How FoodScan decides

FoodScan shows the grade the experts published, shows why, and is honest about what it does not know. This page explains the method, the checks, and the limits.

• The grade is the official Nutri-Score
• Reasons shown only when the maths adds up
• Impossible values put the grade on hold
• Better means a real, named improvement
