Effect of kiwifruit consumption on sleep quality in adults with sleep problems
Several works demonstrated the medicinal components of the kiwifruit, including antioxidants and serotonin that could help treat sleep disorders. In this free-living, self-controlled diet study by Lin et al. (2011), the authors investigated the impact of kiwifruit consumption on sleep patterns (onset, duration, and sleep quality). Study participants (n = 24, females = 22, age 20-55) ate two kiwifruits one hour before bedtime every night for four weeks and had their sleep evaluated using the Chinese version of the Pittsburgh Sleep Quality Index (CPSQI), using a 3-day sleep diary, and using an Actigraph sleep/activity logger watch to record several subjective and objective parameters of sleep (quality of sleep, time to bed, the onset of sleep, waking time after sleep onset, time of waking up, total sleep time, self-reported sleep onset latency, and sleep efficiency before and after the intervention). The results demonstrated a substantial improvement in subjective CPSQI score, sleep onset latency, and waking time after sleep onset. A significant increase was also noted in total sleep time and sleep efficiency. Thus, the authors conclude that eating kiwifruit may enhance sleep onset, efficiency, and duration in adults who report sleep disturbances and that further research is necessary to understand the benefits of the kiwifruit.
