How we estimated this
This profile uses FoodData Central Survey Foods (FNDDS). It reports the source serving, calculates the 100-gram comparison from the same record, and scales household portions by their listed gram weights.
About the serving label: USDA describes the underlying portion as “Typical reported amount.” We display it as “USDA reference amount” to make clear that it is a database comparison point—not a suggested portion or a claim about what most people should eat.

It does not reconstruct every possible recipe or infer your plate’s weight. Preparation and recipe differences belong in the uncertainty explanation, not hidden decimal places.
