This review explores how nut consumption benefits cognitive health through antioxidant, anti-inflammatory, and gut microbiota-modulating effects. Nuts like walnuts, almonds, and pistachios are rich in bioactive compounds such as polyunsaturated fats, polyphenols, and antioxidants. These compounds combat oxidative stress and inflammation—key contributors to cognitive decline. While epidemiological studies suggest that regular nut intake reduces risks of cognitive disorders, clinical evidence remains limited and inconsistent. Nuts also influence gut health, potentially supporting the gut-brain axis. The review emphasizes the need for larger, controlled trials to confirm these effects in humans.
Consume a moderate daily serving (30 g) of mixed nuts like walnuts, almonds, or pistachios to support brain health. Nuts' bioactive compounds may reduce oxidative stress and inflammation, enhancing cognitive resilience, especially with aging. However, current evidence is largely observational and requires more robust clinical trials for confirmation. Integrate nuts into a balanced diet, and avoid overconsumption to manage calorie intake. Consult a healthcare provider if you have allergies or dietary restrictions.
