Polyols and sugars occupy different categories on an EU label
Read carbohydrate, sugars, and polyols without treating the three rows as independent totals.
A food can list a polyol ingredient while reporting a small sugars value. That is not automatically a contradiction. The first step is to use the definitions and panel structure for the market, then distinguish an ingredient name from a reported nutrient category.
Use the EU category boundaries
In EU nutrition-label definitions, carbohydrate includes polyols, while sugars excludes polyols. Annex XV shows sugars and polyols as subdivisions under carbohydrate. See Annex I and Annex XV of Regulation (EU) No 1169/2011. The rows therefore are not three independent quantities to add together.
The FDA also explains sugar alcohols as a carbohydrate category in its sugar-alcohol factsheet. Keep market-specific presentation rules separate when comparing a US panel with an EU declaration; do not assume the visible rows will be identical.
Try a hypothetical panel
Suppose an invented EU nutrition declaration reports 60 g carbohydrate per 100 g, with 2 g sugars and 35 g polyols. The printed carbohydrate total remains 60 g. Adding 60, 2, and 35 would count subdivisions again and give a misleading 97 g.
Subtracting the two displayed subdivisions leaves 23 g by arithmetic, but that remainder is not a full laboratory identification of every carbohydrate in the product. It is simply what remains after subtracting the reported values in this example. Keep that limitation visible rather than naming an undisclosed ingredient for the remainder.
Match the ingredient to the right task
If the ingredients name a particular polyol, copy the complete name. The ingredient list identifies what is declared; the nutrition rows provide quantities at their stated level. A polyols total does not necessarily break down the amount of each individual polyol if more than one is present.
For a useful comparison, record the market, per-100-g or serving basis, carbohydrate total, sugars, and any declared polyols value. Leave an absent polyols quantity unavailable rather than assuming zero. Do not estimate it from a product description or the length of the ingredient list.
This approach resolves the apparent mismatch without assigning a health score or making a dietary recommendation: the label categories have different definitions, and each number must stay attached to the category it actually describes.
