Measuring banana

The record is raw banana, at 89 kcal per 100 g. USDA lists the skin as refuse and gives nutrient values for the edible part, so weigh the peeled fruit when you use grams. Sizes have separate rows, and a medium banana is 118 g. Cups differ too: a cup of mashed banana holds more grams than a cup of sliced banana, and the page shows the grams for each. Dried bananas, banana chips, banana bread and smoothies are different products and are not covered. Ripeness is not a separate row.

Common questions

How many calories in a medium banana?

A medium banana is 105 kcal at 118 g, from the USDA raw banana record. Small and large bananas have their own rows in the table.

How many calories in 100 g of banana?

Raw banana is 89 kcal per 100 g. Weigh it without the peel, because the record covers the edible part.

How many calories in a cup of sliced or mashed banana?

A cup of mashed banana weighs more than a cup of sliced banana, so it has more calories. The table lists both cup rows with their grams. Pick the row that matches how you measured.

Does the peel count in banana calories?

No. USDA lists the skin as refuse, and the nutrient values are for the edible part. Weigh the banana peeled before you compare it with the gram rows.
