Values for banana vary by brand and how it is cooked. Check the pack. General information, not medical advice.

The peeled weight

The serves are for the peeled fruit. A banana in its skin weighs about a third more, so weigh it after peeling if you want to be exact.

Ripeness

A ripe banana tastes sweeter, but the calories barely change. The starch turns to sugar as it ripens, and the total stays close.
