Where Do the Calories in a Banana Come From?

Most of the calories in banana come from carbohydrates.

With 22.8g of carbs per 100g , banana contains more carbohydrate than fruits such as strawberries or watermelon, while remaining naturally very low in fat.

Protein contributes only a small amount, with approximately 1.1g per 100g , so banana should not be considered a high-protein food.

Sugar and Fiber in Banana

A 100g serving contains approximately 12.2g of naturally occurring sugars and 2.6g of dietary fiber .

The sugar found in a plain banana occurs naturally within the fruit. It is different from added sugar used in sweetened foods and drinks.

Looking at sugar together with fiber and total carbohydrates gives a more complete picture of the fruit's carbohydrate content than focusing on sugar alone.

How Much Potassium Is in a Banana?

Bananas are well known for potassium, and 100g provides about 358mg of potassium .

Potassium is an essential mineral involved in normal muscle, nerve, and fluid-balance functions.

Banana also provides smaller amounts of vitamin C, calcium, and other micronutrients.

Does Banana Size Change the Calories?

Yes. The values on this page are based on 100g , not one banana.

Bananas naturally vary in size, so a small banana will generally contain fewer calories and carbohydrates than a large banana simply because the edible portion weighs less.

Using nutrition per 100g gives you a consistent reference without assuming that every banana is the same size.
