# Shelf Check

> Shelf Check ranks UK supermarket products within each aisle by what is printed on the label: nutrition per 100g, UK front-of-pack traffic lights, Nutri-Score, NOVA processing group and additives. It is free, independent and never sponsored. Product data comes from Open Food Facts under the Open Database Licence (ODbL).

- Coverage: 20,977 products sold in the United Kingdom, across 22 aisles.
- Freshness: data snapshot of 7 October 2026. Every page states its snapshot date.
- All pages below are plain HTML that needs no JavaScript, with schema.org JSON-LD (ItemList of Product with NutritionInformation per 100 g).
- Method: values are per 100 g as recorded from the pack. Traffic lights use the UK Department of Health thresholds per 100 g (fat 3/17.5 g, saturates 1.5/5 g, sugars 5/22.5 g, salt 0.3/1.5 g). Rankings only include products whose label adds up (energy roughly matches fat, carbohydrate and protein; sugars not above carbohydrate) and allow at most two products per brand in each top 10. Ultra-processed means NOVA group 4 as assigned by Open Food Facts.
- Licence and credit: reuse is welcome. Credit Open Food Facts (ODbL) and link to https://shelfcheck.food. Brands cannot pay to rank.
- Limits: Open Food Facts is crowd-sourced, so labels can be out of date or wrong, and coverage is a large sample, not a census. Do not rely on it alone for allergy decisions.

## Optional

- [Interactive app](https://shelfcheck.food/): rank any aisle by any nutrient and filter out allergens or ingredients. Needs JavaScript. Deep links: /#c={data-slug}&s={metric}&p={barcode}, where metric is one of protein, sugar, salt, satfat, fat, fibre, kcal, protPer100kcal, additives.
- Raw data: https://shelfcheck.food/data/{data-slug}.json holds the Open Food Facts records each aisle is built from (data slugs: yogurts, breakfast-cereals, granolas, protein-bars, breads, crisps, biscuits, cheeses, pizzas, meals, sausages, bacon, hams, plant-based-milk-alternatives, hummus, dips, pasta-sauces, pestos, fresh-pastas, dried-pastas, butters, margarines). Shelf Check's cleaning and ranking are applied on top of these.
