Eating whole SunGold kiwifruits, both with and without skin, can significantly decrease gut inflammation and alleviate constipation for both healthy people and those with irritable bowel syndrome.
In the 16-week cross-over study, 38 participants (both healthy and those with Irritable Bowel Syndrome-Constipation) were randomly assigned to consume either three whole SunGold kiwifruits without the skin or three whole kiwifruits with the skin for periods of four weeks, with a length of four weeks between each intervention as a washout period.
Following the intervention, it was observed that there was a significant reduction in pro-inflammatory cytokines (specifically TNF-α) for both the healthy participants and those with Irritable Bowel Syndrome-Constipation when whole kiwifruits, including the skin, were consumed. Furthermore, similar results were witnessed for the healthy individuals upon consumption of whole kiwifruits without their skin. The consumption of kiwifruit – including its skin – also increased bowel frequency and led to significant reductions in the gastrointestinal symptom rating scale for constipation and Irritable Bowel Syndrome-related pain scores for both participant groups. Results indicate that the skin of the SunGold kiwifruit may have beneficial effects on gastrointestinal health that are not derived from merely consuming the fruit's flesh.
