The relationship between diet and sleep

Researchers found that eating more saturated fat and less fibre from foods like vegetables, fruits, and whole grains led to reductions in slow-wave sleep - the deep restorative kind of sleep.

People who consume a high-carbohydrate diet fall asleep much faster at night, but the quality of carbs matters. People who eat simple carbs and sugar tend to wake up more frequently throughout the night while eating complex carbs that contain fibre may help you obtain more deep, restorative sleep. This is because complex carbohydrates provide a more stable blood sugar level.
