Brief Summary:
This randomized, crossover study will include four clinic visits: one screening (day -7) and three test visits (days 0, 2, 4). The objective of this study is to assess the effects of dietary fiber-containing bars, at two doses of fiber, compared to a control product, on postprandial glucose and insulin responses in healthy adult men and women.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 40 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Intervention Model Description: Randomized, controlled, three-treatment, crossover trial with one screening/baseline visit and three test visits. At each testing visit, the study product (a bar) will be consumed with water.
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description: The study site will be provided pre-packaged, sealed containers of control (a bar with no fiber) and active study products (a bar with 10 grams of fiber and a bar with 20 grams of fiber). Each product container will be labeled with the lot number, expiration date, and blinded product code.

Arm Intervention/treatment
Placebo Comparator: Control bar (0 g fiber)
Each subject will be randomly assigned to consume a control sports bar-type product (0 grams of fiber) at one treatment visit.
Other: Control bar (0 g fiber)
Each subject will receive one control and two active treatments in a crossover design. The two active treatments are dietary fiber-containing bars at two doses of fiber. The control bar will not contain fiber.

Experimental: Medium-fiber bar
Each subject will be randomly assigned to consume sports bar-type product (containing 10 grams of fiber) at one treatment visit.
Other: Medium-fiber bar
Each subject will receive one control and two active treatments in a crossover design. The two active treatments are dietary fiber-containing bars at two doses of fiber. The control bar will not contain fiber.

Experimental: High-fiber bar
Each subject will be randomly assigned to consume sports bar-type product (containing 20 grams of fiber) at one treatment visit.
Other: High-fiber bar
Each subject will receive one control and two active treatments in a crossover design. The two active treatments are dietary fiber-containing bars at two doses of fiber. The control bar will not contain fiber.




Primary Outcome Measures :
  1. Change in the incremental area under the curve for capillary glucose. [ Time Frame: Up to 120 minutes - measured at each treatment visit ]
    Differences between the dietary fiber and control conditions following a breakfast meal tolerance test (MTT) completed at visits 2, 3, and 4 in the incremental AUC (iAUC) from pre-breakfast intake to 2 hours post breakfast intake for capillary glucose.


Secondary Outcome Measures :
  1. Change in the incremental area under the curve for venous glucose. [ Time Frame: Up to 120 minutes - measured at each treatment visit ]
    Differences between the dietary fiber and control conditions following a breakfast meal tolerance test (MTT) completed at visits 2, 3, and 4 in the incremental AUC (iAUC) from pre-breakfast intake to 2 hours post breakfast intake for venous glucose.

  2. Change in the incremental area under the curve for venous insulin. [ Time Frame: Differences between the dietary fiber and control conditions following a breakfast meal tolerance test (MTT) completed at visits 2, 3, and 4 in the incremental AUC (iAUC) from pre-breakfast intake to 2 hours post breakfast intake for venous glucose. ]
