The goal of this clinical trial is to test the effects of wild rice and wild rice blends compared to other rice on glycemic control and evaluating factors that influence glycemic response to wild rice in healthy individuals. The main questions aim to answer:
Participants will:
This study will be a crossover randomized trial consisting of 5 sessions. The wild rice products will be provided by the Myera group.
Participants will fast and arrive at the Richardson Centre for Food Technology and Research (RCFTR) between 7am - 11am on the session day. They will be provided either of the study treatments based on randomization sequence. Baseline blood glucose (0 min) will be measured twice via finger stick blood sample right before their first bite of the study product, and at 15, 30, 45, 60, 90 and 120 mins after baseline in duplicate. VAS will be completed following consumption of the treatments to measure palatability and subjective appetite at baseline (0 min), and at 15, 30, 45, 60, 90, and 120 minute time points.
The primary objective is to test the effects of wild rice and wild rice blends compared to other rice on glycemic control and evaluating factors that influence glycemic response to wild rice in humans performed via the finger stick blood glucose that will be measured throughout each session as outlined above. Secondly, to test whether wild rice glycemic response is affected based on cooking method.
