Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 38 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single (Participant)
Primary Purpose: Basic Science
Study Start Date : December 2013
Actual Primary Completion Date : February 2014
Actual Study Completion Date : February 2014

Arm Intervention/treatment
Placebo Comparator: Nutrient formulations without active ingredient
4 nutrient formulations without active ingredient and variable level of available placebo ingredient
Experimental: Nutrient formulation with active ingredien
4 nutrient formulations with increasing amount of active ingredient
Other: Dietary Intervention

Primary Outcome Measures :
  1. Incremental area under the blood glucose response curve [ Time Frame: 0-2 hours ]
    Glycemic response calculated from individual glucose measurements upon consumption of control and experimental test food products. The individual glucose measurements will be collected at baseline (prior to consumption of each test food product) and over a 2-hour period following the initiation of consumption of each test food product. The primary outcome is differential treatment-effect on the time-concentration glucose curve over the 2 hours post consumption of each test food product.

Secondary Outcome Measures :
  1. Rate of decline in blood glucose, peak blood glucose, peak insulin and adjusted time concentration area for insulin [ Time Frame: 0-2 hours ]
