10 Health Benefits of Kiwi Fruit

Kiwis contain serotonin and may promote better sleep.

Kiwi may also help you have more restful sleep. This zingy fruit is high in serotonin, a neurotransmitter that's the precursor to melatonin, the main hormone charged with maintaining healthy sleep patterns. Though completed a little over a decade ago, one small study examined kiwi’s impact on sleep in 24 adults over four weeks. Researchers found that eating two kiwis one hour before bedtime was associated with "significantly" improved overall sleep time, sleep efficiency, and ability to fall asleep more quickly (sleep onset).
