For today’s post, I thought I would make it short and
present a bit of information on dietary fiber. Media and marketers have been beating
the drum on this component of nutrition, but when I ask some of my clients what
they know about fiber, the response I most frequently receive is a blank stare.
Lucky
for us, it’s not too complicated. So, here we go…
First:
fiber has two forms - soluble and insoluble.
Soluble fiber is
absorbed in the large intestine where it slows the movement of food and allows organ plenty
of time for the absorption of nutrients. As a result, fiber can also help in
avoiding drastic swings in
blood sugar. Its primary sources are fruits, vegetables,
legumes and oat bran.
Insoluble fiber (aka.,
“roughage”) is what most people think of when they think or fiber. In any case,
insoluble fiber absorbs water during digestion, creating
a “fuller” feeling and thereby increasing fecal bulk and
speeding its movement
through the digestive tract. Sounds a bit vulgar, but there’s a good side: It
helps prevent constipation
and is believed to prevent colon cancer.
It is also this feeling of satiety or
fullness that allows fiber to help curb appetite. Although the average American eats 10 to 20 grams of fiber a day, the
recommended level is relatively higher; 25 to 35 grams a day.
But before you decide to go out and aggressively pile on the
dietary fiber to compensate for your previous short-comings, I suggest you
increase you intake of fiber gradually in
order to avoid possible intestinal discomfort and embarrassment.
That said – Enjoy Your Life!
