摘要：

The National School Lunch Program's effect on children's diets has been extensively studied. Results have tended to be inconclusive regarding the effectiveness of the program. Utilizing more specific treatment groups, we find that participants in the National School Lunch Program do not consume a higher-quality diet at lunch than children choosing not to participate, even though the program is offered-but rather consume a higher quantity of foods while consuming similar amounts at other meals. Furthermore, children attending schools not participating in the National School Lunch Program have dietary outcomes that are not significantly different from program participants.
