Food that comes from all over the world. Nutrition education will not only be that which takes place in the classroom but the practices throughout the school that relate to food. Nutrition standards for school meals no longer apply. School tuck shops make much needed extra income. The governors, with the headteacher, will need to think about the whole school policy on such matters.
Education is a powerful weapon.
Young children need to understand the importance of food and nutrition to their health and wellbeing. I would suggest that a positive approach is used. Encourage a wide variety of food. It is excess of requirements that is not good. I suppose alcohol is a good example for adults.
