Manipulating the physical form of food may have an impact on gastrointestinal function and satiety. We hypothesised that feeding to healthy volunteers a solid/liquid meal blended to a soup: (a) gastric volumes would fall more slowly (b) satiety would be enhanced (c) the CCK duodenal response (as inferred from gallbladder contraction) would be enhanced and (d) the small bowel secretion would be greater. We were able to test these hypotheses by carrying out carried one satiety study in quiet controlled conditions and one mechanistic study using serial, functional gastrointestinal MRI.
