Abstract

Razdoblje studiranja predstavlja prekretnicu u ţivotu većine studenata i često rezultira promjenama ţivotnih navika, što se odraţava i na kvalitetu prehrane. Redovita konzumacija voća i povrća temelj je pravilne prehrane i prevencije razvoja kroničnih bolesti što se pripisuje i prisutnim fitokemikalijama. Lutein i zeaksantin glavni su karotenoidi u ljudskom organizmu. Njihova prisutnost u ljudskom organizmu u cijelosti je posljedica konzumacije namirnica biljnog porijekla. Cilj rada bio je procijeniti dnevni unos luteina i zeaksantina u studentskoj populaciji. U istraţivanju je sudjelovalo 149 ispitanika, a podaci su prikupljeni putem upitnika o učestalosti konzumacije hrane (FFQ). Veći unos luteina i zeaksantina meĎu ispitanicima ostvaren je konzumacijom povrća (95%) nego voća (5%). UtvrĎen prosječan unos luteina i zeaksantina meĎu studentima od 3088,3  2487,2 g/dan nije dostatan za ostvarenje povoljnog učinka ovih fitokemikalija na zdravlje koji se ostvaruje unosom od 6000 g/dan, stoga je potrebno je povećati unos voća i povrća bogatih luteinom i zeaksantinom.

Abstract (english)

The study period represents a milestone in the lives of most students and often results in changes in life habits, which is reflected in the quality of nutrition. Regular consumption of fruit and vegetables is the foundation for proper nutrition and prevention of chronic diseases, which is attributed also to the present phytochemicals. Lutein and zeaxanthin are the main carotenoids in the human body. Their presence in the human body is entirely a consequence of the consumption of foods of plant origin. The aim of the study was to evaluate the daily intake of lutein and zeaxanthin among students. In the reasearch, 149 students participated, and data were collected through a Food Frequency Questionnaire (FFQ). Greater intake of lutein and zeaxanthin among the students was achieved by eating vegetables (95%) than fruits (5%). The average intake of lutein and zeaxanthin among students of 3088.3  2487.2 g/day is not sufficient to achieve the beneficial effect of these phytochemicals on health, which is achieved by the intake of 6000 g/day, therefore it is necessary to increase the intake of fruits and vegetables which is rich in lutein and zeaxanthin.
