What the carbs are made of
Of the 27.1 g of carbs in a medium banana, 2 g is fiber and 18.6 g is total sugars. The remaining 6.5 g is starch and other carbohydrates. USDA reports total sugars for this food. It does not split natural from added sugar, so check the label of packaged versions.
Raw, cooked and other forms
Per 100 g, the 4 USDA entries below range from 20.1 g in bananas, overripe, raw to 32.4 g in banana, baked.

How we calculate: every amount is the USDA value per 3.5 oz (100 g) scaled to the gram weight USDA lists for that measure. 1 oz = 28.35 g and 1 lb = 453.6 g. Daily Values: FDA, 21 CFR 101.9, for adults and children 4 years and older. A dash (—) means USDA reports no value. How we verify.
