Brain Foods

Keeping cognitive function at its peak performance is a goal for many people, as the effects of aging can have you feeling like you are not yourself mentally anymore. While there is no food that guarantees a cognitive boost, a change in diet will help slow cognitive and memory decline.


  • Green, Leafy vegetables: Vegetables such as kale, spinach, broccoli, and collards are high in vitamin K, lutein, folate, and beta carotene, all of which are linked to a decrease in cognitive decline.
  • Fatty Fish: Fatty Fish contain large amounts of omega-3 fatty acids, which reduce the prevalence of a protein found to be linked to Alzheimer’s. Make sure to choose a fish low in mercury content such as salmon or cod.
  • Berries: Berries are high in a pigment called flavonoids. This pigment has been linked to delayed memory decline.
  • Tea and Coffee: The caffeine contained in tea and coffee has been shown to offer more than just alertness for a short period of time. In studies, it shows that caffeine, in moderate amounts, helps solidify new memories, and increases mental function overall.
  • Avocado and Walnuts: Avocado and Walnuts are both high in omega-3 fatty acids, which, as discussed previously, reduce the prevalence of a protein linked to Alzheimer’s. These foods are also shown to increase memory.


  • Make sure to add these foods to your regular diet, as eating them just one time will not provide results.
  • Eat these foods in moderation, as overindulging in anything will provide negative results.
  • Combine this change in diet with exercise for increased cognitive function.
