Interaction Between Dairy and Gut Hormone Response on Cognitive Performance in Children.

The purpose of this study is to investigate the short-term effects of milk and yogurt of varying fat and protein content on cognitive performance in healthy children aged 9 - 14 years; and to provide insight into mechanisms by which dairy consumption may affect cognitive performance through gastrointestinal (GI) hormone responses. The investigators hypothesize that the consumption of dairy products, specifically their protein and fat components, will improve cognitive performance via its interaction with the gut-brain axis in children. Furthermore, the investigators hypothesize that all milk and yogurt products will enhance cognitive performance over 120- mins compared to snack skipping through its interaction with GI hormones, with a greater effect in higher fat containing milk and yogurt products.
