Scientific title
Study objectives	Low glycemic index diets will improve glycemic control in type two diabetic subjects treated with oral agents.
Ethics approval(s)	Approval received from: 1. St. Michael's Hospital REB (ref: 04-021c) 2. University of Toronto REB (ref: 17914) As of 20/08/2007: The sample size was approved to be increased to 200 subjects by St. Michael's Hospital Ethics Board on 31 October 2006 (REB#04-021).
Health condition(s) or problem(s) studied	Type two Diabetes
Intervention	Control: Advice to consume a high cereal fibre, whole grain, normal Glycemic Index (GI) diet (mean GI = 80). Test: Advice to consume a low glycemic index diet (mean GI less than 70) based on differences in the particle size and nature of the study foods but with similar fibre content to the 'control diet'. For further information, please contact the principal investigator Dr David Jenkins or the principal co-investigator Dr Cyril Kendall at the address listed below.
Intervention type	Other
Primary outcome measure	Treatment difference in the change in HbA1c accross treatments.
Secondary outcome measures	1. Fasting blood glucose 2. Fasting insulin 3. High sensitivity C-Reactive Protein (hs-CRP) 4. Oxidized Low Density Lipoprotein (LDL) 5. LDL particle size 6. High Density Lipoprotein (HDL) 7. Change in body weight or oral hypoglycemic agents
