Brief Summary:
This study aims at investigating the impact of colonic fermentation of intrinsic indigestible carbohydrates in cereal whole kernels after three days consumption, on metabolic variables and cognition. The study is performed in healthy, normal to slightly over-weight test subjects.

Arm Intervention/treatment
Experimental: indigestible carbohydrates
test meal: indigestible carbohydrates
Other: test meal
Experimental: reference
reference meal: no indigestible carbohydrates
Other: reference meal

Primary Outcome Measures :
  1. Area under the plasma concentration versus time curve (AUC) of the test meal [ Time Frame: Post-prandially after breakfast, 0-150 min ]
    The differences in AUC between different risk markers, assessed in plasma or serum,after intake of the test meal in comparison to the reference meal is measured. Example of variables measured are glucose, insulin, appetite hormones, inflammatory markers, markers of colonic fermentation.

Secondary Outcome Measures :
  1. Cognitive performance [ Time Frame: Post-prandially after breakfast, 0-210 min ]
    The cognitive performance of the test subjects is measured to investigate work memory and specific attention.

  2. Subjective satiety [ Time Frame: post-prandially after breakfast, 0-150 min ]
    The subjective sensation of satiety, hunger and desire to eat is measured using a questionnaire.
