The MD is one of the most extensively researched dietary patterns, with a plethora of reliable scales measuring adherence. However, the consumption of NFFs grown and produced in the Mediterranean region is currently missing from its measurement scales. The current study attempted to fill this void. To our knowledge, this is the first study to investigate the relationship between NFFs, the MEDLINE, and their association with PsyR and health-related parameters such as sleep and long-term dieting results. The findings of this study confirmed our hypothesis that NFFs grown and produced in the Mediterranean region, such as whole grains, edible wild greens, herbal infusions, bee products, raisins, seeds, berries, cruciferous vegetables, fermented dairy products, and herbs/spices, are associated significantly with the MD and other components of the

This hypothesis was also supported by the fact that functional foods more closely associated to a Western diet pattern, such as milk, cocoa/chocolate, coffee, and fortified foods, were not associated with adherence to the MD or to the MEDILIFE. The only exceptions were cocoa/chocolate consumption, which was linked to sleep routine, and fortified food consumption, which was linked to physical activity and meal routine. These results confirmed previous findings that cocoa/chocolate may have a beneficial effect on circadian desynchrony [57] and that fortified food consumers may exhibit behaviours corresponding to our study's behaviours [58]. The consumption of NFFs associated with the MEDILIFE had a positive effect on health, both individually and synergistically. Grouping these NFFs into the NAFFAME tool to assess the synergistic effect of their consumption revealed a statistically significant correlation of NAFFAME with the MD, PsyR, sleep quality, and body weight. ANOVA and independent-samples tests further confirmed this association, while multinomial logistic regression analysis revealed that NAFFAME score could predict the PsyR and BMI of the study's participants. The relationship between nutrition and mental health has been underappreciated in recent decades. This trend has shifted in recent years, with interest growing in neuropsychiatric research [5]. PsyR is an essential component of mental health, and its promotion may be critical to people's mental health and well-being. Sleep quality is another factor that, as demonstrated by a recent meta-analysis of randomised controlled trials, leads to improved mental health [59]. The research on functional foods and their relationship to mental health and sleep quality is still in its infancy, with a limited number of articles studying this link [5, 13, 60]. The association of NAFFAME with both PsyR and sleep quality, as demonstrated by this study, adds to the ongoing psych-dietetics research. A plethora of parameters, such as the brain-intestinal axis and gut microbiota, possibly affect sleep quality, body weight, and neuropsychology [61, 62, 63, 64]. Contrary to the limited evidence on the link of nutrition to mental health, nutrition's relation to physical health and body weight has been vigorously researched.
