    The amount in a reference apple

    USDA’s SR Legacy 2018 entry for raw apples with skin lists 4.6 mg vitamin C per 100 g. Its medium apple weighs 182 g, giving about 8.4 mg. A 149 g small apple works out to 6.9 mg and a 223 g large apple to 10.3 mg. These are reference edible portions, not weights including a discarded core. [1]

    Match the food description before using the number

    This entry includes the skin and concerns raw apple. It does not describe peeled apple, applesauce, dried apple or fortified juice. The source is the final 2018 SR Legacy release; cultivar, storage and the actual fruit can differ from its reference composition. Weighing the portion improves the serving estimate but does not make the nutrient value a laboratory measurement of that apple. [1]

    Scaling a hypothetical snack

    For a hypothetical 150 g portion matching that food description, multiply 4.6 by 1.5: about 6.9 mg vitamin C. Two identical portions would provide about 13.8 mg. Count the grams eaten rather than assuming that every item called one apple has the same size. [1]
