Anti-inflammatory diets could reduce depression
The idea that what you eat influences how you feel is gaining scientific support. A new analysis published in the journal Frontiers in Nutrition, funded by the John W. Brick Foundation for Mental Health and developed in collaboration with the University of California San Diego's Health Services Centers, offers the most comprehensive review to date on whether anti-inflammatory eating patterns can improve mental health in adults.
TL;DR
- A new analysis in *Frontiers in Nutrition* reviewed evidence on anti-inflammatory diets and mental health in adults.
- The review found consistent evidence linking anti-inflammatory diets, especially the Mediterranean diet, to reduced depression symptoms.
- Evidence for improvements in anxiety, stress, and quality of life was more variable.
- Anti-inflammatory diets emphasize plant-based foods, olive oil, fish, with moderate poultry, eggs, and dairy, and infrequent red meat.
- Ultra-processed foods, refined sugars, and industrial oils are largely excluded from these diets.
- The proposed mechanism involves reducing inflammation associated with mood disorders.
- Interventions tended to be more effective in individuals with pre-existing mental health conditions or elevated symptoms.
- Researchers caution that establishing causal relationships requires further investigation due to study design limitations.
