In designing curricula of subjects in which nutrition contents appear, it is necessary to take into account
the level of cognitive development of children, the latest findings of the nutritional science and to clearly define
individual concepts used in the nutrition education. Considering the cognitive development level of a child, it is
to be expected that more complex problems in the area of nutrition (for example, planning healthy nutrition,
and classifying food in groups in reference to the prevailing nutrient, energy needs of the body) would be more
easily solved by children in higher grades of compulsory education, when at the age of 11 and above, they pass
to the formal operational stage of their cognitive development. Continuous education must be properly planned
and upgraded with an interdisciplinary and constructivist approach that allows development of processing
knowledge, needed to critically evaluate one’s own eating habits.
