Why are bananas pink?

Bananas are not normally pink. They are typically yellow or green, depending on the ripeness of the fruit. Pink bananas are a relatively uncommon occurrence and can be caused by a number of factors including:

- Pink banana disease: This is a fungal infection that can cause bananas to turn pink. The fungus, which is known as Fusarium oxysporum f. sp. cubense, enters the banana plant through the roots and moves up the stem, causing the fruit to turn pink and eventually rot.

- Chilling injury: Bananas that have been exposed to cold temperatures for too long can also turn pink. This is because the cold damages the banana's cell membranes, causing the release of enzymes that turn the fruit pink.

- Other causes: In some cases, bananas can also turn pink due to other factors such as insect damage or bruising.

Pink bananas are generally safe to eat, although the taste and texture may be affected by the discoloration. If you see a pink banana, it is best to eat it as soon as possible to avoid further spoilage.
