In this episode of The Nourished Brain, I break down a new systematic review and meta-analysis titled “Nonlinear Dose–Response Relationship Between Dietary Inflammatory Index and Risk of Depression: A Systematic Review and Meta-Analysis”

I explore:
• Why chronic low-grade inflammation is now considered a key driver of mental health conditions
• The meta-analysis findings showing that higher DII scores are associated with increased depressive symptoms
• How anti-inflammatory patterns like the Mediterranean diet may support better brain health
• Key limitations of the review, including reliance on observational data and self-reported diet measures

Tune in to learn how your daily food choices may influence systemic inflammation—and ultimately, your mood and mental well-being.
