Trial results investigating the effects of low-calorie sweetened beverage restriction in youth with Type 1 Diabetes were posted on ClinicalTrials.gov on 2025-08-26. The study, involving 62 participants, reported a mean glycemic variability of 2.00% in the restriction group compared to 3.91% in the control group.
Background
Type 1 Diabetes (T1D) is a chronic autoimmune condition characterized by the pancreas's inability to produce insulin, requiring lifelong insulin therapy. Managing T1D involves careful monitoring of blood glucose levels, diet, and lifestyle to prevent complications such as cardiovascular disease, kidney disease, and nerve damage. The role of low-calorie sweeteners (LCS) in the diet of individuals with T1D, particularly youth, has been an area of interest. This study aimed to investigate whether LCS are helpful or harmful for preventing diabetes complications among children with Type 1 Diabetes.
Trial design
This completed study, designated as Phase NA, enrolled 62 participants with Type 1 Diabetes. The trial investigated the effects of restricting low-calorie sweetened beverages compared to usual consumption in youth to assess their impact on diabetes complications.
Key results
- Glycemic Variability:
- In the Low-calorie Sweetener Restriction group, the mean glycemic variability was 2.00% (Standard Deviation 2.59%).
- In the Usual Consumption/Control group, the mean glycemic variability was 3.91% (Standard Deviation 2.59%).
- Visceral Adiposity:
- For the Low-calorie Sweetener Restriction group, the mean visceral adiposity was 0.1% body fat (Standard Error 1.1% body fat).
- For the Usual Consumption/Control group, the mean visceral adiposity was 1.0% body fat (Standard Error 0.8% body fat).
- Change in Inflammatory Cytokines (TNF-alpha):
- In the Low-calorie Sweetener Restriction group, the mean change was 0.08 pg/mL (Standard Error 0.07 pg/mL).
- In the Usual Consumption/Control group, the mean change was -0.23 pg/mL (Standard Error 0.08 pg/mL).
What this means
The results suggest that restricting low-calorie sweetened beverages in youth with Type 1 Diabetes may be associated with reduced glycemic variability. The mean glycemic variability was lower in the restriction group compared to the control group. Regarding visceral adiposity, the restriction group showed a lower mean value, though the standard errors were notable in both groups. For inflammatory cytokines, specifically TNF-alpha, the restriction group showed a slight mean increase, while the control group showed a mean decrease. It is important to note that these are reported measurements, and the data provided does not include statistical analyses to determine the significance of these differences.
