Incremental serum insulin response curve during the two-hour postprandial period. The change in serum insulin concentration was calculated by deducting the basal level from the insulin level measured after intake of the test drinks and was represented as delta serum insulin. Median values were plotted. Median values with different letters denote significant differences between Beetroot and Bilberry, and between Beetroot and Rose hip (P < 0.05)
