Summary
In 2012, the Kids University for Cooking Foundation BV has developed a nutrition education programme called 'Kokkerelli Learning Street'. This innovative programme aims to teach primary school students from study years 5-8 where food comes from, how it is processed, and how it can be used for the preparation of a healthy meal.
The Kokkerelli Learning Street is offered to primary school children in the region of Venlo, the Netherlands. The present study will investigate the effects of the Kokkerelli Learning Street on several determinants of children's fruit and vegetable intake. Based on the literature and the aims of the Learning Street, five relevant determinants are selected: (i) knowledge; (ii) taste preferences; (iii) intention; (iv) skills; and (v) attitude.
Using child-reported questionnaires, the present study aims to answer the following key questions:
What are the short-term and longer-term effects of the Kokkerelli Learning Street on children's:
* Knowledge regarding fruit and vegetable consumption?
* Intentions regarding fruit and vegetable consumption?
* Attitude regarding fruit and vegetable consumption?
* Liking of fruit and vegetables?
* Skills regarding fruit and vegetable preparation?
* Fruit and vegetable intake?
