“…Four studies 36,[41][42][43] examined macronutrient manipulation at an evening meal and effects on sleep duration and quality; only one 41 reported significant effects (Table 1). All studies manipulated the CHO and fat content of the meals.…”

“…77 This could result in differences in nutrient metabolism and bioavailability between test meals, especially when protein levels are not matched. For example, one study had a lower energy content but a higher percentage of protein as energy, 43 which could bias results toward the null. Third, whenever possible, test foods and meals should be as similar to each other as possible to also avoid the possibility of confounding.…”

Aim: The aim of this systematic review was to characterise and synthesise the literature that explores the effects of macronutrient manipulation on sleep outcomes in order to provide dietary recommendations for sleep improvement. Methods: Intervention studies that evaluated the effects of macronutrient manipulations on sleep were identified using four databases. A study was included if it: (a) delivered a macronutrient-based dietary intervention, regardless of length;(b) included healthy human participants aged 18 and older; and (c) measured some aspect of sleep, for example, duration or quality, in some manner. Results: A total of 17 papers and 19 studies met the inclusion criteria.Included studies were organised into acute studies lasting less than 24 hours (n = 4), longer-term (≥24 hours) studies (n = 10), and energy restriction studies (n = 5). The greatest amount of support was observed for longer-term administration of higher carbohydrate diets. These interventions positively influenced rapid eye movement sleep; however, non-rapid eye movement sleep was negatively affected. The overall health outcomes of these changes are difficult to assess. Limited evidence suggests higher protein diets under conditions of energy restriction can improve sleep quality, but these effects might be restricted to individuals with overweight or obesity. Current evidence does not support the effects of acute macronutrient manipulation, defined as less than 24 hours, on sleep outcomes. Conclusions: Manipulating carbohydrate intake for at least 24 hours appears to alter sleep outcomes among healthy individuals. Interventions were highly varied and methodological shortcomings were identified. More work is required to fully understand how macronutrient intake affects sleep outcomes.

Objectives To evaluate an association between eating patterns and sleep quality in Chilean university students. Methods A cross-sectional analytical study was conducted. Participants included students from 4 Chilean universities. Each student was administered survey Questionnaire on the frequency of healthy and unhealthy eating habits and Pittsburgh Sleep Quality Index and their weight and height were taken to obtain the Body Mass Index (BMI). Results A total of 1,079 young university students, 80.26 % were women and the average age was 21.7 years. The 73.68 % have inadequate sleep quality. There is a significant differences in frequency between sleep quality and the intake of breakfast (p<0.001), fish (p<0.05) and dinner (p<0.05), that is, university students who reported optimal sleep consume breakfast and dinner on a daily basis and their fish intake is in line with nutritional recommendations. With respect to the association between sleep quality and healthy dietary patterns, it is observed a significant association (p<0.01) between optimal sleep and daily breakfast consumption in model 3 (Odds Ratio (OR): 0.61 (0.46–0.82)). Regarding unhealthy dietary patterns, a significant association (p<0.05) is observed in model 3 between sleep quality and alcohol consumption (OR: 1.42 (1.02–1.96)). Furthermore, a significant association between optimal sleep and salt consumption is observed in both model 2 (OR: 0.73 (0.54–0.99)) and model 3 (OR: 0.72 (0.53–0.97)). Finally, a significant relationship between not tobacco use and optimal sleep is observed (OR: 0.68 (0.48–0.96)). Conclusion A positive relationship between healthy diet and sleep quality was observed in university students, which certain dietary patterns, such as the consumption of breakfast and low salt consumption and alcohol, are crucial to talk about a good sleep quality in this population group.
