Pupil lunches was one of the oldest social welfare projects in Greece. The purpose of school meals was to provide, either free of charge or for a small fee, mainly at noon, to the underfunded pupil, a hot and nutritious breakfast supplementary to daily nutrition, in response to the needs of his/her growing body and needs of school work. The consequences of malnutrition in childhood were known. Reducing the vitality and energy of the child, slowing down, decreasing their resistance to infections, mental lethargy, etc. Malnutrition in particular was to blame for tuberculosis. Student meals were, therefore, the basis of school perception and care, the most positive and effective measure to protect the health of sick and malnourished students, the strongest weapon of preventive care. And if they were of great importance before the war to school canteens, their value after the war for the restoration of the health of Greek children, who were severely tested by war and occupation, can be understood. The purpose of submitting this study to the academic community is to investigate and compare the institutional arrangements, processes, and ways in which the politics of student meals was formulated, organized and practiced in the Greek educational system during 1931 - 1935, 1936 - 1940 and 1941-1967.
