BACKGROUND: Dessert compositions may conform to diabetic diet when it contains low sugar or artificial sweetener to replace sugar. However, it is still questionable whether glycemic control in type 2 diabetes patients is improved by the use of diet-conforming dessert compositions. OBJECTIVE: To compare, in type 2 diabetes patients, the glycemic, insulin, and C-peptide responses to seven modified dessert compositions for diabetics (D-dessert) with the response to seven similar desserts of non-modified composition, used as control desserts (C-dessert). METHODS: Seventy type 2 diabetes patients were allocated to seven groups of ten. On three occasions, each patient received either the meal which consisted of bread and cheese, or the meal and D-dessert, or the meal and the respective C-dessert. Differences in postprandial glucose, insulin, and C-peptide were evaluated using analysis of repeated measures at 0, 30, 60, 90, and 120 min after consumption. RESULTS: D-cake and D-pastry cream resulted in lower glucose levels (8.81 ± 0.32 mmol/l and 8.67 ± 0.36 mmol/l, respectively) and Dstrawberry jelly in lower insulin levels (16.46 ± 2.66 µU/ml) than the respective C-desserts (9.99 ± 0.32 mmol/l for Ccake, 9.28 ± 0.36 mmol/l for C-pastry cream, and 27.42 ± 2.66 µU/ml for C-strawberry jelly) (p < 0.05). Compared with the meal, D-cake did not increase glucose or insulin levels (p > 0.05), while C-cake did (p < 0.05). D-pastry cream increased glucose to a lesser extent than C-pastry cream (p < 0.05). Similar effects were reported for D-milk dessert, Dmillefeuille, and D-chocolate on glucose, insulin, and Cpeptide at specific timepoints. D-crème caramel showed no effect. CONCLUSIONS: Some desserts formulated with sugar substitutes and soluble fiber may have a favorable effect on postprandial levels of glucose, insulin, and C-peptide in type 2 diabetic patients.
