What changes the estimate most?
This is a standardized USDA survey-food profile, not a measurement of every preparation. Actual nutrition can change with portion size, fat level, brand or formulation, added flavors or sweeteners.
Food estimates can be sensitive to portion weight, preparation, ingredient ratios, and additions that are difficult to judge from appearance alone.

How we estimated this
Traceable back to the source record
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.
