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.
Plain enriched
Selected reference; the source description also groups onion, poppy and sesame examples.
Whole-grain
Use the matching whole-grain label or record.
Sweet or flavoured
Use the product label because ingredients vary.
With a spread or filling
Add cream cheese, butter, egg, meat or other fillings separately.
PRACTICAL CONTEXT

Keep bagels sealed according to package directions.
After opening or cooking

PHOTO LOGGING
How to log plain bagel 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: Bagels, plain, enriched, without calcium propionate (includes onion, poppy, sesame).
- 02
Use edible grams. Calories are scaled from the selected per-100-g record; named portion weights come from the same local USDA record.
- 03
Log oil, sauce, sweetener, salt and recipe ingredients separately.
- 04
Use a separate record when preparation changes the food state.
