Investigating the effectiveness of a novel starch in participants suffering a functional bowel disorder

Treatment interventions were dietary butyrylated high amylose maize starch (HAMSB) or low amylose maize starch (LAMS) which were consumed daily for 14 days, The starch supplement (HAMSB or placebo starch) consisted of two pre-packed 20 g sachets daily, one consumed in the morning and one in the evening. The supplements were consumed by mixing the starches into 250 mL reduced fat flavoured UHT milk, orange juice, water or foods by the participants. The first intervention was followed by a washout period of 4 weeks during which the participants did not consume any intervention and ate their normal diets. The washout was followed by 2 weeks consumption of the alternative intervention. All unused sachets were collected to monitor compliance, and SCFA levels will be measured in the stools of subjects to further verify compliance to the test starches.
