A banana is an elongated, edible fruit – botanically a berry – produced by several kinds of large herbaceous flowering plants in the genus Musa. In some countries, bananas used for cooking may be called "plantains", distinguishing them from dessert bananas. Because the fruit is produced from a single ovary on the flower, a banana is actually classified as a berry, botanically speaking. So, it's an herb and a berry. Africans are credited to have given the present name, since the word banana would be derived from the Arab for 'finger'. Bananas started to be traded internationally by the end of the fourteenth century. Each banana (or finger) has a protective outer layer (called peel or skin). There is a fleshy part inside that readily spilts into three segments.. It is the only known tri-segmented fruit in the world. Both the skin and inner part can be eaten. Bananas contain fiber, potassium, folate, and antioxidants, such as vitamin C. All of these support heart health. A 2017 review found that people who follow a high fiber diet have a lower risk of cardiovascular disease than those on a low fiber diet. Bananas are both a fruit and not a fruit. While the banana plant is colloquially called a banana tree, it's actually an herb distantly related to ginger, since the plant has a succulent tree stem, instead of a wood one. The yellow thing you peel and eat is, in fact, a fruit because it contains the seeds of the plant.
