Check nutrition claims against GB/EU and US rules
check_claimFor a RAW or minimally-processed whole food, report which nutrition claims ("source of iron", "high in vitamin C", "high fibre") the published data supports under GB/EU rules (15%/30% of NRV per 100 g, Reg. 1924/2006) and US rules (10-19%/20% of DV per RACC, 21 CFR 101.54) — and, uniquely, flag where that answer DEPENDS ON WHICH national food-composition table was used, since the eleven tables reconciled here disagree on the same food by a median of 1.63x. Applies to claims wherever they appear, including websites and advertising (Reg. 1924/2006 Art. 1(2)), not only packaging. NOT valid for cooked or manufactured products — their composition depends on recipe and processing. Screening only: under Art. 5(1)(b)(i) the nutrient must be in THE FINAL PRODUCT, so a supported claim still needs an analysis of the producer's own produce. Never treat this as a way to pick a source that qualifies.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| food | Yes | Food slug or name — e.g. "banana", "brazil-nuts". | |
| market | No | Which rules to apply. Default "both" — the divergence is usually the point. | |
| nutrient | No | Optional: check one nutrient only, e.g. "potassium". | |
| preparation | No | Must be "raw" (the default). This tool holds raw and minimally-processed commodity data only and REFUSES anything else, because cooking changes composition in both directions — vitamin C and folate are destroyed while minerals concentrate as water is lost. If the food you are asking about has been cooked, juiced, or made into a product, do not call this tool: its answer would not describe your product, and a nutrition claim is a legal statement about the product actually sold. | |
| only_permitted | No | Optional: return only claims the data supports, dropping the ones that fail. |
