How accurate are these numbers?
The values on this page are reference averages from the USDA FoodData Central database (SR Legacy release), measured on samples of fish sandwich as sold and prepared in the United States. Your portion will differ: produce varies by variety and ripeness, meat by cut and trim, and anything cooked by the fat and water it gained or lost.
For most foods the per-100 g figure is reliable to within about 10%. The larger uncertainty is almost always the weight of what is on your plate and the cooking fat you cannot see — the two things worth checking before you worry about the database.
