Serving and food-state notes

How this answer was calculated
For foods without sugar alcohols, this site uses net carbs = total carbohydrate − dietary fiber. “Net carbs” is a tracking convention, not a separate nutrient on the standard U.S. Nutrition Facts label.
Per 100g, the record contains 16.8g total carbohydrate and 1.5g fiber. Multiplying by 2.10 gives 35.3g total carbs and 3.2g fiber; the displayed difference is 32.1g net carbs.
