New treatment option for Sleep
Official title Dietary Impact on Sleep, Rhythms and Related Physiology
ClinicalTrials.gov ID: NCT07138313
What this study is testing
- What it's testing
- Sleep and metabolism are closely interconnected, and emerging evidence suggests that dietary composition may influence both sleep quality and key physiological functions such as glucose regulation, cardiovascular activity, and hormonal signaling. This study aims to investigate how a Western-style unhealthy diet versus a healthier, fiber-rich diet affects objective and subjective sleep measures, 24-hour physiological parameters, and a range of biomarkers related to cardiometabolic, neurodegenerative, and gut microbial function.
