Association between dietary phytochemical index, inflammation and oxidative stress with sleep duration and sleep quality in Iranian adults

Key Points

• Sleep quality is positively influenced by a higher dietary phytochemical index and lower inflammation levels.
• A significant correlation shows that individuals with better sleep were associated with lower oxidative stress and inflammation levels.
• Observational analysis assessed dietary phytochemical intake and its relationship with sleep metrics across a diverse adult population.
• These findings may indicate potential dietary changes to enhance sleep quality, but further studies are needed to confirm causality.
