5 Excellent Brain Foods Here are 5 excellent brain foods that help boost memory, focus, and overall mental health: Fatty fish (e.g., salmon, sardines, mackerel) – Rich in omega-3 fatty acids, which support brain cell structure and improve communication between neurons. Blueberries Packed with antioxidants that protect the brain from oxidative stress and improve memory. Blue colour is actually due to polyphenols that are antioxidants. Walnuts Contain DHA (a type of omega-3) and antioxidants that improve cognitive performance. Dark chocolate In moderation, it boosts blood flow to the brain and improves mood and focus due to flavonoids and caffeine. Leafy greens (e.g., spinach, kale, broccoli) – High in vitamin K, lutein, and folate, which help slow cognitive decline.
