Nutrition is indispensable for human beings from the day they were born to the day they die. Besides having the right information for a balanced diet, it is also important to know how to use such information. This paper evaluates the nutritional knowledge of primary school teachers in Guzelyurt district. The questionnaire was given to 71 teachers in total and it was filled using face-to-face questionnaire techniques. The results have shown that 54.1% of the teachers in the district knew about a balanced diet and were informed about nutrition. However, it was confirmed that there is a need to organise a sustainable training programme for teachers in order to bring them up-to-date with new information and technological developments regarding nutrition.
