Nutri-Score is a front-of-pack nutrition label that rates food products from A (healthiest) to E (least healthy). It's widely used across Europe and helps consumers make informed dietary choices at a glance.

What is the NOVA classification?

The NOVA classification assigns a score from 1 to 4 depending on how much a food is processed. 1 means unprocessed/minimally processed foods, while 4 indicates ultra-processed food and drink products.

Is the allergen data reliable?

The allergen data is derived from product labels uploaded by contributors. While extensive, you should always double-check physical packaging for severe allergies as formulations can change.
