Educational resources such as school canteens and other food services are crucial. In addition to being an essential component of the school environment, they play a significant role in providing food for students and the school community.

The school canteen should support and enhance students' learning while reflecting the institution's educational objectives. When eaten regularly, the food served in the school canteen may make up to one-third of a student's daily caloric intake, substantially impacting their nutrition and general health.
