Utilizing GI: Exploring an Optimum Glycaemic Profile for Cognitive Function Across the Day

Utilizing GI: Exploring an Optimum Glycaemic Profile for Cognitive Function Across the Day in Healthy Individuals

This study provides participants with two diets that vary in their glycaemic index values (low vs. high), whilst also measuring cognitive performance and mood.

Therefore, the current study introduces cognitive testing into study procedures. Participants will consume the favourable and unfavourable conditions (each containing three meals) on separate days following a crossover, randomised, couterbalanced design. The primary dependent variable is cognitive function, whilst secondary measures include glucose and mood. It is hypothesised that the favourable meal profile will be associated with cognitive and physiological benefits relative to the unfavourable meal profile.
