Kiwifruit possess numerous vitamins and minerals, most notably vitamins C and E as well as potassium and folate. Some research has found that eating kiwi can improve sleep.

Several studies have found sleep benefits for people who drink tart cherry juice. These benefits may come from the fact that tart cherries have been found to have above-average concentrations of melatonin, which is a hormone that helps regulate circadian rhythm and promote healthy sleep. Tart cherries may also have an antioxidant effect that is conducive to sleep.

Nuts like almonds, walnuts, pistachios, and cashews are often considered to be a good food for sleep. Though the exact amounts can vary, nuts contain melatonin as well as essential minerals like magnesium and zinc that are essential to a range of bodily processes. In a clinical trial using supplements, it was found that a combination of melatonin, magnesium, and zinc helped older adults with insomnia get better sleep.           

Nutritionists recommend eating a balanced and consistent diet that is made up mostly of vegetables and fruits. Properly designed, such a diet provides stable sources of essential vitamins and minerals, including those that can promote sleep. An example of this type of diet, the Mediterranian Diet, has been associated with heart health as well as with better sleep.
