In the Child Nutrition Act of 1966 it was stated that educational progress was an objective of the United States School Feeding programs. In spite of this fact no serious attempt has ever been made to evaluate whether this objective has been met; the few evaluations that have been conducted lack scientific rigor. As a whole the studies fail to provide a strong basis from which to make valid inferences regarding the long-term effects of the feeding program on school achievement and adaptation. Studies that have focused on the short-term effects of hunger or morning feeding suggest that the provision of breakfast may both benefit the student emotionally and enhance his capacity to work on school type tasks.
1966年的《儿童营养法》规定,教育进步是美国学校供餐计划的一个目标。尽管如此,从未有人认真尝试评估这一目标是否实现;已进行的少数评估缺乏科学严谨性。总体而言,这些研究未能提供一个有力的依据,以便就供餐计划对学业成绩和适应能力的长期影响做出有效的推断。关注饥饿或早餐供应短期影响的研究表明,提供早餐可能对学生的情绪有益,并提高其完成学校类型任务的能力。
