The effect of sugar cereal with and without a mixed meal on glycemic response in children with diabetes.

The effect of sucrose consumption on glycemic control in children with insulin-dependent diabetes mellitus is unclear. Eight young subjects, 7-16 years of age, with a duration of diabetes of 2-8 years participated in this study. All subjects consumed four different breakfasts--oatmeal (OM) alone, oatmeal-sucrose (OMS), oatmeal-protein (OMP), and oatmeal with protein and sucrose (OMPS)--on four different days. Addition of sucrose resulted in a slightly greater area under the tolerance curve in 50% of the subjects; however, in 38% of subjects, the area decreased. The peak glucose level was lowest for OM, but there was no statistical difference in the peak levels of the four test meals. The most significant effect on glucose response was a delay in the peak time when protein was added to the meals. Peak times for OM and OMS (mean of 38 min) when fed alone were significantly (p less than 0.05, ANOVA) shorter when compared to the peak time for OMP and OMPS (mean of 54 min). The average recovery time for OMP was longest. Other indices (tolerance index and change of rise in blood glucose) measured were not significantly different among the test meals. This study demonstrates that adding limited sucrose to OM cereal has little effect on the blood glucose response in children with diabetes. Addition of protein and fat clearly delays the glycemic response.
