Colegio Gran Bretaña provides daily snacks and lunches for all students. The school aims to encourage healthy eating by providing a nutritionally balanced menu. A vegetarian menu is available. The daily menu is sent home at the start of each month. It is the policy of the school to encourage students to eat and try various foods. This is promoted by modelling and discussion rather than by imposition. Students are not encouraged to bring their own packed lunches to school. Students who wish to bring in their own packed lunch must have permission from their Head of Section. Parents will still need to pay the relevant school fees for the school food.
FS/KS1 children receive two morning snacks and lunch. The remainder of the students receive a morning snack and mid-day lunch.
