Blueberries. Packed with antioxidants, blueberries can do a lot to protect the brain. They contain anthocyanin, a phytochemical which boosts memory.
The antioxidants in the berries can slow the aging process by delaying the oxidation process and fighting free radicals, which have been linked with memory loss problems. Blueberries are also a great source of flavonoids, natural compounds that can enhance spatial memory and learning.
