Scoring methodology · Packaged foods

How we score packaged foods

Every food product is evaluated against 4 rules, worth a total of 90 points. Your score is the percentage of points the product earns on what we actually know about it.

Active version: 2026.06.04

Quality score

Earned out of possible

Each rule contributes points up to a known maximum. We sum them, divide by the total possible, and that's the headline number on the product.

Unknowns

No data earns no points

If we couldn't verify an attribute, that rule earns zero. Brands aren't rewarded for non-disclosure, and we don't fill the gap with a guess.

Found something wrong?

Scoring is a function applied to evidence. If you think a rule fired on the wrong evidence, the per-product breakdown shows the source for every contribution — each one is challengeable. The methodology itself is version-controlled and evolves in public.
