Mediterranean diet, mental health, cognitive status, quality of life, and successful aging in southern Italian older adults

This study explored how adherence to the Mediterranean diet impacts mental and cognitive health, sleep quality, and quality of life among older adults in Sicily. Researchers found that individuals closely following this diet had lower odds of cognitive impairment and depressive symptoms and were more likely to report good quality of life and sleep quality. The Mediterranean diet, rich in fruits, vegetables, whole grains, fish, and olive oil, may promote brain health by reducing inflammation, enhancing brain plasticity, and supporting neurogenesis, crucial for cognitive resilience and successful aging.

Adopting a Mediterranean diet—emphasizing fruits, vegetables, whole grains, nuts, olive oil, and fish—may enhance brain health and overall well-being. This recommendation is supported by observational evidence, showing strong associations but not causation, highlighting the need for individualized dietary advice.
