Abstract: A great deal of research has demonstrated that the macronutrients protein and carbohydrate in foods have a major influence on sleep. However, results from different studies are inconsistent, so it remains unclear how protien and carbohydrate affect sleep. This review has summarized the recent studies on the effects of protien and carbohydrate on sleep, revealing that high-carbohydrate low-protein foods may be helpful to promote sleep and improve sleep quality. This review may provide a theoretical guidance for improving sleep based on dietary nutrients.

Key words: sleep; food; protein; carbohydrate
