How Net Carbs Are Calculated
Net carbs are calculated by subtracting dietary fiber (and sugar alcohols, if present) from total carbohydrates: Net Carbs = Total Carbs − Fiber. For Sauerkraut: 4.3g − 2.9g = 1.4g net carbs per 100g.
Dietary fiber is subtracted because it passes through the digestive system without being absorbed as glucose. It does not raise blood sugar or trigger an insulin response, making it irrelevant for carb counting on keto and low-carb diets.
