Is consuming red meat associated with obstructive sleep apnea? A systematic review.

Purpose: This review aims to explore the relationship between obstructive sleep apnea (OSA) and red meat consumption, exploring the potential impact of dietary choices on sleep-disordered breathing. Sleep apnea has been associated with various lifestyle factors, and equally, red meat has been associated with inflammation and obesity, both risks for OSA.

Methods: We searched the literature using Embase and PubMed for relevant studies published from inception to March 2024, using the following search terms: ("red meat" OR "processed meat" OR "unprocessed meat") AND ("obstructive sleep apnea" OR "sleep apnea" OR "sleep-disordered breathing"). The review incorporates clinical studies, observational research, and investigations. Moreover, potential confounding factors and the need for further research to establish causation are critically evaluated.

Results: Seven studies fit our inclusion criteria and directly addressed the effect of red meat on OSA, demonstrating a potential bidirectional relationship between red meat and individuals with OSA. Mechanisms of oxidative stress and obesity have been postulated.

Conclusion: This review aims to provide an understanding of the dietary aspects influencing sleep by shedding light on the potential contribution of red meat consumption to OSA. Insights derived from this exploration could inform lifestyle modifications and dietary interventions for individuals at risk of OSA.
