A study looking into the effects of green kiwifruit on sleep quality and the sleep-wake cycle in healthy males has received funding of $31,800 over twelve months by the High-Value Nutrition Ko Ngā Kai Whai Painga National Science Challenge. The study builds on previous research, which showed that sleep quality can improve with the daily consumption of two Aotearoa New Zealand green kiwifruit for four weeks.
The study is being conducted by Riddet Institute-funded PhD candidate Alex Kanon, under the supervision of Dr Sharon Henare, Ngāti Whātua, Ngā Puhi, Senior Lecturer in the College of Health at Massey University. Zespri International Limited is providing contributions of fresh green kiwifruit.
The research will look into whether the consumption of fresh green kiwifruit (without skin) will improve sleep quality outcomes and increase the urinary concentration of metabolites central in the regulation of sleep-wake cycles. It will also investigate whether these effects will be enhanced using a freeze-dried form of kiwifruit that includes the skin of the fruit.
