There is a need for a more sustainable diet in many countries. Using Mediterranean principles could provide a possible answer. The principles of the Mediterranean diet and suitability to the Nordic diet have been discussed in courses mainly for Norwegian food and health teachers and students visiting Greece. What benefits do the participants experience after returning home and how do they apply their new knowledge in Norwegian conditions? We studied the themes from the exam papers to find out which knowledge the participants acquired from the course, and how they transferred their knowledge about the Mediterranean diet to Norwegian conditions. We also conducted a survey among the participants; they reported that they felt they benefited from the course. It seems the students are able to translate their knowledge about Mediterranean diet to Norwegian conditions, and the teachers who participated in the course used their knowledge in teaching. Most of the participants use this knowledge in their daily lives.
