Abstract

Prehrana bogata namirnicama niske energetske gustoće, kao što su voće i povrće, povezana je s manjim rizikom od pretilosti i boljim zdravstvenim stanjem, ali je riječ o skupljoj hrani, dok je hrana visoke energetske gustoće, ona bogata šećerom i mastima, jeftinija i pristupačnija, ali je povezana s rizikom od pretilosti i raznih kroničnih bolesti. Cilj ovog rada bio je prikupiti podatke o cijeni hrane niske i visoke energetske gustoće i pokazati kako cijena i ekonomska dostupnost hrane imaju utjecaj na odabir hrane i zdravlje potrošača. Podaci o cijeni i energetskog gustoći su prikupljeni u tri trgovine na području grada Zagreba za ukupno 137 sirovih namirnica i industrijskih proizvoda. Rezultati pokazuju da je hrana niske skuplja od one visoke energetske gustoće (npr. 1000 kcal iz zelenih tikvica (15 kcal/100 g) košta 124,20 kn, a 1000 kcal iz kiselog vrhnja (138 kcal/100 g) košta 13,99 kn). Utvrđena je negativna korelacija (r=-0,40; p<0,001) između energetske gustoće (kcal/100 g) i cijene 1000 kcal. Potrebno je osmisliti strategije kojima bi se cijena hrane niske energetske gustoće smanjila, kako bi se potaknuo njen unos i poboljšala kvaliteta prehrane, a time i zdravlje potrošača.

Abstract (english)

Low-energy density diet, high in fruits and vegetables, is related to lower obesity risk and to better health status, but is more expensive. High-energy density diet, high in sugar and fat, is cheaper and more affordable, but is related to higher obesity and chronic diseases risk. The aim of this work was to collect food prices according to their energy density (low vs. high) and to show how food affordability affects food choice and consumers health. Data was collected from three food stores in Zagreb for 137 raw foods and processed food products. Results show that low-density food is more expensive than high-density food (for example, 1000 kcal from green zucchini (15 kcal/100 g) cost 124.20 kn while 1000 kcal from sour cream (138 kcal/100 g) cost 13.99 kn). Negative correlation was observed (r=-0.40; p<0.05) for energy density (kcal/100 g) and price of 1000 kcal. Therefore, it is necessary to develop strategies in order to reduce cost of low-energy density food and encourage its intake since it would improve diet quality, which could lead to better costumers' health.
