When a banana gets bruised, does the nutritional content of the bruised area change?
gpt
Once a banana starts to over ripen - be it from time or from some sort of damage to the peel - the starches start to break down into sugars. That's what makes brown, or bruised, bananas taste sweeter. You can eat a brown or bruised banana so long as you enjoy a sweet banana, but when they start to get darkened or blackened then they usually reserved for baking pies or something like that. 

Does the nutritional content change? Yes, starches break down into sugars as the fruit gets bruised or ripens.
