This is not a complete diet, so the 1-100 rating does not apply to it. Read the recipe breakdown above as ingredient-quality context only.
Nutritional: declared analysis vs reference ranges

Transparency: what the label discloses
How much the manufacturer discloses, measured against the FEDIAF Code of Good Labelling Practice and Regulation 767/2009. Mandatory items dominate the weighting.

Safety: recall history
Recall and safety-notice history, time-decayed. This dimension is shown alongside the score and never feeds the headline number.
No recalls recorded in our database.
Evidence: what the brand claims, and what supports it
The claims made on the pack and product page, checked against the declared label. We record claims as stated; "consistent" means our stored label data supports the claim, "contradicted" means it conflicts with it. Functional claims are recorded but never scored.
100/100 · moderate — 1 checkable claim: 1 consistent, 0 contradicted.
Consistent with the label
- "no grains, fillers, artificial additives, or synthetic ingredients" — supported by the declared grain-free data.
9 further claims on file that we cannot check against the label.
