Grab something with a nutrition label and look at the “carbs” section. You’ll see total carbs, dietary fiber, sugars and (if present) sugar alcohols.
Confusingly, “total carbs” is sometimes more than the sum of the sub-categories. That’s because starch, another type of carb, is not shown. And sometimes, food packaging also calls out “net carbs” (that’s total carbs minus dietary fiber).
If you’re a human, you have one or more good reasons to pay attention to these different types of carbs.
