Fiber is carbs, but unlike most of the carbs in the human diet, people cannot convert them into simple sugars.

The point is how much of the carbs are you actually getting. The fibers that you excrete isn't part of your net intake.

By definition, the human body cannot convert fiber into carbs the human body can burn (but microbes do turn some of the fiber into short-chain fatty acids, which is fuel for human colon cells). That is how "fiber" is defined.

Yes that is my understanding too. Short chained saturated fat to be exact, so don't tell any of the lipophobics or they will automatically add the prefix "unhealthy" to it as they are accustomed to.

In this thread, I was so eager to make sure you didn't have some wrong belief somehow that I didn't even notice you were agreeing with me (or concisely summarizing). I have a bad habit of focusing too much on any errors the other person might have made.

(Maybe we should think of a word that means "carb that the human body can efficiently convert into glucose or fructose" and try to spread that new word. "Insulinogen"?)
