Flintstone Foods 1

This exploratory study is designed to compare the gastric layering and rates of emptying and by inference rates of digestion of a Palaeolithic inspired meal and a reference meal. Two types of meals, one high in fruit and vegetables will be used, and one based on WHO nutritional guidelines. Previous data suggests that the former meal releases nutrients more slowly than the latter. On each of two study days, a total of 11 MRI scans will be taken, 1 baseline and 10 post meal, to assess gastric layering and emptying. Participants will also be asked to complete a questionnaire at predetermined times to assess feelings of satiation.
