Assessment and optimization of the nutritional situation in Croatian boarding schools

The aim of this study was to assess the nutritional quality of the food supply in Croatian boarding schools and to provide suggestions aimed at its improvement. The work is based on a nutritional survey and nutrition optimization. The survey assessed the food supply in female, male and co-educational boarding schools in Zagreb, Croatia. Particularly, the diets of students aged 15– 19 years were investigated and the relationship between students’ anthropometric measurements and the supply of energy, protein, fat and carbohydrates was analysed. Based on the survey results, nutrition optimization was applied to determine diets meeting the recommended dietary allowances (RDAs) of selected nutrients at least cost. The survey showed that the diets provided in Croatian boarding schools are generally characterized by an oversupply of energy and fat to female pupils and an undersupply of many micro-nutrients to pupils of both genders. This seems to promote the development of obesity in female students. Furthermore, it could be shown by means of nutrition optimization that the nutritional situation in the boarding schools could easily be improved by a reasonable selection and combination of dishes that would also lead to a reduction of food costs. Menu planning by means of nutrition optimization could help to improve the nutritional quality of the food supply in Croatian boarding schools and simultaneously decrease the corresponding food costs.
