Article Review: Kiwi Fruit and its effect on sleep!
Article: Lin, H.H., Tsai, P.S., Fang, S.C. and Liu, J.F., 2011. Effect of kiwifruit consumption on sleep quality in adults with sleep problems. Asia Pacific journal of clinical nutrition, 20(2), p.169.
Design: A free living, self-controlled diet design. Where 24 (2M, 22F) were instructed to eat 2 kiwifruits 1 hour before bed for 4 weeks.
Finidings: Kiwi fruit consumption objectively increased the total sleep time and the sleep effieceny(how often they woke during the sleep) by 16.9% and 2.4% respectively. Whereas subjectively there was a decrease in the time onset of sleep (how quick they fall asleep) and waking after sleep onset (how long they are awake) during sleep by 28.9% and 35.4%.
My Thoughts: This was really cool and different! Kiwi fruit are known to have high dosages of Kiwifruit is rich in antioxidants, vitamins C and E, flavonoids, folate, anthocyanins, and carotenoids, and it contains approximately twice the concentration of serotonin as tomatoes.
The biggest take away is that with stress, oxidative stress in the body is elevated, antioxidants play a viral roll here. With stress you also have a loss of serotonin in the brain, another roll kiwifruits may have here.
