Bananas are herbaceous plants of the genus Musa that produce fruit. They come in various sizes and colors when ripe, including yellow, purple and red. Bananas are native to tropical South and Southeast Asia and were first domesticated in Papua New Guinea. Bananas provide energy and nutrients like tryptophan, which produces serotonin to improve mood, as well as potassium, fiber, and iron. They can help manage conditions like high blood pressure, heart health, digestive issues, and anemia.
