What Foods Are Considered Brain Fuel?

Dark fruits and veggies, fish, eggs, oatmeal, caffeine and water are considered brain fuel, explains Prevention magazine. These foods provide the vitamins, minerals, antioxidants, fatty acids and carbohydrate energy that the brain requires to function and thrive.

Blueberries and raspberries contain antioxidants that are believed to build strong connections between brain cells, explains Prevention magazine. Leafy green and cruciferous vegetables, such as spinach and broccoli, are rich in carotenoids and B vitamins. Carotenoids are antioxidants that protect the brain, and B vitamins can improve memory and alertness, states WebMD.

Salmon, mackerel, herring, sardines and trout are sources of omega-3 fatty acids, explains WebMD. So are fortified eggs. Omega-3s help to maintain brain capacity and concentration. Salmon also contains B vitamins and selenium, a mineral.

Glucose is the brain's main source of energy, states Prevention magazine. Fiber-rich oatmeal stabilizes blood glucose levels and provides the brain with a steady stream of carbohydrate fuel. Coffee can deliver temporary boosts in alertness and brain power, though it should be consumed in moderation. WebMD recommends no more than two cups per day.

An Ohio University study found that students who remained hydrated scored much better on tests than students who were not drinking enough water, reports Prevention magazine. The average brain is 75 percent water, and dehydration impairs brain capacity. Prevention advises drinking six to eight glasses of water daily.
