Nutrition builder

Add exact menu items and total their published per-serving nutrition. Products without a checkable source are not offered, and a nutrient total disappears if any selected item is missing that value.

174 sourced item profiles19 researched brandsPer servingNo estimates

Changing the brand or market refreshes the sourced item list. Unsupported products stay hidden.

19 of 35 brands publish per-serving nutrition we can verify at the source. The rest are excluded rather than estimated - Where a brand is silent, so are we.

Add published servings without filling evidence gaps

The builder is intentionally strict: an item appears only when its market-specific nutrition profile can be tied to a publisher and source. That produces fewer choices, but a more honest total.

  1. Choose brand and marketRecipes and serving sizes can change by country, so nutrition profiles stay market-specific.
  2. Select exact itemsEach checked item contributes one published serving in the preparation shown.
  3. Read complete totalsA nutrient is totaled only when every selected item publishes a value for it.

What a displayed total means

  • Every selected item has a numeric value for that nutrient.
  • Values are added as published for one serving of each item.
  • The source list identifies the exact products and preparations used.

What a blank total means

  • At least one selected profile does not publish that nutrient.
  • Blank does not mean zero and is never treated as zero.
  • No value is borrowed from another country or similarly named product.

Why the available menu is deliberately limited

Nutrition varies with recipe, portion, bread, sauce, toppings and preparation. The builder includes a product only when the database holds per-serving figures with a publisher and source URL for that exact market item. It does not infer values from a similar sandwich, convert a per-100g panel without a published serving weight, or fill a missing nutrient with zero.

Each selection represents one published serving. If you eat two servings, customize the product, omit ingredients or choose a different size, the displayed total no longer describes the consumed meal exactly. Sodium and salt are preserved as the source reports them; they should not be casually added together as though they were the same unit.

Use this as label-reading support, not individualized medical advice. The builder does not assess allergens, dietary suitability, nutrient targets or health conditions. Follow the restaurant’s current allergen information and consult a qualified professional when dietary decisions are medically important.

Nutrition builder questions

Why are many restaurant items unavailable?

They do not yet have an exact, source-linked per-serving profile in this database. The tool stays silent rather than displaying a generic or inferred estimate.

Why does a nutrient disappear after I add an item?

One of the selected items does not publish that nutrient. A partial sum would look like a meal total while omitting part of the meal, so the builder withholds it.

Are customizations included?

No. The result describes the named preparation and serving in the cited source. Different bread, cheese, sauces, toppings, size or preparation can change the figures.
