The fruits of the Cavendish bananas are eaten raw, used in baking, fruit salads, and to complement foods. The outer skin is partially green when bananas are sold in food markets, and turns yellow when the fruit ripens. As it ripens the starch is converted to sugars turning the fruit sweet. When it reaches its final stage (stage 7), brown/black “sugar spots” develop. When overripe, the skin turns black and the flesh becomes mushy. Due to their phallic shape, they are sometimes used in sexual education classes to demonstrate the correct usage of a condom.
