Nutrition Label Scanner

How do I use the label scanner?

• Barcode: choose Enter barcode, type the number printed under the barcode on the pack and tap Look up product. This returns real data from Open Food Facts.
• Photo: choose Upload photo and add a clear picture of the nutrition panel. Real AI label reading is being connected, so photo results are currently demo results with a clear label.

What do the barcode scores mean?

For barcode lookups, every number comes from the product's Open Food Facts record, per 100 g:

• Health score: based on the product's Nutri-Score grade. A = 90, B = 75, C = 60, D = 45, E = 30, and 55 when no grade is available.
• Sugar level: low at 5 g or less per 100 g, moderate up to 22.5 g, high above 22.5 g. These are the UK front-of-pack traffic-light thresholds.
• Simplicity score: based on the NOVA processing group. Group 1 (unprocessed) = 95, group 2 = 75, group 3 = 55, group 4 (ultra-processed) = 30.
• Protein quality: good when the product has 10 g of protein or more per 100 g.
• Additives: up to 8 listed additives, such as E-numbers.

Which warnings can it show?

• High in sugar: more than 22.5 g per 100 g.
• High in salt: more than 1.5 g per 100 g.
• High in saturated fat: more than 5 g per 100 g.
• Ultra-processed food: NOVA group 4.
• Contains several additives: more than 4.
• Allergens declared in the product record.

The WHO advises keeping salt below 5 g a day and free sugars below 10% of daily energy, so these warnings help you spot products that use up a lot of that budget.

Limitations

Open Food Facts is a free, open database built by contributors. Some products are missing, and some records are incomplete or out of date, so if a barcode is not found you will see a message. Recipes also change. Always check the pack itself, especially for allergens.
