Food and Mood: Current Evidence on Mental Health and the Microbiota-Gut-Brain Axis

Emerging research suggests that dietary modifications may improve mental health outcomes in mild cases of anxiety and depression.

• Various diets, including high-fiber and fermented diets, are associated with changes in gut microbial composition and activity.
• Randomized controlled trials indicate that dietary changes can positively influence mental health, particularly in mild cases.
• The effectiveness of supplements and probiotics on mood outcomes is inconsistent across studies.
• A bidirectional relationship exists between diet, the gut microbiome, and mood disorders.
• Current challenges in food and mood research stem from variability in research practices.
