According to the guidelines(5), the school lunch should provide about one-third of daily energy intake. The proportions of energy nutrients should be as follows: proteins 15 %, fats 30% and carbohydrates 55 %. The nutrient composition of the meals should be monitored by calculating the nutrient density – the amounts of some indicator vitamins and minerals per MJ. The school meal should contain all the components of a well-balanced meal: a main course, salad, bread and milk. The lunch is preferably served between 00?11 and 00?12 hours, and the time for eating should be at least half an hour. School canteens have self-service system, and therefore pupils
can choose their own meals. Teachers or catering personnel usually supervise and assist only the youngest schoolchildren. Special diets are offered for those with food allergies or other special dietary requirements.
