Increased dietary fructose ingestion resulted in significantly accelerated half-emptying time of a fructose solution ( mean = 48 , SD = 6 versus 58 , SD = 14 min control ; P = 0.037 ) , whereas the emptying of a glucose solution remained unchanged ( mean = 85 , SD = 31 versus 78 , SD = 27 min control ; P = 0.273 ) .
