Background: Glycemia following pizza consumption is typically managed with a dual-wave insulin bolus. This study evaluated the effect of a simple bolus on glycemia following consumption of traditionally prepared pizzas with long (24 h) or short (8 h) dough fermentation periods. Research Design and Methods: On two separate evenings, children with type 1 diabetes (n = 38) receiving sensor-integrated pump therapy consumed traditionally prepared pizza with either short (pizza A) or long (pizza B) dough fermentation, and blood glucose was monitored over 11 h. A simple insulin bolus was administered 15 min preprandially. The carbohydrate and amino acid contents of the two types of pizza were analyzed by liquid chromatography and high-resolution mass spectrometry (LC-HRMS). Results: The mean (±standard deviation) time in range 3.9-10.0 mmol/L was 73.2% ± 23.2%, and 50.8% ± 26.7% of glucose measurements were within the range 3.9-7.8 mmol/L. However, during the 2 h after bolus administration, the mean time in range 3.9-7.8 mmol/L was significantly greater with pizza B than with pizza A (73.3% ± 31.5% vs. 51.8% ± 37.4%, respectively, P = 0.009), and the time in hyperglycemia (>10 mmol/L) was significantly shorter (mean percentage 6.1% ± 19.0% vs. 17.7% ± 29.8%, respectively, P = 0.019). LC-HRMS analysis showed that long fermentation was associated with a lower carbohydrate content in the pizza, and a higher amino acid content. Conclusions: Glycemia following consumption of traditionally prepared pizza can be managed using a simple bolus 15 min before eating. Glycemic control can be further improved by increasing the dough fermentation time. Study registration: NCT03748251, Clinicaltrials.gov.

Abstract

Background: Glycemia following pizza consumption is typically managed with a dual-wave insulin bolus. This study evaluated the effect of a simple bolus on glycemia following consumption of traditionally prepared pizzas with long (24 h) or short (8 h) dough fermentation periods. Research Design and Methods: On two separate evenings, children with type 1 diabetes (n = 38) receiving sensor-integrated pump therapy consumed traditionally prepared pizza with either short (pizza A) or long (pizza B) dough fermentation, and blood glucose was monitored over 11 h. A simple insulin bolus was administered 15 min preprandially. The carbohydrate and amino acid contents of the two types of pizza were analyzed by liquid chromatography and high-resolution mass spectrometry (LC-HRMS). Results: The mean (±standard deviation) time in range 3.9-10.0 mmol/L was 73.2% ± 23.2%, and 50.8% ± 26.7% of glucose measurements were within the range 3.9-7.8 mmol/L. However, during the 2 h after bolus administration, the mean time in range 3.9-7.8 mmol/L was significantly greater with pizza B than with pizza A (73.3% ± 31.5% vs. 51.8% ± 37.4%, respectively, P = 0.009), and the time in hyperglycemia (>10 mmol/L) was significantly shorter (mean percentage 6.1% ± 19.0% vs. 17.7% ± 29.8%, respectively, P = 0.019). LC-HRMS analysis showed that long fermentation was associated with a lower carbohydrate content in the pizza, and a higher amino acid content. Conclusions: Glycemia following consumption of traditionally prepared pizza can be managed using a simple bolus 15 min before eating. Glycemic control can be further improved by increasing the dough fermentation time. Study registration: NCT03748251, Clinicaltrials.gov.
