Food help for major depression

~21 million Americans have major depressive disorder (MDD) annually (NIMH). 8% of adults. Women have 2x prevalence. Depression is the #1 cause of disability globally. Diet is a powerful modifiable factor: the SMILES trial (2017) showed Mediterranean diet with dietitian produces remission in 32% vs 8% control at 12 weeks.

SMILES study — diet as treatment

Felice Jacka et al. (2017) randomized 67 adults with moderate-severe depression to Mediterranean diet with dietitian vs. social support. Results:

• Clinical remission 32% (diet) vs 8% (control).
• Average HAM-D reduction 11 points vs 4.
• Cost ~$26/person/week — much less than many antidepressants.
• Replicated in HELFIMED, AMMEND, MoodFOOD trials.

Mediterranean diet for depression

• Fatty fish 2-3x/week — salmon, sardines. Omega-3 EPA >1 g/day.
• Dark green vegetables 6+ servings/week — spinach, kale (folate).
• Other vegetables 1+ serving/day.
• Berries, fresh fruits.
• Whole grains — oats, quinoa, brown rice.
• Beans, lentils — B6, folate.
• Nuts, seeds — magnesium, omega-3.
• Extra virgin olive oil — primary fat source.
• Unsweetened yogurt, kefir — probiotics.
• Chicken and eggs — moderate.
• Green tea.

What to avoid

• Ultra-processed foods — NutriNet-Santé 2024 study showed 20% higher depression risk per 10% more ultra-processed foods.
• Added sugar.
• Alcohol — CNS depressant; worsens depression.
• Processed meats.
• Trans fats.

Evidence-based supplements

• Omega-3 EPA >1 g/day — meta-analysis shows efficacy comparable to SSRI for mild-moderate depression.
• Vitamin D 1,000-4,000 IU/day — common deficiency; correlates with depression.
• Folate/L-methylfolate (Deplin) — augments SSRI efficacy; especially useful with MTHFR mutation.
• Vitamin B12 — common deficiency; values <500 pg/mL associated with depression.
• Magnesium glycinate 200-400 mg/night.
• Combined vitamin D + omega-3 — synergy.
• SAMe (S-adenosylmethionine) 800-1,600 mg/day — comparable to tricyclics in European studies. Check with doctor (can precipitate mania in bipolar).
• St. John's Wort 300 mg 3x/day — comparable to SSRI for mild-moderate depression. DO NOT combine with SSRI (serotonin syndrome) or with contraceptives.
• Psychobiotic probiotics: Lactobacillus, Bifidobacterium — gut-brain axis.
• Curcumin 500-1,000 mg/day — meta-analysis suggests benefit.
