Do anti-inflammatory diets like the Mediterranean diet help reduce stress symptoms?
Anti-inflammatory diets, such as the Mediterranean diet, are rich in fruits, vegetables, whole grains, and healthy fats. These foods can reduce inflammation in the body, which may also help lower stress. While research is still growing, several studies suggest that eating an anti-inflammatory diet can improve mental health, including reducing symptoms of stress, anxiety, and depression.
What the research says
A 2025 scoping review found that anti-inflammatory dietary patterns, including the Mediterranean and DASH diets, led to significant improvements in mental health outcomes in 28 out of 42 randomized controlled trials 4. The most consistent benefits were seen for depressive symptoms, but improvements in stress and anxiety were also reported 4. This suggests that reducing inflammation through diet can positively affect mood and stress levels.
Omega-3 fatty acids, a key component of anti-inflammatory diets, have also been studied. A randomized trial in Saudi adults found that daily omega-3 supplementation (500 mg EPA + 250 mg DHA) for three months significantly reduced perceived stress, anxiety, and depression compared to a placebo 3. Omega-3s are abundant in fatty fish, walnuts, and flaxseeds, which are staples of the Mediterranean diet.
Other research supports the link between diet and stress reduction. For example, a 12-week breathwork intervention reduced stress in paramedic students 5, and mindfulness-based art therapy lowered stress in oncology nurses 6. While these are not dietary studies, they highlight that lifestyle approaches can effectively manage stress. The anti-inflammatory diet may work similarly by calming the body's stress response.
It is important to note that not all studies show strong effects. A meta-analysis of yoga and relaxation interventions for caregivers of children with cancer found non-significant results for stress reduction 8. This indicates that individual responses to stress management techniques can vary, and diet is just one piece of the puzzle.
What to ask your doctor
- Could an anti-inflammatory diet like the Mediterranean diet help with my stress symptoms?
- Are there specific foods or supplements (like omega-3s) you recommend for reducing inflammation and stress?
- How long might it take to notice changes in stress levels after changing my diet?
- Should I consider any tests to check for inflammation or nutritional deficiencies?
- Can you refer me to a dietitian who can help me plan an anti-inflammatory diet?
