Healthy school meals are usually discussed in terms of nutrition. A new study suggests they may also belong in a broader conversation about how schools support learning.
Published in PLOS One, the study found that children in Dutch primary schools participating in a program that combined healthy lunches with more physical activity performed better on math tests over time than children in comparison schools. The findings suggest that a healthier school day, including both food and movement, may support children’s ability to learn.
The study analyzed the Healthy Primary School of the Future program, a school-based effort in the Netherlands designed to create a healthier daily environment for children. The full version of the program included healthy lunches and additional physical activity during the school day.
That combination matters. Children’s ability to focus, learn and participate in class can be shaped by many parts of their day, including whether they have enough food, what kinds of foods are available, how much they move and how structured their school routine feels. This study looked at the effect of a whole-school program, not a single meal or nutrient.
Researchers compared educational outcomes among children exposed to the program and children in control schools. According to the analysis, children in schools implementing the full program showed significantly better math performance after multiple years of exposure.
The finding is likely to interest parents and educators because school meals are often discussed mainly in terms of nutrition, hunger or weight. Those are important, but the study adds another question: Could healthier school environments also support academic performance?
The answer from this study is promising but cautious. Math scores improved in the schools with the full program, but the research does not show exactly which part of the program mattered most. Healthy lunches, more physical activity, school structure, student engagement or other school-level differences could all have contributed.
The study also took place in the Netherlands, where school food systems, daily schedules and education policies differ from those in the United States. That does not make the findings irrelevant for American readers, but it does mean they should not be treated as a simple blueprint for every school.
Still, the larger idea is easy to understand. Children spend much of their day at school, and schools shape the conditions under which children learn. A child who has access to a balanced lunch and regular movement may be better supported than one trying to learn through hunger, fatigue or long stretches of sitting.
The study also points to a practical tension. Parents are often expected to manage children’s nutrition one lunchbox at a time, but children’s eating patterns are also shaped by the systems around them. When schools make healthy food and physical activity part of the regular day, the burden does not fall entirely on individual families.
The education data source used in the study was supported by the Kennisas project Educatieve Agenda Limburg, the Provincial Government of Limburg, Maastricht University and primary and secondary schools in Limburg. The Healthy Primary School of the Future project was supported by Limburg provincial authorities, Maastricht University and FrieslandCampina, a dairy company.
