Bananas are a powerhouse of nutritional value. They contain three natural sugars - sucrose, fructose and glucose combined with fibre. A banana gives an instant, sustained and substantial boost of energy. It was found that banana contained large amounts of norepinephrine and a related substance, dopamine. Large amounts of serotonin were also identified in banana. Banana also contains tryptophan that helps in restoration of essential neurotransmitters
Serotonin (5-hydroxytryptamine; SER) is a physiologically active amine which is well-known neurotransmitter that regulates mood, sleep and anxiety in mammals. Serotonin might contribute to feelings of well-being and happiness
It is one of the key neurotransmitters influencing human mood, is often referred to as the “feel good” hormone. Serotonin is one of the well-studied indoleamine neurotransmitters in vertebrates. Recently serotonin has also been reported in wide range of plant species.
The precise function of serotonin at the physiological level, particularly growth regulation, flowering, xylem sap exudation, ion permeability and plant morphogenesis in plant system has not been clear.
When banana is consumed by humans, serotonin present in the pulp (ranging from 8 to 50 µg/g) creates a feeling of well-being and happiness. Many people experiencing depression report they feel much better after eating a banana. This is because bananas contain tryptophan, a type of protein that the body converts into serotonin, known to induce relaxation, improve mood levels and generally helps us to feel happier.
