How scoring works
The clean score reads only the ingredient label. Up to 60 points come from the 9 additive groups we check: each group not on the label earns its share, and a group named only in a "may contain" note earns half. Up to 25 points come from an organic claim we have confirmed. Points that do not apply to this kind of food are left out and the rest is scaled to 100.
This product: 8 of 9 groups not on the label. No confirmed organic claim.
