Inside the source record
Source formulation behind this USDA record
USDA links this survey-food entry to 2 source inputs used to calculate the reference nutrition. Publishing those inputs makes the record easier to inspect and helps explain why two similarly named foods can have different values.
How to read this
2 listed components
The largest listed inputs by source weight are Eggs, Grade A, Large, egg whole, Salt, table. The order and weights below come from the standardized USDA formulation, so they offer context for this exact database entry.
100.3 g total listed input weight across the formulation.

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, recipe or brand, cooking fat, toppings and add-ins.
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.
