We believe that the approach used in this study can help generate new knowledge beyond that already reported for the consumption of green kiwifruit. In this single-blinded, negative-controlled, randomised, parallel study, we aim to find differences in abdominal comfort between individuals with FC or IBS-C by ingesting either two Green Kiwifruit daily or Maltodextrin over the course of 4 weeks. The trial will be a maximum of up to 9 weeks in total. We hypothesise that the habitual consumption of two green kiwifruit will improve abdominal pain as measured by the GSRS ratings, other gut symptoms, bowel habits, fatigue, anxiety, depression, and total intestinal transit in individuals with FC and IBS-C. Additionally, we hope to find differences in the microbiome and metabolome in individuals consuming kiwifruit compared to control.
