Studies published in the British Journal of Nutrition and Platelets have indicated that kiwi may be beneficial for cardiovascular health and may reduce the duration and severity of upper respiratory infections, respectively. But can the little green fuzzy fruit help you sleep better?
Kiwi is a potassium-rich, high-fiber fruit chock full of antioxidants and vitamin C. By any account, it is a great food to include in your diet, if eating healthy is your concern. Now, new research is suggesting that consuming kiwi just may be helpful to improve the quality of your sleep, just like a high-quality natural latex mattress can help you to sleep better.
Kiwi Sleep Study
Taiwan researchers at Taipei Medical University conducted a study on the effects of eating kiwi on sleep. What they found in the study participants was that both the quantity of sleep and quality of sleep was improved substantially simply by eating kiwi every day.
The participants of the study consisted on two men and 22 women aged 20 to 55. All study volunteers had reported some sleep problems in the form of disrupted sleep. For a one month period, each participant ate two kiwis 60 minutes prior to going to bed. Using a wrist watch, sleep quality questionnaire, and a sleep diary, the researches collected information about the participants’ sleep.
After the month was up, the researchers found some significant improvements in sleep.
- 35.4 percent decrease in the time it took to fall asleep after going to bed.
- 28.9 percent decrease in wakefulness period after initial sleep onset.
- 42.4 percent improvement in scores on a standardized sleep quality questionnaire.
- 5.41 percent increase in time spent sleeping compared to total time in bed.
- 13.4 percent increase in total sleep time.
What’s the possible link between improvements in sleep and kiwi fruit? Experts believe that it is a combination of the fruit’s high serotonin levels coupled with its high antioxidant levels.
So, should you add kiwi to your bedtime rituals and to the list of foods that may help you sleep, like warm milk, bananas, and chamomile tea? Clearly, this is only one study, and more research is needed to determine the causal relationship between kiwi fruit and sleep. But by many accounts kiwi fruit is one of nature’s superfoods. It’s a nutrient dense food that is believed to offer all sorts of health benefits, including decreased risk of obesity, improved look of skin, reduced risk of cardiovascular disease — and now, quite possibly better sleep quantity and quality.
