Description of intervention(s) / exposure

Summary
Brief summary
The study will evaluate the effects of different sugars on the release of the incretin hormone GLP-1 from the small intestine, and how this affects the gastric emptying of, and glycaemic response to, a subsequent meal, in both healthy subjects and patients with type 2 diabetes.
