The Core Calorie Count: Breaking Down the Banana and Peanut Butter
To find how many calories are in a banana with peanut butter, calculate each part separately. The calorie count varies with the banana's size and the amount and type of peanut butter. Most estimates use a medium banana and a 2-tablespoon serving of conventional peanut butter.
Banana Calorie Breakdown
Banana sizes differ, which affects calorie counts. Here's a general guide:
- Extra Small (under 6 inches): Approx. 72 calories
- Small (6–7 inches): Approx. 90 calories
- Medium (7–8 inches): Approx. 105 calories
- Large (8–9 inches): Approx. 121 calories
- Extra Large (over 9 inches): Approx. 135 calories
Bananas primarily provide carbohydrates, especially natural sugars, and are a good source of dietary fiber and potassium.
Peanut Butter Calorie Breakdown
Peanut butter's nutritional content is consistent, but differences exist between varieties. A standard 2-tablespoon (32g) serving is the common metric.
- Conventional Peanut Butter (2 tbsp): Approx. 190 calories
- Natural Peanut Butter (2 tbsp): Approx. 190 calories, often with no added sugar
- Powdered Peanut Butter (2 tbsp reconstituted): As low as 50 calories, due to fat removal
Peanut butter is high in healthy monounsaturated and polyunsaturated fats, as well as protein. This combination makes the snack satisfying.
Total Calorie Estimates for Different Combinations
