Answer key: Net Carbs worksheet

  1. 1. Net carbs: 27 g

    1. Take the sugar alcohols away from carbohydrate to get net carbs per serving. Fiber is already left out of this label's carbohydrate line

      34−7=27 g
  2. 2. Net carbs in 2 servings: 18 g

    1. Take the fiber and sugar alcohols away from total carbohydrate, since your body digests little of them. This gives net carbs per serving

      20−5−6=9 g
    2. Multiply by the number of servings you eat to get your total

      9 g×2=18 g
  3. 3. Net carbs: 23 g

    1. Take the sugar alcohols away from carbohydrate to get net carbs per serving. Fiber is already left out of this label's carbohydrate line

      28−5=23 g
  4. 4. Net carbs in 2 servings: 18 g

    1. Take the fiber and sugar alcohols away from total carbohydrate, since your body digests little of them. This gives net carbs per serving

      26−8−9=9 g
    2. Multiply by the number of servings you eat to get your total

      9 g×2=18 g
  5. 5. Net carbs: 25 g

    1. Take the sugar alcohols away from carbohydrate to get net carbs per serving. Fiber is already left out of this label's carbohydrate line

      32−7=25 g
  6. 6. Net carbs: 11 g

    1. Take the fiber and sugar alcohols away from total carbohydrate, since your body digests little of them. This gives net carbs per serving

      26−9−6=11 g
  7. 7. Net carbs: 10 g

    1. Take the fiber and sugar alcohols away from total carbohydrate, since your body digests little of them. This gives net carbs per serving

      25−7−8=10 g
  8. 8. Net carbs in 2 servings: 21 g

    1. Work out the sugar alcohols to take away: half of those other than erythritol, because the body absorbs some of them, plus all of the erythritol

      (5−0)2+0=2.5 g
    2. Take the fiber and sugar alcohols away from total carbohydrate, since your body digests little of them. This gives net carbs per serving

      22−9−2.5=10.5 g
    3. Multiply by the number of servings you eat to get your total

      10.5 g×2=21 g
  9. 9. Net carbs: 15 g

    1. Work out the sugar alcohols to take away: half of those other than erythritol, because the body absorbs some of them, plus all of the erythritol

      (8−0)2+0=4 g
    2. Take the sugar alcohols away from carbohydrate to get net carbs per serving. Fiber is already left out of this label's carbohydrate line

      19−4=15 g
  10. 10. Net carbs: 8 g

    1. Take the fiber and sugar alcohols away from total carbohydrate, since your body digests little of them. This gives net carbs per serving

      22−8−6=8 g
