Primary outcomes

  1. Change of Satiety

    Time frame: 0, 20, 40, 60, 90 and 120 minutes post snack consumption

    Hunger feeling (appetite) will be examined using visual analog scale (0-10): 0 least and 10 greatest

  2. Change of glucose level

    Time frame: 0 and 40 minutes post snack consumption

    Blood will be collected by finger pricks and change of glucose level will be examined.

  3. Change of insulin level

    Time frame: 0 and 40 minutes post snack consumption

    Blood will be collected by finger pricks and change of insulin level will be examined

  4. Change of anxiety feeling

    Time frame: 0 and 40 minutes post snack consumption

    Anxiety feeling will examined using STAI (Spielberger Stasumte-Trait Anxiety Inventory) questionnaire (1-4): 1 least and 4 greatest, total summed score will be used.

  5. Change of antioxidant level
