Background: Low-glycemic index (GI) diet vs. high-GI diet improves glycemic control, but it is not clear whether a low-GI diet is superior to an optimized mixed diet (OMD).
Methods: This was a 12-week parallel-group pilot-trial including 17 children with type 1 diabetes. A separate dietary education into the allocated diet (OMD vs. low-GI) was performed. Nutrition was recorded by means of a three-day dietary record.
Objectives: The primary objective was to determine the macro- and micronutrient composition of the different diets, the secondary objective was to determine the short-term effect on HbA1c levels.
Results: In the low-GI group carbohydrate intake decreased, fat intake increased by trend. In the OMD group fat and energy intake decreased. No changes of HbA1c levels between the groups were observed.
Conclusion: OMD could have positive effects in overweight and obese diabetic children, since a reduction in fat and energy intake can be achieved. The findings of this pilot-trial suggest that OMD could be superior to a low-GI diet.
