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.

Detailed description

A randomized within-subject repeated measures experiment will be used to study the effects of dairy product consumption on cognitive performance, subjective mood and emotions, and blood glucose in healthy 9 - 14 year old children. Participants will consume, in a random order on separate mornings, one of the five treatments: (a) milk, (b) yogurt, (c) cheese, (d) fruit juice, or (e) snack skipping. Subjective mood/emotions and cognitive domains (learning and memory, spatial working memory, attention, processing speed, and executive function) will be assessed at baseline (0-min), and 15-, 30-, 60-, and 120-min following treatment consumption. Blood glucose measurements will be collected using the Freestyle Libre 2 continuous glucose monitoring system.
