5. Study Description
Brief Summary
To evaluate the effect of onyx sorghum on blood glucose levels in patients with type 2 diabetes (T2DM).
Detailed Description
The plan is to study 24 participants with T2DM, who are otherwise healthy. The study will be double-blinded and randomized. Participants will first attend a screening visit (Visit #1) to determine eligibility. Then, eligible participants will be asked to wear a FreeStyle Libre Pro continuous glucose monitor (CGM) for up to 14 days (Visit #2). After this 14-day CGM session, participants will be randomly assigned (1:1) to one of two groups that will receive: 1) food products containing onyx sorghum (Onyx Group) or 2) food products with wheat flour (Control Group). The diet intervention will last a total of 28 days. Participants will have weekly visits to pick up food and bi-weekly blood draws (no more than 20mL at each visit). They will also be asked to wear the CGM throughout the diet intervention and will record their food intake in a daily food diary to confirm that the diet intervention is being followed.

Arm Type
Active Comparator
Arm Description
Patients with T2DM will receive food products with wheat flour.
Intervention Type
Dietary Supplement
Intervention Name(s)
onyx sorghum
Intervention Description
The diet intervention will last a total of 28 days. Per the American Heart Association (AHA) and American Diabetes Association (ADA) recommendations, the daily diet plan will consist of 50-55% carbohydrate, 15-20% protein, and 25-30% fat. In the Onyx Group, 25% of carbohydrate will come from the onyx sorghum, and at least three foods per day (including cereals, bread, muffins, pasta, and smoothie boosters) will contain this.
