Association of cheese and yogurt intake with sleep duration in preschool-aged children: a 6-month prospective cohort study

Our findings suggest that frequent cheese intake may reduce the risk of insufficient sleep in preschool-aged children, whereas yogurt shows no comparable association. These differential results underscore the need for product-specific analyses. Despite limitations in sample size and measurement, the study adds to evidence linking diet, microbiota, and sleep. Further research should clarify underlying mechanisms and guide actionable, child-appropriate dietary recommendations.
