Rounded. Carbohydrates are total carbohydrate, fiber included, as on a US Nutrition Facts label; salt is sodium × 2.5. Table licenses are on the data sources page.

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.

Swaps for rusks
Rusks have a fair amount of sugar (9.8 g per 100 g), a fair amount of saturated fat (2.1 g per 100 g) and a fair amount of salt (0.4 g per 100 g), but our database has no same-category swap that fixes this noticeably at the same calories and is a full grade better.
