Feasiblity of The G.I. guide to increase knowledge about the glycaemic index in practice

Background Research findings support the application of the glycaemic index concept in the dietary treatment of diabetes. However, it is still unclear how to use this concept in general practice. The G.I. guide was accordingly developed to be used as an educational tool when introducing the glycaemic index in practice.
Methods A sample of 21 professionals involved with the treatment of diabetes (expert population), and 18 individuals with diabetes (lay population), were included in a pilot study to determine the feasibility of The G.I. guide to increase knowledge about the glycaemic index in practice. All participants were asked to complete a knowledge questionnaire on the glycaemic index before and directly after meeting and discussing The G.I. guide.
Results The mean change in knowledge about the glycaemic index before and after being exposed to The G.I. guide was highly significant in both the expert ( P  < 0.0001) and the lay group ( P  < 0.0001). The G.I. guide did not change lay or expert participants' opinions about healthy eating guidelines.
Conclusion The G.I. guide was effective in increasing knowledge and raising interest about the glycaemic index in practice.
