About

The goal of this acute double-blind cross over trial to test the effects of different wild rice cereal products compared to products currently on the market on glycaemic control. The main questions it aims to answer are:

1. What is the effect compared to products currently on the market on glycaemic control?
2. Is the wild rice product palatable?

Participants will:

• consent to attend 6 study visits being 2.5 hours each
• come to each visit fasted for at least 10-12 hours.
• complete a Motivation to Eat VAS following each blood measure

Full description

The study will consist of 2 acute double-blind cross-over trials and both trials investigate types of wild rice products tested against a white rice or white bread control. This is the second of the two trials and will be assessing four wild rice cereals against two control rice cereals.

Participants will fast and arrive at the RCFTR between 8 and 10:30 am on the session day. They will be provided either of the study treatment 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. The timer will be started when they take their first bite. VAS will be completed following consumption of the treatments to measure palatability.

The primary objective is to test the effects of different wild rice products compared to products currently on the market by 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.
