Correct arithmetic is only one part of accuracy
A calculator can add published ingredient values correctly without knowing the exact nutrition of the meal in your hands. Its result depends on three things: the source records, the portion assumptions and the ingredients actually served. Our tests check the arithmetic and state handling; they do not chemically analyze restaurant meals.
The underlying official PDF available during our October 29, 2026 review carries an October 2024 imprint, despite a March 2025 filename. We retain that distinction. A review date is a record of our source check, not evidence that every recipe is current to that day.
Zero, unknown and less than are different
A reported zero is a numeric source value. An unknown nutrient is missing information. A “less than 1 g” label describes a bound, not an exact zero or one. Our data model represents these separately so missing information cannot silently turn into a deceptively precise total.
For example, a soft taco tortilla has fiber reported as less than 1 g. Three tortillas therefore contribute less than 3 g before the fillings are added. If the fillings contribute 8 g exactly as reported, the displayed total is 8–<11 g. That range preserves the source uncertainty.
Rounded records should stay separate
Published nutrients are rounded. Two rounded 2 oz portions do not always equal a separately labeled 4 oz side in every nutrient column. We keep distinct queso topping and side records for this reason. Calories are also summed directly instead of reconstructed from rounded macro grams.
The calorie-share ring uses protein × 4, carbohydrate × 4 and fat × 9 as a visualization. Those relative macro energy estimates can differ from the published calorie total. The ring is an explanatory view, not an alternate source for meal calories.
What we leave out
We do not infer a full-size quesadilla recipe from a tortilla and an arbitrary amount of cheese. We do not assign standard chicken values to a seasonal chicken recipe, and we do not claim to know every location’s beverage availability. Unsupported items are explained rather than assigned invented numbers.
Allergen information also has limits. A basic ingredient reference cannot guarantee the absence of preparation cross-contact. Use the official allergen page, ask staff about your order and treat this calculator as an informational tool rather than an allergy-safety decision system.
Use the same documented ingredients in your own meal.
Put the example to work: open the meal builder, browse ingredient nutrition or compare published portions.
