Each participant will undergo three experimental trials in a randomized, crossover research design. On each study day, participants will consume a test drink containing standardised amounts of carbohydrate and fat followed by collection of blood and breath samples to assess metabolic responses during the 6 hour postprandial period. Trials will be identical except for the type of carbohydrate contained within the test drink: 1) maltodextrin (glucose polymer), 2) lactose (galactose-glucose disaccharide) and 3) sucrose (fructose-glucose disaccharide).
This study aims to determine to what extent ingestion of free sugars influence postprandial triglyceridaemia in men and women.
