Banana Nutrition Facts: A Medium Fruit by Edible Weight

A banana is convenient to carry on a day that includes a walk, bike ride, or another cardio activity. Convenience, however, does not make every banana the same serving. This guide uses the USDA reference for one medium raw banana, with an edible weight of 118 grams. The peel is excluded. The numbers describe the fruit alone, not a smoothie, a banana bread recipe, or a snack combined with other ingredients. For that medium reference fruit, the calculated values are approximately 105 calories, 26.9 grams of total carbohydrate, and 3.1 grams of dietary fiber. Fiber forms part of total carbohydrate. These figures can help identify what the food contributes to a day's meals, but they do not tell you how much exercise it fuels or how many minutes of activity would offset it. Food intake and exercise do not need to be reduced to a one-for-one exchange. The source is USDA FoodData Central, SR Legacy, food 173944, “Bananas, raw.” Its nutrient values per 100 grams were multiplied by 1.18 to match the listed medium portion. Calories are rounded to the nearest whole number and carbohydrate and fiber to one decimal place. This calculation uses a single food entry consistently; it does not borrow the calorie value from one serving and the carbohydrate value from another. The word medium is a helpful description, but the gram weight is the clearer comparison basis. If your banana is noticeably smaller or larger, its nutrient amounts will differ from the card. Weigh the peeled fruit when you need a closer match. Using the weight of the whole banana would count the peel as though it were part of the portion. Ripeness and natural variation also mean that a generic database entry is an estimate, not an exact analysis of each fruit. On a cardio day, think about where the banana fits into your usual meals and what feels comfortable for you. This post does not prescribe a pre-workout timing window, an endurance fueling target, or a recovery formula. Those decisions depend on the activity and the person. A routine walk and a long training session are different contexts, and the nutrient figures alone cannot determine a suitable eating plan for both. If you add peanut butter, yogurt, cereal, or milk, count those ingredients separately when calculating the snack. Blending a banana with several other foods does not leave the total equal to the banana's numbers. The finished recipe needs ingredient amounts, a total yield, and a defined serving. The plain fruit shown here keeps that distinction visible and avoids presenting an uncalculated combination as a verified meal. The useful takeaway is to identify the edible portion before using the nutrition values. Treat the banana as an ordinary food choice within a varied routine, rather than a guaranteed performance aid or weight-loss tool.
