Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
A total of 116 participants (n=58/site) with prediabetes (hemoglobin A1c ≥6.0 \& \<7.0 and no glucose-lowering medications) and body-mass index (BMI) 18-40 will be recruited for a 12-week clinical trial to determine the effect of eating 2 items containing functional ingredients daily compared to 2 similar items lacking the functional ingredients. Study foods provided are to be incorporated into participant's usual diet.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
If the foods prove beneficial for managing blood glucose levels, the publication of results in scientific journals and in lay documents will increase awareness and provide important information of the health benefits of these products for consumers, health professionals and the food industry. It will also help individuals who may be able to manage their illnesses in a healthful non-pharmaceutical nutritional approach and who may benefit from physician-prescribed nutritional counseling with a focus on foods known to improve certain disease biomarkers. At this time these approaches lack practicality and direct application to individuals who are interested in adopting a new dietary regime capable of disease prevention.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Functional Ingredient Group
Participants will be provided with a mix of 6 study products to use over the 12 week trial (2 per day). These will be a) oatmeal, b) pancake mix, c) chocolate crunch bar, d) cranberry nut bar, e) anytime sprinkle, and f) smoothie mix. The food items will contain a standardized amount of functional ingredients.

Control Ingredient Group
The control group will receive a comparable set of food items that contain an equivalent amount of calories per portion but without the added functional ingredients.
