Evidence suggests that the effect of fasting on performance is not
uniform, but it is dependent on the basal nutritional status of the
subject. Breakfast consumption has a short-term effect in improving
selected learning skills, especially work memory. School breakfast
programmes have a positive effect on the nutritional status of
children, on school attendance and probably on dropout rates. The
effect of breakfast consumption on school performance depends on the
interaction between the programme, student characteristics
(malnutrition) and school organisation. Unless the school setting
guarantees a minimum quality standard, the benefits of breakfast
consumption will not be evident in performance in complex areas like
language or maths.
