title: [Study of the degree of discrepancies between analytical and theoretical results of the evaluation of daily food rations].
abstract: Thirty-six daily food rations given as the basic diet to children in two paediatric hospitals in the City of Cracow were analysed. Using laboratory methods in these meals the contents were analysed of protein, fat and carbohydrates and the energy value was determined. Parallelly the theoretical values++ of these parameters were calculated using "Tables of Composition and Nutritional Value of Food Products". For the assessment of the differences between analytical and theoretical values the following were used: 1) deviations of the values obtained in analysis from the theoretical ones accepted as 100%, 2) indices of differences. The general characteristics of the results was determined by the arithmetical++ mean, standard deviation, variance coefficient and 95% confidence limits. The results shown in the study demonstrate that the lowest mean deviation from the theoretical values was found in the case of protein (1.1%) and energy value (12.5%) with the largest one for carbohydrates (38.9%).
