Impact of Meal Composition and Alcohol Consumption on Postprandial Glycemic Control in Subjects With Type 1 Diabetes

Postprandial glucose control is a challenging issue in everyday diabetes care. Indeed, excessive postprandial glucose excursions are the major contributors to plasma glucose (PG) variability in subjects with type 1 diabetes (T1DM). In addition, the poor reproducibility of postprandial glucose response is burdensome for patients and healthcare professionals. To date, the majority of prandial insulin dosing algorithms for subjects with T1DM considers only the carbohydrate (CHO) content of the meal. However, there is evidence (although with a certain degree of heterogeneity) that meal composition significantly affects postprandial glucose control, contributing to glycemic variability. Moreover, despite the high prevalence of alcohol consumption among patients with T1DM (about 30%, similar to that of the general population), data regarding its effect on the postprandial period are very limited. This project will evaluate the effect of meal composition and alcohol consumption on postprandial glucose control in subjects with T1DM under intensive insulin treatment.
