Banana is the common name for a type of fruit and also the herbaceous plants of the genus Musa which produce this commonly eaten fruit. They are native to the tropical region of Southeast Asia. Bananas are likely to have been first domesticated in Papua New Guinea. Banana plants are of the family Musaceae. They are cultivated primarily for their fruit, and to a lesser extent for the production of fibre and as ornamental plants. By a high potassium to sodium content, bananas may prevent high blood pressure and its complications.
In diarrhea, it contributes with electrolyte replacement, as well as increased absorption of nutrients. Bananas also have some antacid effect, protecting from peptic ulcers. Pectin content, a hydrocolloid, can ease constipation by normalizing movement through the intestine. Banana fibre is also used in the production of banana paper. Banana paper is used in two different senses: to refer to a paper made from the bark of the banana plant, mainly used for artistic purposes, or paper made from banana fiber, obtained from an industrialized process, from the stem and the non usable fruits. This paper can be either hand-made or made by industrialized machine.
In the current world marketing system, bananas are grown in the tropics. The fruit therefore has to be transported over long distances and storage is necessary. To gain maximum life, bunches are harvested before the fruit is fully mature. The fruit is carefully handled, transported quickly to the seaboard, cooled, and shipped under sophisticated refrigeration.
