According to Michael J. Breus, tart cherries are full of the naturally produced hormone melatonin. Melatonin has been known to be important for an individual's sleep.
Breus also recommends avocado on a rice cake and chickpeas due to the amount of carbs full of melatonin and magnesium.
Omelets are also recommended as eggs contain melatonin and L-ornithine, both of which-you guessed it-help you improve the quality of sleep.
