Orange Varieties: Nutrition Comparison (Raw, Per 100g)
Orange calories: whole fruit and juice are different entries
The cited USDA reference lists raw orange at 47 calories per 100 grams. For a whole orange, use the edible segments rather than including the peel in the serving weight.
How to log a U.S. serving
Orange juice is not calculated by multiplying the weight of a whole orange. Commercial juice may have a labeled eight-fluid-ounce serving, while home-squeezed juice depends on how many oranges were used and how much pulp remains. Use the bottle label or a juice-specific source.
When to use another entry
For common U.S. products such as canned mandarins, fruit cups, and frozen juice concentrate, check whether the product is packed in water, juice, or syrup. The raw-orange value does not include the packing liquid or added sugar.
