Nutrition Across the Lifespan: A Lifelong Approach to Brain Health and Cognitive Resilience

Nutrition is critical to shaping brain health and cognitive resilience throughout the human lifespan, from early childhood to aging. During early development, nutrient-dense foods are required to support brain plasticity and function; deficiencies in important nutrients such as omega-3 fatty acids and vitamin D have been associated with compromised cognitive abilities. In adults, dietary patterns rich in antioxidants, anti-inflammatory foods, and healthy fats help protect against cognitive decline and mental health disorders. Under the increased burden of oxidative stress and inflammation, the aging brain benefits from diets emphasizing antioxidants and high-quality proteins for maintaining cognitive function and preventing neurodegenerative diseases. Although evidence has strongly linked diet to brain health, more research is required to explore how specific nutrients, dietary patterns, and life-stage interventions contribute to cognitive resilience. This editorial underlines the importance of a life-course approach to nutrition and the need for personalized strategies for all ages to optimize brain health and mitigate age-related cognitive decline.
