How we judge this, and the sources
The answer comes from the food's composition, not from opinion: its Nutri-Score grade on the open 2023 algorithm, a traffic light for sugar, salt, saturated fat and fiber per 100 g, and the share of daily reference amounts in a typical serving (for salt, sugar, fiber and vegetables, those of the WHO). It rates the food's nutrient profile; it is not medical advice. Formulas, thresholds and every source are on the methodology page; last checked against the sources on November 1, 2026. The short food description was written by our language model (AI) — how we check the text.
