Nutrition and Dietary Patterns
|
The Mediterranean diet has consistently demonstrated a wide array of favorable health outcomes, such as reduced risk of cardiovascular disease, type II diabetes mellitus, mental disorders, metabolic syndrome, breast cancer, neoplastic disease, and overall mortality. However, evidence of the effects of the Mediterranean diet and sleep disorders is limited. This week, the OHIS Newsletter highlights two novel studies related to the beneficial effects of the Mediterranean diet on sleep apnea and sleep quality.

Obstructive sleep apnea (OSA) is a sleep-related breathing disorder with a high prevalence around the world. The MIMOSA randomized clinical trial has demonstrated that the combination of a weight-loss Mediterranean dietary/lifestyle intervention and OSA standard care was more efficient in improving OSA severity and symptomatology than OSA standard care alone. In this study, the patients randomized to the Mediterranean arm exhibited reduced respiratory events and lower daytime sleepiness and insomnia. Moreover, additional improvements in sleep architecture and daytime sleepiness were observed when participants combined the Mediterranean diet with physical activity.

Additional evidence of the positive effects of the Mediterranean diet on sleep quality has been provided by the American Heart Association Go Red for Women Strategically Focused Research Network investigation. In this prospective cohort study, greater adherence to the Mediterranean diet predicted better overall sleep quality (higher sleep efficiency, fewer sleep disturbances, and better sleep onset latency) among a sample of US women. In particular, higher intakes of fruits and vegetables, legumes, unsaturated fat, and plant-based proteins were positively related to sleep quality.
