Primary Outcome Measures :
  1. postprandial glycemia [ Time Frame: Acute study measuring postprandial glucose levels over 2 hours ]

Secondary Outcome Measures :
  1. The glucose reduction index potential (GRIP). The GRIP factor is the reduction in glycemic index units per gram of fiber. [ Time Frame: Data analysis ]
