Understanding Liver Fat Metabolism: Studies to Understand the Role of Dietary Sugars on Liver Fat Metabolism

The investigators will recruit men and women with no medical condition or relevant drug therapy that affects lipid, glucose or liver metabolism. Purpose and design: The investigators are asking the research question: "How does the amount and type of sugars consumed, such as those found in soft drinks, influence postprandial fatty acid and liver fat metabolism?" It is known that consuming fructose by itself or with glucose can increase plasma triglyceride concentrations and liver fat amounts but it remains unclear how this happens. To address this research question investigators want to undertake detail physiological studies, in a randomised cross-over study where individuals will be studied twice after the consumption of a single test meal that will contain different amounts of glucose and fructose with the same amount of dietary fat.
