Area of Science:

  • Pediatric Nutrition
  • Educational Psychology
  • Public Health

Background:

  • Limited research exists on the link between children's diet quality and academic performance.
  • This study investigates the association between overall diet quality and academic outcomes in children.

Purpose of the Study:

  • To examine the relationship between diet quality and academic performance in grade 5 students.
  • To identify specific dietary factors influencing academic achievement.

Main Methods:

  • Surveyed 5200 grade 5 students and parents in Nova Scotia, Canada.
  • Utilized the Diet Quality Index-International to assess diet quality.
  • Employed multilevel regression to analyze the association with literacy assessment results, controlling for sociodemographic factors.

Main Results:

  • A significant association was found between decreased diet quality and poorer academic performance.
  • Girls, children from socioeconomically advantaged families, and those in better schools/neighborhoods performed better.
  • Specific dietary factors were identified as contributing to this association.

Conclusions:

  • Diet quality is demonstrably associated with academic performance in children.
  • Findings support the implementation of school nutrition programs to enhance diet quality and academic success.
  • Improving student nutrition can lead to better academic outcomes and long-term health benefits.
