Clinical Trial 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.


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).

Outcome

Type Measure Description Time frame Safety issue
Primary Change in Glycaemic profile across the day Change in blood glucose concentrations (mmol/L) Assessed at 0 (baseline), 15, 30, 45, 60, 90, 120 mins after each meal. With 3 meals in a day this totaled 21 assessment point for each day, giving 42 assessment points to compare overall. Data will be reported for the duration of this 3 year PhD award.
Secondary Mood (alertness, anxiety and contentment) measured by Bond & Lader (1974) Visual Analogue Scale The Bond & Lader VAS provides participants with 16 lines measuring 100mm each. At the ends of each line are two words opposite in meaning. For example, 'alert' and 'drowsy'. A participants marks on the line closer to the word they currently feel. The score from each line is out of 0 to 100. This was measured 6 times a day (every 90 minutes starting at 0 minutes/baseline), giving a total of 12 times. Each time last approximately 5 minutes, giving a total of 60 minutes overall. Data will be reported for the duration of this 3 year PhD award.
