Interesting, indeed. This link starts by pointing out that despite fiber's integral dietary role, it's not considered a "nutrient". This distinction, along with fiber possibly not having the most wonderful reputation,(I doubt I'm alone in my mind going straight to prunes, prune juice, and metamucil) are probably at least some of the reason that Americans, on average get only 17 grams of fiber daily, when 25-38 grams are recommended. Check out the link, it's brief, but full of facts about the benefits of upping your fiber intake. It also has tips for easy ways to increase your fiber! Be healthy, my friends.
