US nutrition and wellness expert Samantha Cassetty has called walnuts a product that helps sleep better, Report informs referring to wellandgood.com.
“Walnuts contain numerous compounds that are tied to healthy sleep patterns,” she said. “They’re a good source of tryptophan, an amino acid that your body uses to produce serotonin and melatonin, and both of these substances are involved in regulating your sleep.”
Further, walnuts actually contain melatonin, the hormone that governs your sleep-wake cycle that is necessary for quality sleep. Working hand-in-hand with melatonin, Cassetty notes, is the magnesium in walnuts. This relaxing mineral helps induce deep sleep.
She added that eating at least a couple servings per day, which works out to around 7 to 14 walnuts total, is ideal.
