The diploma paper aims to appraise the composition of menu offered to pupils aged seven to twelve attending the Elementary School (ES) based in Suché Vrbné, a quarter of České Budějovice. The menu was assessed for its contents of macronutrients and a range of chosen micronutrients considered to meet nutritional demands of school children. The research covered 64 examinees (of both sexes) from the second, fourth and sixth grades, and was organized as a test of their dietary habits and physical a tivities. The paper deals with: -Nutritional quality of school lunches; -Weights and statures of children from the relevant grades measured at the beginning and the end of the appraised span of time, with the observed changes evaluated; -Average cost spent to prepare one lunch; -Variety of the food and the numbers of specific dishes taken in a month; -Adherence to the recommended alimentary basket; -Weights of the different components of lunches; -Nutritional test designed to examine dietary habits and physical activities of c ildren aged 7 to 12; -Changes in the diet of children moving up to the senior stage of the Elementary School; -Formulating hypotheses focused on drinking regimen, Body Mass Index (BMI) and physical activities. Percentage of nutrients derived from lunch, represent the proportion of recommended daily intake for the day. The ideal figure of 35 % of the recommended daily energy intake was achieved only in girls of the 4th grade. The other categories of boys and girls ranged between 5 % and 9 %. As regards proteins, these were supplied in the above-the-limit quantities to the 2nd and 4th graders, while the 6th graders received 79,65 % to 82% of the recommended daily intake. Fats kept at the optimal level of 30 % to 35 %. Saccharides stayed at the low level of 19 % to 24,69 % for the entire time of monitoring. Fiber was found to maintain the acceptable level of 29 % to 37,41 %. As regards the macroelements, calcium supply was insufficient - at 15,0 % to 18,46 % only a small portion of what is desirable. Magnesium intake was at 41,86 % to 59,1 %. Potassium reached on average 53,6 % to 59,66 %. As to microelements, iron was supplied at 42,37 % to 48,91 %; zinc at 41,15 % to 52,91 %; selenium at 59,1 % to 175,21 %. Vitamin A reached 60,78% to 89,23 %; vitamin E was at 38,66 % to 55.1%, and vitamin C at 58,81 % to 66,0 %. Vitamin B6 was supplied in the quantity of 38,50 % o 47,83 %. Vitamins B6 and B12 were supplied in above-the-standard quantities for the whole monitored period. Measurements of weights and statures were related to the age and then used to calculated the BMI - thus one 2nd grade girl was found overweight and one boy and another girl of the same grade were found obese. Pupils of the 4th grade kept within the optimal figures. In the 6th grade two girls and four boys registered overweight. Expressed in percentages, the research has showed that in the 7 to 12 age bracket 3.2% of children were obese and 9.15 overweight. The average cost of lunch preparation was 42 CZK. The numbers of specific dishes were revealed inadequate for pulses and fish. The share of fruit was duly met while vegetables were insufficient. Low was observed also the proportion of milk and sweet & meatless dishes. Conversely, the frequency of dishes made of chicken and pork was excessive. Yeast and pulse soups were served optimally, as suggested by the Ministry of Health. Inspection carried out in view of the alimentary basket specified in Decree 107/2005 disclosed these values as average for the entire period of interest: meat 92,9 %; fish 69,4%; milk 54.8 %; milk products 72.9 %. Fats were supplied at the level of 69,3 %; sugar 46 %; vegetables 59.9%; fruit 124%; potatoes 87,4 %; and pulses 54,4 %. |
