How is the score built?

Open the methodology note

Nutrition score measures nutrient profile only. Processing, environment, label quality, and data confidence stay separate so missing data or formulation signals do not silently change nutrition quality.

The data is broad and consistent. The interpretation is likely to remain stable.
