However, the impact of chrono-nutrition on sleep remains less explored. Here we conducted a systematic scoping review, considering the multiple dimensions of chrono-nutrition, to describe the extent, range, and nature of the existing literature in this area (PROSPERO: CRD42021274637). There has been a significant increase in the literature exploring this topic over the past six years (almost 67 % of the evolving literature). A breakdown of the included studies was performed according to three major chrono-nutritional dimensions: meal timing [n = 35], irregular eating patterns [n = 84], and frequency of eating occasions [n = 3]Sleep medicine reviewsChrono-nutrition and sleep: lessons from the temporal feature of eating patterns in human studies - A systematic scoping review.PMC12090848R35 HL155670R01 HL142648R01 DK128154Dambel LRochette ESt-Onge MPDuche PSaidi OfalseChrono-nutrition and sleep: lessons from the temporal feature of eating patterns in human studies - A systematic scoping review.An emerging field of research has revealed a bidirectional relationship between sleep and diet, highlighting the potential role of a healthy diet in improving sleep.
