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 is among the longer ones in this catalogue. A component set this wide means the screen returns many individual ratings, and the composite accumulates a large number of small contributions instead of turning on a handful of entries. At this length the per-component table below is substantially more informative than the single figure, because the figure compresses a great deal of variation into one number.
