The Size and Weight of an 80g Banana
To visualize what 80g of banana looks like, think of an extra-small sized fruit, typically measuring under 6 inches in length. However, it's important to clarify if the weight refers to the fruit with or without the peel. Standard nutritional measurements for fruit, including those from databases and health organizations, are typically based on the edible portion only. Therefore, when we discuss the nutritional content of 80g of banana, we are referring to the flesh alone. In terms of preparation, this could also be a medium-sized banana sliced into rounds or a portion of a larger one. For a practical approach, using a kitchen scale is the most accurate method for precise calorie or carbohydrate counting, especially for those tracking their intake for specific health goals.
The Nutritional Profile of an 80g Portion
An 80g portion of raw, peeled banana offers a nutrient-rich package for a relatively low caloric investment. The exact figures can vary slightly based on ripeness, but reliable sources provide a clear picture of what this serving provides.
Macronutrient Breakdown
The majority of the calories in a banana come from carbohydrates, predominantly natural sugars and fiber. A detailed breakdown includes:
- Calories: Approximately 71 kcal.
- Carbohydrates: Around 18 grams, of which about 10g are sugars and 2g are dietary fiber.
- Protein: Approximately 1 gram.
- Fat: A negligible amount, less than 0.5 grams.
Vitamins and Minerals
Beyond the basic macros, 80g of banana is an excellent source of specific micronutrients crucial for body function.
- Potassium: Containing roughly 286mg, or about 6% of the Daily Value, this mineral is vital for regulating heart function, fluid balance, and blood pressure.
- Vitamin B6: Providing a substantial 23% of the Daily Value, Vitamin B6 is essential for brain development, metabolism, and immune function.
- Dietary Fiber: With about 2g of fiber, this portion supports digestive health and promotes feelings of fullness.
Is an 80g Banana a Healthy Serving Size?
Yes, an 80g portion is considered a standard healthy serving size and contributes to your daily fruit intake. Its high fiber content can aid weight management by increasing satiety. Furthermore, its carbohydrate content and natural sugars make it an excellent source of energy, particularly useful before or after exercise.
Ripeness and Nutritional Impact
For those monitoring sugar intake, it is relevant to consider the banana's ripeness. Unripe, green bananas are higher in resistant starch, a form of carbohydrate that acts like fiber and can help moderate blood sugar levels. As the banana ripens and turns yellow, this resistant starch converts into natural sugars, increasing the overall sugar content. For general health, both are beneficial, but unripe bananas may be a better option for those concerned with blood sugar spikes or looking for the benefits of resistant starch.

Potential Considerations
While bananas are a healthy food, it is important to consume them as part of a varied diet. For individuals with specific dietary restrictions, such as those with late-stage kidney disease who need to limit potassium, consultation with a healthcare professional is advisable. Additionally, those monitoring blood sugar levels may prefer less ripe bananas due to their higher resistant starch content.
The Role of Fiber
The 2g of dietary fiber found in an 80g banana plays a critical role in digestion and overall health. This fiber, especially the resistant starch in greener bananas, acts as a prebiotic, feeding the beneficial bacteria in your gut. This supports a healthy gut microbiome, which is linked to numerous health benefits. Regular fiber intake is also known to help regulate bowel movements and prevent constipation.
