Read sugars as part of carbohydrate on an EU label
Use an EU-specific example to avoid adding sugars twice or calling every remaining carbohydrate gram starch.
On an EU nutrition panel, the sugars line describes a component of carbohydrate. It should not be added to the carbohydrate figure as another independent total. Read the category labels before using the numbers in a recipe or comparison.
The EU food information regulation defines sugars and carbohydrate in Annex I and shows their presentation in Annex XV. This article keeps to that EU framework rather than assuming every country's carbohydrate declaration has identical scope.
Follow one hypothetical label
Imagine a product lists 30 g carbohydrate, of which sugars 8 g, per 100 g. A 50 g portion has an estimated 15 g carbohydrate and, within that amount, 4 g sugars. Adding 15 and 4 would double-count the sugars and incorrectly report 19 g carbohydrate.
The same relationship applies to the original column. Thirty grams is the declared carbohydrate total; thirty-eight is not. In a worksheet, place the sugars entry under a clearly marked component heading instead of including it in a sum of all nutrients.
Do not give the remainder a name without evidence
Subtracting 8 from 30 produces a 22 g remainder in the per-100-g example. That subtraction alone does not establish 22 g starch. Other carbohydrate categories can be relevant, including polyols, and the label may not separately quantify them.
For the same reason, a calculated remainder should not be described as naturally occurring sugar or added sugar. Those are different questions from the relationship between total carbohydrate and the sugars row.
Compare both categories explicitly
Suppose a second fictional product declares 25 g carbohydrate and 10 g sugars per 100 g. Compared at equal weight, it has 5 g less declared carbohydrate but 2 g more sugars. Neither row alone describes the whole nutritional profile.
At a 40 g portion, the first product gives 12 g carbohydrate and 3.2 g sugars. The second gives 10 g carbohydrate and 4 g sugars. Keeping the categories separate preserves the distinction as portions change.
When importing a US or other-market record, retain the original market and full nutrient names. Do not merge differently defined carbohydrate categories automatically. This is a label-reading and arithmetic exercise; it does not provide a carbohydrate intake target or guidance for managing a medical condition.
