Energy comes from USDA nutrient 1008. Salt is calculated as sodium × 2.5, with unit conversion to grams. It is not a separately measured salt value.
Preparation
This is a raw banana record, not a measurement of every variety or stage of ripeness. Ripening changes starch and sugar composition; this table cannot quantify that change for your fruit. For banana bread, calculate the recipe including flour, fat and sugar. For dried bananas or fried banana chips, use the matching product label rather than this raw-fruit record.
Logging this food
USDA serving weights here are edible weights: small 101 g, medium 118 g and large 136 g, about 90, 105 and 121 kcal respectively. A medium banana is about 4.2 oz peeled. If your banana weighs 150 g without the peel, calculate 150 times 89 divided by 100, or about 134 kcal. Do not count the peel as food.
Swaps and alternatives
Compare portions as well as per-100 g values. The raw apple reference is 52 kcal per 100 g, versus 89 for banana, but the usual serving weights differ. Neither fruit needs to be excluded because of one number. For a smoothie, count the actual edible fruit plus milk, yogurt, nut butter and any other ingredients.
Questions about a banana
How many calories are in 2 bananas?
About 210 kcal for two medium bananas, with roughly 46 g of carbohydrate. Two small ones are about 180 kcal.
How many calories are in a large banana?
About 121 kcal for a large banana (20–23 cm, ~136 g peeled), and about 135 for an extra-large one over 23 cm.
How many calories are in a banana without the peel?
The figures already describe peeled fruit: the medium serving is 118 g and about 105 kcal. Weigh the peeled banana when possible. The proportion of peel varies, so a fixed deduction from the whole weight can only be an estimate.
Does a ripe banana have more calories?
This raw-banana reference gives 89 kcal per 100 g without a separate ripeness adjustment. Ripening changes starch and sugar composition, but one database record cannot measure the change in a particular fruit. Use the edible weight and a suitable record; dried or fried bananas need a different entry.
