We're glad you asked! It's actually not as difficult as you may think. Carbs are in just about everything we eat, and they are one of the 3 primary macro-nutrients, in addition to fat & protein. But not all carbs are created equal - there are "good carbs" and "bad carbs."
Bad carbs come primarily from refined sugars and have little nutritional value, whereas good carbs are minimally processed and contain the fiber found naturally in the food.
Fiber is considered a "good carb." Certain natural sugars such as allulose are also considered "good carbs" because they are not metabolized by the body. These "good carbs" can be subtracted from total carb count to give you net carbs.
Let's look at an example: our Sour Gummy Worms contain 37g total carbohydrates, but it also contains 18g fiber and 13g allulose. These are indeed carbs, but they can be subtracted from the total to calculate net carbs: 37 - 18 - 13 = 6g net carbs.
