Carbohydrates
Foods that are rich in starchy, high-glycemic carbohydrates may also promote better sleep, as they help to stimulate the release of insulin and tryptophan and cause these sleep-inducing substances to enter the brain. According to a study published in The American Journal of Clinical Nutrition, carbohydrates that are on the high end of the glycemic index scale, meaning they increase the body�s sugar levels rapidly, encourage sleep when eaten at least four hours before bedtime. Foods such as Jasmine rice, potatoes, carrots, corn, puffed cereal, and honey are some of the healthiest choices of simple carbohydrates.
