Healthy fats play a critical role in brain health by supporting the structure of brain cells and influencing cognitive function. Omega-3 and omega-6 fatty acids, found in sources like fish, nuts, and seeds, can improve memory, mood, and overall brain function. They may also reduce the risk of neurodegenerative diseases and support heart health, which is closely linked to brain health. Incorporating healthy fats into the diet helps maintain optimal brain function throughout life.
