Background:
The “School Lunch” program was initiated by the Government of Mongolia in 2006. The purpose of our study was to assess nutritious values of the meals and food products being given to pupils of general education schools in the frame of the program.
Materials and methods:
Nutritious values of 32 samples of school canteen meals and food products of 5 general education schools were determined using chemical analysis methods.
Results:
The average calorie content of the analyzed meals was 181.07-271.08 kcal, and the average content of vitamin C was 0.28-0.84 mg/g. The energy value of bakery products was high (110.97-436.23kcal) whereas their vitamin C content was low (0.34 mg/g). The calorie content in dairy products was reasonably high (46.17-52.85kcal), and the average level of calcium was 95.84-103.1mg/g, of iron was 0.7-1.7mg/g and of vitamin C was 0.28-0.84 mg/g.
Conclusions
1.The study results highlight the necessity of broadening the variety of food products given to schoolchildren in the frame of the “Lunch” program. 2.Fruits and vegetables, the main source of minerals and vitamins, make a small percentage of the food products given to school children, and bakery products rich of calorie prevail in the menu.

Introduction
In recent years it has been observed epidemiological transition in the world population’s morbidity and mortality causes, indicating a shift from communicable diseases to non-communicable diseases. In 2012, cardiovascular diseases alone accounts for 30 per cent of all deaths in the world. In Mongolia, non-communicable diseases are growing steadily and becoming the leading causes of morbidity and mortality of population. According to the Global School-based Student Health Survey-Mongolia 2010, overall, 19.3 per cent of school children had 4 or more nutritional risk factors of NCD and 8,3 per cent of students were overweight and 0,8 per cent were obese. Above mentioned study shows that, the prevention of NCD should be started from childhood, improving the consumption of fruits and vegetables for school snack and lunch is important in the prevention of NCD among school children. The study is aimed at determination of types, consumption and chemical composition of food products
and meals provided in school snack program.
Scope and methods of investigation
The investigation was performed in Ulaanbaatar and Tuv aimag. Under the our investigation included a totally 14 school canteens of Ulaanbaatar and Tuv aimag. Consumption of Food products was investigated using the Food Consumption Questionnaire method. All managers of school canteens interviewed by well-trained researchers using the time from 20 to 30 min for each of them. Food samples were obtained, keeping in cool boxes, transported to the Public Health Central Laboratory of National Center of Public Health, Mongolia. Chemical composition of food and snack samples were investigated according to the related standard methods for determination of protein, fat, carbohydrates, Vitamin C, Calcium.
Results
Consumption of vegetables and local fruits for school snack and meal was not enough for prevention of NCD among school children. Use of milk and milk products for school snacks and lunch were obtained only 1-3 times during the 10 days, which is too poor consumption. According to the results of chemical analysis, 83.4 per cent of all food samples had calories less than 340 kcal, which is the required value of calories of school snack per one student. With regard to protein level 50 per cent of samples had 2.57-7.7grams of protein, which is lower than the recommended level of 10-12 gr. Fat level of samples were ranged between 7.2-1.97 grams and 95.5 per cent of samples had lower fat content compared to the recommended value of 9.0 grams. When 68.7 per cent of samples had 4.5-38.03 grams of carbohydrates, which is lower than the recommended amount, some 4.5 per cent of samples had higher carbohydrates compared to the recommendation. Amount of vitamin C in school snack was extremely lower than the recommended amount that vitamin C was found between 0.02-2.31mg, satisfying only 10 per cent of the national recommendation of vitamin C amount for school snack. Amount of Calcium in milk products of school snack and meals was also low than recommended level.

Background:In the scope of the “School Lunch” program initiated by the Government of Mongolia, pupils of primary schools are served with meals prepared in school canteens and food products provided by food manufacturers. The safety of the provided food products must be monitored and evaluated. The purpose of our study was to evaluate the safety of the meals and food products being given to pupils in the frame of the above program.Materials and methods:Nutritious values and safety of 31 samples of school canteen meals and food products of 5 general education schools were determined using microbiological analysis methods based on Mongolian national standards. Results:The analysis results revealed that the total number of microbes in canteen meals fluctuated between 1х102 and 4х102, and no pathogens were detected in the analyzed samples. The quality of all pastry products met the Mongolian standard hygiene requirements. The variation of the total number of microbes in dairy products was 2х105 -4х105, and no pathogens were found in dairy products.Conclusion:Microbiological analyses show that the food products supplied by the contractual companies in the frame of “Lunch” program and meals from the school canteens meet Mongolian hygiene requirements.
