Other | Post-prandial serum insulin | Post-prandial serum insulin Area under versus time curves | Total Area under the insulin versus time Curve 0-2 hours after the intake. | |
Other | Glucose in urine | Glucose in urine was measured using dipsticks with a detection limit of 2.28 mmol/L | Subjects were asked to empty their bladder before study product intake (-20 minutes) and again before leaving the site ( 450 minutes). In these two samples and in all additional urine samples voided while subjects were on site, glucose was analyzed | |
Primary | Post-prandial blood glucose | Glucose concentration in venous plasma | Positive incremental Area under the glucose versus time Curve between 0 (before) and 2 hours. | |
Secondary | Breath hydrogen excretion | Hydrogen gas in exhaled breath. When a subject produced 10 ppm hydrogen or more above the basal breath hydrogen level the treatment was regarded as a "positive" | Fifteen minutes before (basal) and 65, 125, 185, 245, 305, 365 and 425 minutes after the ingestion of the test products | |
Secondary | Intestinal discomfort | An intestinal discomfort questionnaire was administered. The questionnaire asked whether subjects had experienced 1) flatulence, 2) nausea, 3) bloating or 4) pain in the bowels. Percentage of "Yes" scores was calculated per discomfort. | Ten minutes before (baseline) and at 130, 250, 370 and 420 minutes after the ingestion of the test products. | |
Secondary | Stool consistency and number of stools | Stool consistency was evaluated by semi-quantitative Bristol scale (score between 1 = constipation and 7 = watery diarrhea). | 24 hours before study product intake, during 7 hour the test day and in the 17 hours after the test day (telephone interview). |
