How the calculation works

Calculated net carbs = total carbohydrate − dietary fiber. For this USDA record, that is 32.3 g − 1.2 g = 31.1 g per 100 g. Net carbs is a planning convention used on this site; it is not a separate USDA nutrient field or a regulatory nutrition-label value. This calculation does not automatically subtract sugar alcohols.
