• Status: Completed
• Phase: N/A

Summary

This study provided 24 healthy subjects with two diets that varied in their glycaemic index values. One condition was a low GI diet, whilst the other was a high GI diet. Glucose concentrations and mood were measured throughout each test day.

Detailed description

Therefore, the aim of this study is to feed to participants meals which differing in their glycaemic index across the course of a day, and thus produce different glycaemic responses. The outcome variables will be blood glucose levels and subjective mood. The purpose of this study is to identify the appropriate times (according to glycaemic response) at which cognitive functioning should be tested. Importantly, this study is also the first step to characterizing glycaemic and cognitive profiles associated with food consumption over a whole day (breakfast, lunch, snack) rather than just one meal (e.g. breakfast), ranging from the most favourable (stable glucose regulation) to the least favourable (variability; many peaks and troughs).

Conditions

• Mood
• Diet Modification
• Glucose, Low Blood
• Glucose, High Blood

Interventions

Type	Name	Description
DIETARY_SUPPLEMENT	Low Glycaemic Diet	This intervention consisted of three low GI meals.
DIETARY_SUPPLEMENT	High Glycaemic Diet	This intervention consisted of three meals, all with a high GI value.
