This metadata record and it’s attached files make statements about the kinds of data collected as part of this research, and set out policies for governance of that data, now and in the future.Description: The Kiwifruit Ingestion to Normalise Gut Symptoms (KINGS) study was launched to understand more about the clinical, psychological, biological, and dietary changes in individuals with Functional Constipation (FC) or Constipation-Predominant Irritable Bowel Syndrome (IBS/C). We believe that the approach used in this study can help generate new knowledge beyond that already reported for the consumption of green kiwifruit. The Auckland KINGS Gastric is a second locality for the KINGS in the Christchurch IBS cohort (ACTRN12621000621819), with site-specific study design and secondary outcomes. In this single arm, open-label, intervention study, we aim to assess the impact of habitual consumption of two Green Kiwifruit daily for 4 weeks on abdominal pain, bowel habits and other gastrointestinal symptoms in individuals with FC/IBS-C; and to evaluate the effects of habitual consumption of Green Kiwifruit on digestive function and biomarkers of these physiological effects. Additionally, we hope to investigate the influence of the two Green Kiwifruit intervention on the microbiome and metabolome, and to compare differences between individuals with constipation and healthy controls. The trial will be a maximum of up to 8 weeks in total.
