Nutrition and Sleep Medicine

In the last few decades, a significant increase in the prevalence of sleep disorders have been observed. Behavioral risk factors, such as alterations in dietary habits, attributable to the transition from healthy dietary patterns characterized by a high intake of plant-based foods to Western-like dietary patterns characterized by a high intake of processed foods deprived of essential nutrients, have been identified among major contributors. Current evidence suggests that the link between diet and sleep is bidirectional, with diet quality and dietary intakes influencing hormonal balance and sleep affecting biological and behavioral habits. Although numerous studies have been conducted hereof, the evidence is not univocal, and studies considering variables, such as chrono-nutrition and the impact on gut-microbiota, are of paramount interest.

This Research Topic aims to provide an overview of the current state of knowledge and new insights on the link between diet and sleep.

This Research Topic welcomes the submission of original contributions, including clinical trials and observational studies, as well as reviews and meta-analyses of published literature exploring and summarizing the evidence on the link between diet and sleep.
