Nutrition guidelines that support optimal brain health emphasize a diet rich in antioxidants, healthy fats, vitamins, and minerals. Consuming foods high in omega-3 fatty acids, such as fish, nuts, and seeds, is particularly beneficial for cognitive function. Incorporating plenty of fruits, vegetables, and whole grains provides essential nutrients and reduces inflammation. A balanced diet that limits saturated fats and processed sugars also supports long-term brain health. Staying hydrated is equally vital, as even mild dehydration can negatively affect cognitive performance.
