The fruit of the banana tree is eaten directly when ripe or as a part of fruit salads, juice, or shakes. Unripe bananas can cause severe indigestion and should be eaten only in cooked form. Also, bananas are good toppings for breakfast cereals, or as a snack for a quick burst of energy. Bananas have been an important cultural food for many different countries, although the genus of bananas, Musa, is native to South and Southeast Asia. The full scientific name of bananas is Musa acuminata. Now, bananas are grown in more than 100 countries around the world and can also be used to make fiber, banana wine, and even as ornamental decorations.
