Food for thought: how nutrition impacts cognition and emotion

This review explores how nutrition influences brain function, cognition, and emotions throughout life. Poor diets rich in saturated fats and low in nutrients like omega-3 fatty acids or polyphenols are linked to inflammation, cognitive decline, and mood disorders. Conversely, diets high in omega-3s, fruits, and vegetables help prevent or reverse these effects by reducing brain inflammation and oxidative stress. Early-life nutrition is especially critical for brain development, with long-term impacts on memory and emotional health. The findings emphasize how diet shapes brain resilience and function at every age.

Include nutrient-rich foods like fish, berries, and leafy greens to support brain health. Minimize high-fat and processed foods to avoid inflammation-related cognitive and emotional issues. Early dietary interventions are particularly beneficial for lasting brain health and mood stability.
