How to use the Food Nutrition Scanner

  1. Search by name — type any food and select from the autocomplete list. Results come from the USDA FoodData Central database (140,000+ foods including branded products).
  2. Enter a barcode — type the EAN/UPC number from the packaging, or use your device camera to scan it.
  3. Enter manually — useful for fresh produce or home cooking. Enter calories and macros per 100g.
  4. Adjust serving size — all values scale automatically when you change the portion.
  5. Read the verdict — the WorthIt badge tells you whether the food is a good regular choice based on its Nutri-Score and NOVA level.

Frequently asked questions

What is Nutri-Score?

Nutri-Score is a nutrition label (A to E) that summarises a food's overall nutritional quality. A and B are the healthiest choices; D and E indicate poor nutritional quality due to high fat, sugar, or salt and low fibre, protein, or fruit content.

What is the NOVA food processing classification?

NOVA classifies foods by how processed they are — not by their nutrient content. NOVA 1 (unprocessed), NOVA 2 (culinary ingredients like oil or flour), NOVA 3 (processed foods like tinned beans), NOVA 4 (ultra-processed foods with many additives). Research links NOVA 4 foods to higher risks of obesity, diabetes, and cardiovascular disease.

Is the food data accurate?

It depends on how you look up the food. Text search uses USDA FoodData Central — a public database maintained by the US Department of Agriculture with 140,000+ foods, including branded grocery products. Barcode scanning pulls from Open Food Facts, a crowdsourced database with 1M+ products that includes Nutri-Score and NOVA classification. Both sources are reliable — USDA data is government-verified, and Open Food Facts is the same database used by apps like Yuka. Fresh produce and home cooking are best entered manually.

What do the daily value percentages mean?

Each macro shows what percentage of the daily reference value one serving provides, based on a 2,000 kcal diet. Values differ slightly between UK/EU and US references — select your region at the top of the tool. Going over 100% for calories, fat, or sugar is worth watching; going over 100% for protein or fibre is fine.

Can I check any food — including supermarket own-brands?

Yes. Open Food Facts includes own-brand products from Tesco, Sainsbury's, Lidl, Waitrose, and most major UK and EU supermarkets. Search by product name or scan the barcode on the back of the packaging.
