Bananas are a superfood in general due to the fact that they consist of many good vitamins and minerals needed for general health, among which may be singled out those that have a positive and noticeable impact on the functioning of the brain. But is this the case? That banana enhances brain activity? The answer lies in the nutritional profile that characterizes it.
Nutrients in Bananas Supporting Brain Health
Bananas are a good source of potassium, vitamin B6, and antioxidants-all factors that contribute to brain health. Potassium is an important electrolyte in the normal functioning of nerves, participating in the process that sends signals from one neuron to another. Moreover, potassium enhances concentration and mental alertness.
Vitamin B6 is highly involved in the synthesis of neurotransmitters such as serotonin and dopamine. These chemicals are the ones controlling mood, attention to things, and memory. A deficit in vitamin B6 intake has been attributed to cognitive decline and disturbed brain activity. Banana is one of the finest natural sources of this vitamin and hence can help one fulfill one's requirements to help support optimal brain activity.
Bananas also contain tryptophan, an amino acid that the body converts into serotonin. Sometimes referred to as the "feel-good" neurotransmitter, serotonin impacts mood, sleep, and cognition. Indirectly, it improves brain function by giving mental clarity and a decrease in stress.
Antioxidants and Brain Protection
One medium banana contains several antioxidants, such as dopamine and catechins, which have been demonstrated to resist the process of oxidative stress in the brain. When free radicals build up in the body and there is not enough balance with antioxidants, oxidative stress results and could be a contributing factor to neurodegenerative diseases and a decline in cognitive abilities. Antioxidants in bananas neutralize free radicals and are thus believed to protect the brain cells from damage that could lead to conditions such as Alzheimer's disease and dementia.
The Bottom Line
Although having a single banana alone is not going to drastically improve one's intelligence, incorporating them into a diet will indeed foster brain activity over time. Nutrients in bananas support brain function, concentration, and protect the body against oxidative damage. If one is looking for something quick but healthy to snack on to get that extra boost to the brain, then a banana is just what one needs.
