淨碳水化合物是身體消化成葡萄糖的碳水化合物，即碳水總量減去膳食纖維和（依常見慣例）一半的糖醇。在生酮和低碳水飲食中，人們追蹤淨碳水而非碳水總量，因為膳食纖維和大多數糖醇對血糖幾乎沒有影響。輸入營養標示上的數值，即可同時得到標準淨碳水和某些國家使用的僅扣除纖維的簡化數值。
淨碳水化合物用於估算真正會升高血糖的碳水化合物。常見的低碳水演算法是從碳水總量中減去全部膳食纖維與一半的糖醇。膳食纖維和大多數糖醇不易被吸收，因此對血糖幾乎沒有影響。
常見問題
- What are net carbs?
- Net carbs are the carbohydrates your body actually digests and absorbs as glucose. They are calculated by subtracting fiber and sugar alcohols from total carbohydrates, since those components have little effect on blood sugar.
- How do I calculate net carbs?
- Take the total carbohydrate grams from a food label and subtract grams of fiber and sugar alcohols. The result is your net carbs. This calculator does the subtraction for you so you can track the carbs that matter for low-carb diets.
- Why do net carbs matter for keto?
- Keto and low-carb plans limit the carbs that raise blood sugar, and net carbs measure exactly that. Counting net rather than total carbs lets you fit more fibrous vegetables into your day while staying under your carb limit.
