摘要：We aimed to assess the impact of consuming two Zespri Hayward green kiwifruit a day on 11 healthy women subjects over a period of 4 consecutive weeks. We analyzed the effects of kiwifruit consumption on intestinal, abdominal, and bowel movement related discomfort, bowel movement frequency, peripheral blood flow, skin health, and autonomic nervous system activity. This study was a randomized control trial, consisting of a four-week intervention period. Participants were divided to ensure equal age distributions and then randomly placed into two intervention groups: a kiwifruit consumption group (n = 11) and a control group (no kiwifruit consumption) (n = 5). The kiwifruit consumption group was instructed to consume two kiwifruit a day during the 4-week intervention period, while subjects in the control group were instructed not to consume kiwifruit for the duration of the study. Besides a restriction from eating yogurt and other fruits, subjects were requested to eat their meals as per usual. The results of this study showed a significant decrease in intestinal, abdominal, and bowel movement discomfort, and a significant increase in bowel movement frequency, at 4 weeks of kiwifruit consumption compared to before consumption. In addition, subjects in the kiwifruit consumption group experienced a significant increase in blood flow, particularly in the index and middle finger at 2 and 4 weeks of kiwifruit consumption. Furthermore, subjects in the kiwifruit consumption group experienced a significant increase in skin brightness at 4 weeks of kiwifruit consumption compared to before consumption. The results of this study suggest that kiwifruit appears to be a delicious and safe option for intestinal, abdominal, and bowel movement discomfort interventions for healthy women. In addition, kiwifruit may aid in increasing bowel movement frequency, peripheral blood flow, and brightness of skin among healthy women as well.
