Looking at the nutrition label, sugar content and sugars are listed separately under the carbohydrate breakdown.

Composed of 糖(とう) (sugar) and 類(るい) (type, class). Refers to sugars as a chemical or nutritional category, not to table sugar in everyday cooking.

Usage

Most commonly encountered on Japanese food labels and in health-related contexts. Japanese nutrition labels distinguish between 糖質(とうしつ) (total digestible carbohydrates minus fiber) and 糖類(とうるい) (simple sugars like glucose and sucrose). Products marketed as '糖類(とうるい)ゼロ' (zero sugars) may still contain sugar alcohols or artificial sweeteners.
