Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine glycemic response of four different meals containing either whole green peas, whole lentils, powdered green peas, or powdered lentils in comparison to Glucola. Participants are adults with type 2 diabetes mellitus or metabolic syndrome.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The 5 test treatments (Glucola, whole green peas, green pea flour, whole lentils, and lentil flour) will be administered randomly over five weeks. The test Participants will be required to consume the entire test treatment meal in 12 minutes while being observed. Venous blood samples will be collected for blood glucose and insulin levels at time 0 (fasting) and at 30, 60, 90, 120, and 180 minutes post-treatment (timing of the post-treatment blood draws started at time 0 \[post-treatment\], which is when the participant finishes consuming the treatment meal). During the first visit blood was drawn for a lipid panel and HbA1C values. Thyroid stimulating hormone (TSH) and complete blood count (CBC) values were analyzed during the second visit, and vitamin D levels analyzed during the final visit. Blood analysis was completed by a reputable biomarker diagnostics laboratory, Quest Diagnostics. Anthropometric measures such as weight, height, waist circumference, and blood pressure were collected at screening and at the start of each test day. Thirteen hours before testing, participants consumed a standardized frozen meal to reduce the potential variation in glycemic responses on test day due to varying pre-evening dietary intakes. This control meal was selected by each participant before the start of the study. Each participant was provided the same frozen meal every time, since the subjects serve as their own controls. The day before test day, participants completed a 24 hour food recall, satiety, and gastrointestinal questionnaires. The morning of each test day participants completed the International Physical Activity Questionnaire (IPAQ), satiety, and gastrointestinal questionnaires. Test meal and blood glucose results at the 5 test points were entered into SPSS statistical software (V. 25) for data cleaning and analysis. Physical activity and the 24 hour dietary recall data were used to classify individuals on activity and dietary quality. Satiety responses were compared against each of the 5 test meals for each participant as well as the gastrointestinal responses using SPSS.
