Abstract

Pravilna prehrana je izuzetno važna tijekom djetinjstva jer omogućuje optimalni rast i razvoj djeteta te može pridonijeti prevenciji pojave kroničnih bolesti kasnije tijekom života. Cilj rada bio je procijeniti nutritivnu i energetsku gustoću ručka u osnovnim školama s područja Grada Zagreba i Zagrebačke županije pomoću mjerenja otpada hrane s tanjura te ispitati povezanost količine otpada hrane s nutritivnom gustoćom obroka. Nutritivna gustoća je procijenjena pomoću NRF6.3 indeksa, a energetska gustoća je izražena kao energetska vrijednost po gramu obroka. Rezultati su se uspoređivali s obzirom na model javne nabave unutar sezona. Prosječna nutritivna i energetska gustoća ručka nije se statistički značajno razlikovala između škola s obzirom na model javne nabave. Prosječna količina otpada je bila 21-23% od servirane hrane po učeniku/dan unutar sezone, a najveći dio ukupnog otpada čine povrće i škrobna hrana. U sezoni jesen/zima postoji statistički značajna negativna povezanost postotka bodova NRF indeksa konzumirane hrane i ukupnog otpada hrane za škole modela 1 (p=0,015) i za škole modela 2 (p=0,021). U sezoni proljeće/ljeto postotak bodova NRF indeksa konzumirane hrane statistički značajno je bio veći za škole modela 2 u odnosu na škole modela 1 (p=0,001). Statistički značajna negativna povezanost je utvrđena između postotka bodova NRF indeksa konzumirane hrane i otpada iz skupine povrće za škole modela 1 (p=0,042) te za škole modela 2 (p=0,004).

Abstract (english)

Healthy diet is very important during childhood because it provides 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 the nutrient and energy density of lunch in primary schools in the area of Zagreb and Zagreb County by measuring plate waste and to examine the correlation between the amount of food waste and the nutrient density of meals. The nutrient density was estimated by the NRF6.3 index, and the energy density was expressed as the energy value per gram of meals. The results were compared according to the model of public procurement within the season. The average nutrient and energy density of the lunch was not significantly different between schools according to the model of public procurement. The average amount of food waste was 21-23% of served food per pupil/day, and the most food waste was from vegetables and starch food. In the fall/winter season there was a significantly negative correlation between percentage of points of NRF index for consumed food and total food waste for the schools of model 1 (p=0.015) and for the schools of model 2 (p=0.021). In the spring/summer season, the percentage of points of NRF index for consumed food was significantly higher for the schools of model 2 compared to the schools of model 1 (p=0.001). The significantly negative correlation was determined between the percentage of points of NRF index for consumed food and food waste from the vegetable category for the schools of model 1 (p=0.042) and for the schools of model 2 (p=0.004).
