Dietary inflammatory index and sleep quality in southern Italian adults

Studies investigating sleep quality and the role of the negative inflammatory impact of poor sleep in the pathology of mental disorders and chronic illnesses are insufficient. In this cross-sectional study by Godos et al. (2019), the authors investigated the relationship between sleep quality and the inflammatory impact of dietary intake in a population of adults (participants of the Mediterranean healthy Eating, Aging, and Lifestyle [MEAL 2014-2015], n = 1935). Data on sleep quality was collected using the Pittsburgh Sleep Quality Index, while dietary evaluation was conducted using food frequency questionnaires and the Dietary Inflammatory Index (DII®). Analysis of the results revealed a significant reduction in sleep quality and increased sleep latency in individuals with high DII scores compared to their peers. The authors conclude that sleep quality is negatively impacted by increasing dietary inflammatory potential, an observation that can be utilized in tailoring dietary interventions that target systemic inflammation intending to enhance sleep quality and ameliorate cognitive decline.

The effectiveness of a weight-loss Mediterranean diet/lifestyle intervention in the management of obstructive sleep apnea: Results of the “MIMOSA” randomized clinical trial

While the primary treatment for obstructive sleep apnea (OSA) is continuous positive airway pressure (CPAP), this 2021 study investigates complementary therapeutic choices that may enhance therapy. The aim was to analyze whether adding a weight-loss Mediterranean diet/lifestyle intervention to the standard treatment of obstructive sleep apnea would have an additive positive effect on severity of […]

Sleep extension is a feasible lifestyle intervention in free-living adults who are habitually short sleepers: a potential strategy for decreasing intake of free sugars? A randomized controlled pilot study

There is a lack of research exploring the possibility that short sleep duration could be a modifiable risk factor for obesity, as was recently discovered. In their 4-week, free-living, parallel-design randomized controlled experiment involving 42 normally weighted, healthy individuals who had a history of short sleep duration, Al Khatib et al. (2018) evaluated the viability […]
