Effect of Dairy on Cognitive Performance in Children

Summary

The purpose of this study is to determine the effects of dairy consumption on short-term cognitive performance, subjective mood and emotions, and glycemic response in healthy children aged 9 - 14 years. The investigators hypothesize that the consumption of dairy products as a mid-morning snack will improve mood and cognitive performance in children. Furthermore, the investigators hypothesize that all dairy products consumed as a mid-morning snack will imbue more benefits on mood and cognitive performance over 2-hours compared to fruit juice or snack skipping.
