Avocados – Often dismissed because of their high concentrations of fat, this single-seeded berry is packed with potential brainpower. Its high monosaturated fat content helps protects the brain cells responsible for supporting information-carrying nerves, while its unsaturated fat content works to keep cell membranes flexible. Avocados are also rich in vitamin K and folate, both of which help prevent blood clots from forming in the brain, as well as improve memory and concentration. Beets – While beets are chock full of anti-inflammatories and antioxidants, this root vegetable made the list for its natural blood-boosting nitrates. The brain is dependent upon a healthy flow of oxygen supplied through a healthy flowing bloodstream. Too little oxygen, and brain cells start dying and struggling to function. Add in some nitrate and it’s a different story, making beets a great way to improve cognitive ability and concentration as well as sharpen the mind. Not only that, the added nitrates mean more oxygen availability during exercise, which is believed to promote the growth of grey brain matter. Blueberries – One of the most nourishing superfoods out there, blueberries are rich in vitamins C and K, fiber and anti-inflammatories. These tiny blue spheres contain the highest concentration of antioxidants out of all other natural ingredients, and the benefits for the brain seem endless. Regular consumption of blueberries is linked to improvements in: spatial memory (recollection of geographical landscapes and interior layouts), motor function, memory processes, absorption of new information and learning pace, as well as greater mental clarity. Additionally, these fruits have high concentrations of gallic acid, which has antiviral and antifungal properties and helps protect the brain from degeneration. And to top all that off, blueberries are rich anthocyanin, a polyphenol compound capable of crossing the blood-brain barrier with anti-inflammatory effects that work to restore the flow of communication between neurons.
