Areas of Concern
Below are the main things you want to pay attention to if you're thinking about feeding your bearded dragon bananas.Dangerous Calcium to Phosphorus Ratio
Bananas contain five-times more phosphorus than calcium. This is a concern because phosphorus blocks calcium absorption. A simple trick is to assume each mg of phosphorus will block one mg of calcium from being absorbed. So a 100g serving of banana will need 17mg of extra calcium provided by other foods before it will be considered "safe".High Sugar Content
Bananas are very high in sugar. Roughly 12% of a banana's weight is sugar, which is why they a favorite food for many animals. Unfortunately, too much sugar causes issues in bearded dragons including mouth decay and obesity. If bananas were safe to feed to beardies, we would only recommend using them as a treat due to their high sugar content.
