RESUMO
It is hypothesized that giving children a daily breakfast at school may improve their scholastic achievement through several mechanisms: increasing the time spent in school, improving certain cognitive functions and attention to tasks, and, perhaps indirectly, improving nutritional status. Two Jamaican studies showed that providing breakfast to students at school improved some cognitive functions, particularly in undernourished children. However, changes in classroom behavior varied depending on the quality of ths school. Children in better-organised schools concentrated on tasks for longer periods and made fewer undesirable movements, whereas in poorly organized schools the children's behavior deteriorated. Studies to date have provided insufficient evidence to determine whether children's long-term scholastic achievement is imporved by eating breakfast daily. Well-designed, randomized, controlled. long-term trials are essential for determining public policy on the implementation of schools feeding programme(AU)
