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.

This label falls in the fourth Nutri-Score band. The model arrives there when its penalty terms — energy density, sugars, saturated fat, sodium — carry more weight in the calculation than the fibre, protein and produce content it credits. The band covers a wide span of the points scale, so position within it is not visible from the letter alone. The grade reflects the declared nutrition panel and is unrelated to the additive ratings listed below, which come from different bodies applying different criteria.

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.
