Almond Butter and Fasting Glucose

Clinical Trial ID: NCT03826472


A two-period randomized crossover study will be conducted to determine the effect of almond butter as an evening snack on fasting blood glucose in adults with type 2 diabetes, not taking insulin.

Control of fasting blood glucose is a challenge for many individuals with diabetes. Researchers want to better understand how a nighttime snack can affect morning fasting blood glucose. A two-period randomized crossover trial will be conducted. Participants will be randomized to receive each treatment for 1 week. During the almond butter treatment, participants will consume 2 tbsp of almond butter per day as an evening snack. The control treatments will be a no-snack control. Fasting blood glucose, as well as glucose trends, will be measured using Continuous Glucose Monitor (CGM). Participants will also be asked to take simple cognitive tests on a study-provided smartphone each day of the study and report their daily food intake and physical activity.
