Nutrition facts per 100g + common serving sizes
Banana calories: use edible weight and actual ripeness
The USDA reference is 89 calories per 100 grams of raw edible banana. Do not include the peel in the weight. A banana sold as small, medium, or large is only a rough size category, so weighing the peeled fruit gives a clearer result.
How to log a U.S. serving
Ripeness changes texture and sweetness as starches change, but it does not justify assigning a dramatically different calorie value without a matching source. For an everyday U.S. breakfast or snack, record the banana separately from peanut butter, yogurt, granola, or protein powder.
When to use another entry
A smoothie also needs an ingredient-by-ingredient total. Milk, juice, nut butter, sweeteners, and a second banana can contribute more than the fruit used as the starting reference.
