Abstract: The quality and quantity of sleep is closely related to general health and quality of life. On the other hand, unhealthy diets in today's society are among one of the main health risk factors for non-communicable diseases. Various studies have shown a certain association between brain function and nutrition and therefore, diet could be a new target to try to improve sleep. This literature review is proposed with the aim of exploring the possible association between diet and sleep quality in adults. Methods Systematic review of the literature using Pubmed, EbscoHOST and ScienceDirect to examine studies dealing with sleep quality as a dependent variable and its relationship with diet as an independent variable published in the last 5 years. Results. The results show that a healthy and varied diet improves the quality and duration of sleep. High intakes both in quantity and energy density worsen the quality of sleep. Carbohydrates, simple sugars, saturated fats, and low vitamin and mineral intake worsen sleep quality while whole carbohydrates, protein, and omega-3 fatty acids improve it. A diet with a high inflammatory component worsens the quality of sleep. Conclusions. A healthy and varied diet rich in fibre, fruit, vegetables, complex carbohydrates and protein and low in saturated fat is associated with a better quality of sleep. Therefore, it is a promising prospect to promote dietary changes to improve the sleep-wake cycle of the general population. Possible new lines of research are detected in relation to the inflammatory potential of the diet, the intestinal microbiota and its relationship with sleep.
