Antidepressant foods: An evidence-based nutrient profiling system for depression

Area of Science:

• Nutritional Psychiatry
• Dietary Science
• Mental Health Research

Background:

• Depressive disorders are a significant global health concern.
• Nutritional factors are increasingly recognized for their role in mental health.
• Identifying specific nutrient-dense foods is crucial for dietary interventions.

Purpose of the Study:

• To identify the most nutrient-dense food sources of nutrients linked to depression prevention and recovery.
• To develop a scoring system for ranking foods based on their antidepressant nutrient content.

Main Methods:

• Systematic literature review to identify "Antidepressant Nutrients".
• Nutritional data analysis using USDA database for selected foods.
• Development and application of an Antidepressant Food Score (AFS) for nutrient density.

Main Results:

• Twelve key "Antidepressant Nutrients" were identified, including folate, iron, omega-3 fatty acids, magnesium, and B vitamins.
• Highest-scoring animal foods included oysters, mussels, seafood, and organ meats.
• Highest-scoring plant foods included leafy greens, lettuces, peppers, and cruciferous vegetables.

Conclusions:

• The Antidepressant Food Score (AFS) effectively identifies foods rich in nutrients supporting mental health.
• Specific animal and plant-based foods are highlighted as valuable dietary options for depression.
• Findings can inform future research and clinical dietary recommendations for depression.
