Bananas. Everyone knows what’s a banana, a yellow object that is long and whose peel also plays an important role in many of our jokes. The word banana is derived from the Arabic word “banan” meaning ‘finger’. But do you know that banana plant is not a tree, it is the world’s largest herb.
It is believed that there are almost more than 1000 varieties of banana on planet earth. Bananas could help you to feel happier as they contain tryptophan, a type of protein that the body converts into serotonin, known to promote relaxation and improve mood. A medium-sized banana contains only 95 calories, and provides a quick-but-sustained energy boost in a natural, nutritious and easily digestible form with no fat, cholesterol or sodium. The inside of a banana skin can be used to polish shoes.
