Banana

Are you feeling depressed right now? You might consider eating a banana. Bananas contain trytophan, a type of protein that the body converts into serotonin, the hormones that make us relax, lift our mood, and make us feel happier. Bananas contain three natural sugars - sucrose, fructose, and glucose, combined with fiber. So the next time that you need a boost of energy without the bad calories, why not forego the donut and grab a banana instead?
