Bananas are rich in vitamins A, C and B6, fiber, carbohydrates, protein, iron, phosphorous, tryptophan, and potassium, a mood lifting combination of nutrients. The tryptophan gets absorbed with the help of carbohydrates, and then, with assistance from vitamin B6, gets converted into the feel good hormone: serotonin. The potassium in them keeps you feeling energized by keeping the fluid levels balanced and the iron in them helps prevent lethargy.
