations of microsymptoms of micronutrient deficiency, which confirms the effectiveness and expediency of using these products to correct the actual nutrition of students.
