Objective: To compare the postprandial plasma glucose level after diabetic specific formula (DSF) and standard formula (SF) administration in type 2 diabetic patients.
Material and method: Thirty type 2 diabetic patients were included in the present randomized, controlled, double-blind, cross-over study. Subjects received DSF and isocaloric SF as a bolus administration of 400 mL while continuing their anti-diabetic medications. Venous blood samples were collected and analyzed to assess plasma glucose levels at pre- and at 30, 60, 90, 120, and 180 min post-administration of the formulas.
Results: Postprandial glucose profiles were significantly lower with DSF compared to SF administration determined as a mean glucose concentration at 2-hour post-administration. The glucose area under the curve (AUC) after DSF consumption was 33% lower than the AUC after SF consumption, p < 0.001.
Conclusion: Use of DSF resulted in a significantly lower postprandial rise in plasma glucose concentrations than using SF. It should be the preferred option in diabetic patients who need nutritional support.
