Bananas are pretty easy to digest and it usually takes a round 1 hour to 2 hours at most to fully digest a banana.
If I eat a banana I'm usually needing to poop within an hour after eating the banana so I would say for me personally it takes an hour to digest one banana.
If I eat more than 1 banana it can take a bit longer to digest the rest of the other bananas.
Bananas are a good source of potassium and carbohydrates which is pretty easy to digest and healthy for our health.
Bananas make a great healthy snack and can fill your stomach up enough to get you through till lunch or dinner time.
