ReviewSleep & breathing = Schlaf & Atmung2025
Unraveling the connection between the Mediterranean diet and sleep health: from biological mechanisms to clinical implications.
Review in Sleep & breathing = Schlaf & Atmung, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe Mediterranean diet (Med-Diet) is well known for its protective effects against noncommunicable diseases and overall mortality, thanks to its anti-inflammatory, antioxidant, and neuroprotective properties. Simultaneously, sleep is increasingly recognized as a vital modifiable factor that influences health, affecting both physiological and psychological outcomes. This narrative review summarizes epidemiological evidence on how the Med-Diet impacts sleep duration and quality, examines the biological mechanisms behind these effects, and identifies areas for future research.
methodsA comprehensive search was conducted using PubMed, Scielo, Web of Science, CrossRef, Google Scholar, and Scopus. A total of 191 articles published between 2015 and 2025 were selected based on specific inclusion and exclusion criteria.
resultsGreater adherence to the Mediterranean diet is associated with better sleep outcomes, such as longer sleep duration, shorter sleep latency, higher sleep efficiency, and a lower risk of insomnia and obstructive sleep apnea, particularly among individuals with an overweight. Mechanistically, the Med-Diet promotes better sleep through various interconnected pathways, including modulation of the tryptophan-serotonin-melatonin pathway, reduction of systemic inflammation and oxidative stress, enhancement of metabolic and cardiovascular health, protection of endothelial and brain function, and regulation of gut microbiota and circadian rhythms. Nutrients like polyphenols, omega-3 fatty acids, and fiber influence neurotransmitter balance, neuroendocrine signaling, and microbial diversity, all of which support sleep and respiratory regulation.
conclusionThe Med-Diet offers a promising non-pharmacological approach to improving sleep health. Further longitudinal and intervention studies are needed to establish causality, assess effects within specific populations, and explore integrated lifestyle strategies, expanding the potential for chronic disease prevention and comprehensive health promotion.
