A banana is a tropical fruit known for its elongated shape and creamy texture. It typically has a vibrant yellow skin that turns brown as it ripens. Bananas are native to Southeast Asia but are now cultivated in many tropical and subtropical regions around the world. They are rich in potassium, fiber, and vitamins, making them a nutritious and convenient snack. Bananas can be enjoyed fresh, added to smoothies, baked into bread and desserts, or used as a natural sweetener in recipes.
