What is the difference between "fiber" and "dietary fiber" and "carbs" and "net carbs"?

Several!: It is good self-nutritional support to know these points! first, carbs are all carbohydrates, including sugar and fiber. Usually, the non-sugar carbs, after subtracting fiber, are starch. Net carbs are total carbs, minus fiber, both soluble and insoluble. Some foods may contain sugar alcohols, which have little impact on Insulin secretion, and therefore, do not act like carbs.
