FOOD STATE MATTERS
How preparation changes the nutrition estimate
A reliable calorie entry should describe the food you actually ate—not merely a food with a similar name.
Ready-to-serve sauce
Selected reference.
Diluted dipping sauce
Log the complete recipe.
Sweetened sauce
Use its product label.
Recipe seasoning
Measure the amount added.
PRACTICAL CONTEXT
How fish sauce can fit different goals

Fibre check
The selected record lists 0 g fibre per 100 g.
Protein check
The selected record lists 5.06 g protein per 100 g.
Best logging move
Measure the sauce and use its label because sodium and formulation vary.

PHOTO LOGGING
How to log fish sauce more accurately
A food photo can suggest the ingredient, but it cannot always reveal exact weight, hidden oil or preparation details. These checks turn an image guess into a better estimate.
- 01
Match the exact reference state: Sauce, fish, ready-to-serve.
- 02
Use edible grams. Calories are scaled from the selected per-100-g record; named portion weights come from the same local USDA record, while explicitly labelled gram examples are calculated.
- 03
Log oil, sauce, sweetener, salt and recipe ingredients separately.
- 04
Use a separate record when preparation changes the food state.
