Bananas have a high level of potassium. Therefore, they are a good food for overall health. Bananas supply potassium to the brain, helping to keep oxygen levels regulated and also promoting strong signals between cells.
Bananas are a good source of the vitamin B6. The vitamin is crucial to the development of serotonin.
The tryptophan in bananas works to elevate the mood by stimulating serotonin production. Serotonin helps keep the mood stable and bright. This enhances brain function by eliminating the foggy thinking of depressive tendencies.
Bananas are known to help induce sleep. A few slices of a banana are a great pre-bedtime snack. Eating a banana before sleep may help ensure deep rest. The brain functions at its best when deep slumber occurs and a person awakes feeling refreshed and energized.
Bananas are also a rich source of fiber. This fiber helps to stabilize overall health and ensure that the digestive system is functioning smoothly. When overall health is strong, the brain is able to work at its strongest capability as well.
