Did you know that generally complex carbohydrates such as quinoa, barley, wheat, and buckwheat, promote sleep? And speaking of carbs, bananas are also carbs. They also contain magnesium, a natural muscle relaxant, as well as potassium. That makes bananas a win-win because humans needs potassium for cardiovascular health and cognitive brain functioning. You might try a sweet potato snack, too. Sweet potatoes are a sleeper’s dream. They provide sleep-promoting complex carbohydrates plus potassium, a muscle-relaxant potassium. Lima beans and papaya also contain potassium. And then there’s turkey, which contains tryptophan, a chemical that can make you doze off after Thanksgiving dinner. According to Russell Rosenberg, PhD and CEO of the National Sleep Foundation, if you’re a die-hard insomniac, you’d have to eat a lot of turkey to have a major effect, but if you need a little shove in the right direction, it just might help.
