Desserts made with added soluble fiber (dextrin) and sucralose had positive effects on blood sugar and insulin levels in people with type 2 diabetes, finds study published in The Review of Diabetic Studies from the Society for Biomedical Diabetes Research
Researchers incorporated desserts after meals among 70 study participants with type 2 diabetes. The researchers outlined three significant findings:
Consumption of desserts made with sucralose and soluble fiber did not raise after-meal levels of glucose, insulin or C-peptide in comparison with meal consumption only (no dessert).
Desserts formulated with sucralose and soluble fiber may have a favorable effect on postprandial levels of glucose, insulin, and C-peptide in type 2 diabetic patients.
The study was conducted at the Diabetes Center of the General Hospital of Nikaea in Greater Athens, Greece and also included researchers from the Agricultural University of Athens. Researchers divided participants into seven groups of ten. On three occasions after an overnight fast, each participant received either a meal (bread and cheese); or a meal and dessert made with sucralose and dextrin; or a meal and dessert made with sugar. Differences in glucose, insulin, and C-peptide were evaluated at five different points in time after each meal. Among the desserts used in the study were cake, pastry cream, strawberry jelly, chocolate, and napoleons. (The full text of the study, including more about the methodology, is available here.)
Unlike sugar, sucralose is not broken down for energy. It is not a source of carbohydrate or glucose, and clinical studies have shown it has no effect on blood glucose levels, insulin secretion or blood levels, glycosylated hemoglobin levels (HbA1c), or blood glucose control.
"Even though this research was short term, this study adds to the growing body of scientific evidence suggesting that sucralose can play an important role in the management of diabetes," said Haley Curtis Stevens, Ph.D., President of the Calorie Control Council. In 2013, a separate study published in Diabetes Care, a journal of the American Diabetes Association, showed that consuming drinks containing sucralose have the same effect as drinking water on a one's sugar and insulin levels.
