Condition: Type 1 Diabetes (T1D) · Healthy Subjects · Sponsor: McGill University Health Centre/Research Institute of the McGill University Health Centre
The goal of this randomized crossover study is to test the prediction that consuming carbohydrates will affect insulin release differently depending on whether Non-Nutritive Sweeteners (NNSs) are consumed simultaneously. We aim to determine whether the predicted effects are associated with oral or post-oral sweet taste receptor signaling,. Our study will focus on patients diagnosed with type 1 diabetes (T1D) who are using an artificial pancreas (AP) system, as it allows us to monitor glucose and insulin levels over time. Participants will drink four different flavored beverages, some with sweet taste blockade and some without, in a counter-balanced order. They will then rate the sweetness of each beverage, and we will collect data from their AP system to monitor insulin and glucose level. To achieve this, we will conduct a pilot study to assess the effectiveness and best timing of sweet taste blockade in healthy individuals. Insights gained from the pilot study will inform the main study. Sucralose will be used as the NNS, maltodextrin as the carbohydrate, and Gymnema Sylvestre (GS) as the sweet taste receptor blocker.
