Abstract

Pravilne prehrambene navike u djetinjstvu važne su za podržavanje optimalnog rasta i razvoja, ali i prevenciju kroničnih nezaraznih bolesti kasnije u životu. Cilj ovog rada bio je procijeniti nutritivnu i energijsku gustoću jela koja se nude za ručak u devet osnovnih škola s područja Grada Zagreba i Zagrebačke županije. Za sva školska jela ponuđena za ručak unutar jedne školske godine izračunata je nutritivna gustoća uz pomoć validiranog NRF 9.3 indeksa, a energijska gustoća izražena je kao sadržaj energije po gramu jela. Rezultati nutritivnih i energijskih gustoća jela koja se nude za ručak međusobno su uspoređivani kako bi se utvrdili razlozi varijacija te odstupanja od normativa propisanih Nacionalnim smjernicama za prehranu učenika u osnovnim školama. Utvrđena je statistički značajna razlika u nutritivnoj i energijskoj gustoći juha i variva među školama (p<0,05). Različite vrste i količine korištenih sirovina (mesa i povrća) te dodane soli i ulja, razlozi su koji najviše doprinose utvrđenim razlikama u nutritivnoj i energijskoj gustoći jela među ispitivanim školama. Normativi najčešće ponuđenih jela školskih ručkova nisu usklađeni s normativima Nacionalnih smjernica, te je utvrđeno da jela pod istim ili sličnim nazivom imaju različitu nutritivnu i energijsku vrijednost među školama. Potrebno je nadopuniti postojeće normative i standardizirati školski ručak kako bi u svim školama djeci bila osigurana jela jednake energijske i nutritivne kvalitete.

Abstract (english)

Healthy eating habits during childhood are important in order to support optimal growth and development of child and can contribute to the prevention of chronic diseases later in life. The aim of this study was to evaluate nutrient and energy density of meals offered for lunch among nine primary schools in Zagreb and Zagreb County. The nutrient density of all school lunches, offered in one school year, were estimated by using a validated NRF 9.3 index as well as energy density which was expressed as the energy value per gram of meal. The results of nutrient and energy density of meals of individual schools were compared with each other in order to establish reasons, variations and deviations from the norms prescribed by the National Guidelines for Premature Primary School Students. There was a statistically significant difference in the nutrient and energy density of soups and stews between schools (p <0.05). Different types and quantities of meat, vegetables, salt and oil used by each school were the reasons that contributed the most to the proven differences in nutrient and energy density of meals among schools. Recipes of the most frequent meals are not in line with ones that are recommended by National Guidelines. It has been established that dishes with the same or similar name have different nutrient and energy values among schools. It is necessary to standardize existing recipes written in National Guidelines in order to provide meals with the equal nutrient and energy quality to all school children.
