This is a postprandial study with healthy volunteers. The glycemic and insulinemic responses elicited by meals containing either whole grain rye bread or white wheat bread as such or combined with margarine and ham and vegetable soup are compared. Blood glucose concentrations are monitored from finger prick blood samples collected before the meal and at 15, 30, 45, 60, 90 and 120 min. Venous samples for insulin concentrations are taken at time-points 0, 30 and 60 min.
