Screening model notes

How Nutri-Score, NOVA, and list length read this record

Within the four-tier shelf-label framework this site publishes, the composite for this product falls in the highest band. That band is defined by a threshold on the derived score alone: it is where labels land once components carrying caution-or-worse registry ratings contribute little or nothing to the deduction. The band is a summary of what the screened registries return for the components that were parsed, so it inherits their coverage gaps — a component absent from both registries neither raises nor lowers the figure. The threshold and the weighting behind it are set out on the methodology page.

The Nutri-Score algorithm returned its second band for this label. That grade typically describes a nutrition panel whose favourable components register clearly in the model without fully offsetting its energy or sodium terms. Because the calculation is a single points balance rather than a set of independent thresholds, a strong fibre or protein figure can lift a panel into this band even where one penalised nutrient sits high. The grade summarises the declared panel alone and carries no information about the additive ratings screened below.

The declared list parsed into a small number of components. On a short list the registry screen covers close to everything the packaging declares, and any single matched component accounts for a correspondingly large share of the composite. Short lists also leave less room for parsing error, since there are fewer separators and qualifiers for the extraction to resolve.
