Walnuts are a great way to get the restful sleep your body needs. They contain high amounts of melatonin, which is a hormone that helps regulate our body's sleep-wake cycle. Studies have found that consuming walnuts prior to bedtime can help you fall asleep faster as well as stay asleep longer. Additionally, they contain tryptophan, and omega-3 fatty acids - nutrients that are involved in melatonin and serotonin synthesis, both involved in regulating sleep. Furthermore, walnuts are also a great source of protein, healthy fats and antioxidants, making them an excellent snack choice before bed. So if you're looking for natural methods to get more restful sleep, try adding some walnuts into your evening meal!
