The many nutrition education guidelines formulated by different organizations and institutions are the frames for the program actions targeting nutrition awareness in the school-age population. But while the guidelines represent a solid starting block they still need to be backed up by programs giving concrete form to the guiding principles, a program whose efficacy is demonstrated by specific applications studies. The aim of the "Bring Fruit at School" nutrition education program is to encourage elementary school children to change their eating habits for the better. And in particular to eat more fruit, vegetables, legumes, and fish and to cut down on junk-food and sugar-sweetened drink.
