iAlacarte does not estimate from memory: nutritional values, allergens, health indicators and wine profiles rely on public reference standards, imported and verified. This page names them, along with their scope and limitations.
For a restaurant dish, the listing is built up: each recipe ingredient is matched to a line in these tables, weighted by its class (oil, sauce, grated cheese, topping…) and converted to a serving. See Nutritional values in restaurants.
The allergens shown are the fourteen listed in Regulation (EU) No 1169/2011, plus buckwheat. Every allergen must be supported by a recipe ingredient; an allergen without supporting evidence is removed.
Health indicators (pregnancy-compatible, low salt, nightshade-free, low histamine…) come from a criteria register in which each signal cites its authority: Regulation (EC) No 1924/2006 for claims, ANSES and Santé publique France recommendations for pregnancy, EFSA, IARC, the SIGHI list for histamine, APG classification for nightshades, Sydney glycaemic index tables, and Monash for FODMAPs. When a measured value contradicts an indicator, the indicator is removed.
When a menu names a dish without listing its ingredients, a reference recipe may be suggested: a dictionary of classic dishes, supplemented by an extract from the public RecipeNLG corpus. A recipe whose meat or fish contradicts the dish name is rejected, and a recipe suggested for an add-on without a description is deleted along with everything derived from it.
