Banana calories and nutrition facts
100 grams of banana contains 89 calories, with 1.1 g of protein, 22.8 g of carbohydrate and 0.3 g of fat. It provides 2.6 g of fiber and 12.2 g of sugar per 100 g. Most of its calories come from carbohydrate.
Bananas are the default portable snack for a reason: no packaging, no preparation, and a steady mix of quick and slow carbohydrate that makes them a favourite before training. Riper fruit tastes sweeter because starch converts to sugar as the peel spots — the calories barely change, only the flavour. If you log one, weigh it peeled: supermarket bananas swing from 90 g tiddlers to 150 g giants.
