Who needs a sleeping pill when a nut can do the job? Scientists at the University of Texas have discovered that Walnuts are one of the few foods which offer the sleep-regulating hormone called melatonin. Because the body’s melatonin production decreases overtime, depletion of the hormone has been related to age-related diseases like Alzheimer’s.

A single gram of walnut contains 2.5 to 4.5 nanograms of melatonin. The researchers are now trying to determine how many walnuts are needed to help you drop off.
