A protein source associated with a great brain boost is fish -- rich in omega 3 fatty acids, essential for brain function and development. These healthy fats have amazing brain power: higher dietary omega 3 fatty acids are linked to lower dementia and stroke risks; slower mental decline; and may play a vital role in enhancing memory, especially as we get older.

For brain and heart health, eat two servings of fish weekly.
