Purpose
Dietary fiber is the part of a plant that provides and maintains the
plant's structure. Cellulose, hemicellulose, polysaccharides, pectins,
gums, mucilages, and lignins are dietary fibers. These fibers are unrelated
chemically, however, they all have one thing in common -- they can't be
digested by the human body. For this reason, they can help correct disorders
of the large intestine (colon), and keep it functioning normally. Therefore,
it is important to increase the amount of fiber in the diet.
Function of The Colon
The main job of the colon is to complete the digestion process. This occurs
by removing excess water from food wastes entering from the small intestine.
When wastes pass through the intestines too quickly, not enough water
is absorbed. Watery stools and diarrhea are the result. In contrast, if
the passage of waste is too slow, too much water is absorbed. This results
in hard stools and constipation, which often leads to straining. These
simple problems occasionally lead to more serious disorders.
The Importance of Dietary Fiber
Fiber (also called roughage or bulk) promotes the wavelike contractions
that keep food moving through the intestine. Also, high-fiber foods expand
the inside walls of the colon. This eases the passage of waste. Fibrous
substances pass through the intestine undigested. They also absorb many
times their weight in water, resulting in softer, bulkier stools.
Studies show that rural Africans, who eat diets high in fiber, eliminate
food waste in one-third the time it takes people from urban westernized
cultures. Their stools are larger and softer. Because of the greater bulk
and speed of foods through the digestive tract, it is believed that harmful
substances are also swept out before they can cause problems. In fact,
these rural people have fewer of the digestive tract diseases that plague
Western man. It is thought that this may be related to the nature of their
diet.
A high-fiber diet causes a large, soft, bulky stool that passes through
the bowel easily and quickly. Because of this action, some digestive tract
disorders may be avoided, halted, or even reversed simply by following
a high-fiber diet. A softer, larger stool helps prevent constipation and
straining. This can help avoid or relieve hemorrhoids. More bulk means
less pressure in the colon, which is important in the treatment of irritable
bowel syndrome and diverticulosis (defects in the weakened walls of the
colon). In addition, fiber appears to be important in treating diabetes,
elevated cholesterol, colon polyps, and cancer of the colon.
Nutrition Facts
As long as a balanced selection of foods from each of the basic food groups
is chosen, the High Fiber Diet is nutritionally adequate. Some studies
indicate that excessive intake of certain dietary fiber sources may bind
and interfere with the absorption of the following minerals: calcium,
copper, iron, magnesium, selenium, and zinc. However, there appears to
be no problem for those adults who follow a balanced, regular diet. Occasionally,
a physician may prescribe supplements.
The Use of Fiber in the Irritable Bowel
Irritable bowel syndrome (IBS) is one of the most common disorders of
the lower digestive tract. There is no disease present with IBS, but it
creates bothersome symptoms such as altered bowel habits -- constipation,
diarrhea, or both alternately. There may also be bloating, abdominal pain,
cramping, and spasm. An attack of IBS can be triggered by emotional tension
and anxiety, poor dietary habits, and certain medications. Increased amounts
of fiber in the diet can help relieve the symptoms of irritable bowel
syndrome by producing soft, bulky stools. This helps to normalize the
time it takes for the stool to pass through the colon. Liquids help to
soften the stool. Irritable bowel syndrome, if left untreated, may lead
to diverticulosis of the colon.
Fiber and Colon Polyps/Cancer
Colon cancer is a major health problem. This disease is most common in
Western cultures. Most colon cancer starts out as a colon polyp, a benign
mushroom-shaped growth. In time it grows, and in some people it becomes
cancerous. Colon cancer is usually always curable, if polyps are removed
when found or if surgery is performed at an early stage. It is now known
that people can inherit the risk of developing colon cancer, but diet
may be important, too. There is a very low rate of colon cancer in residents
of countries where grains are unprocessed and retain their fiber. The
theory is that in the Western world, cancer-containing agents (carcinogens)
remain in contact with the colon wall for a longer time and in higher
concentrations. So, a large bulky stool may act to dilute these carcinogens
by moving them through the bowel more quickly. Less carcinogenic exposure
to the colon may mean fewer colon polyps and less cancer.
Fiber and Diverticulosis
Prolonged, vigorous contraction of the colon, usually in the left lower
side, may result in diverticulosis. This increases pressure causing small
and eventually larger ballooning pockets to form. These pockets usually
cause no problems. However, sometimes they can become infected (diverticulitis)
or even break open (perforate) causing pockets of infection or inflammation
of the sac lining the abdomen (peritonitis). A high-fiber diet may increase
the bulk in the stool and thereby reduce the pressure within the colon.
By so doing, the formation of pockets is reduced or possibly even stopped.
Some professionals recommend restricting the following foods in diverticulosis
diets: nuts, poppy seeds, caraway seeds, rye seeds, popcorn, crunchy peanut
butter, corn, cucumber, and squash; as well as fruits and vegetables with
seeds such as strawberries, figs, and tomatoes. However, there has never
been any medical proof that these foods are injurious. Many gastroenterologists
allow and even encourage consuming these foods, depending on an individual's
tolerance.
Fiber, Cholesterol and Gas
Insoluble fiber is found in wheat, rye, bran, and other grains.
It is also the fiber found in most vegetables. Insoluble fiber means
it does not dissolve in water. It also cannot be used by intestinal-colon
bacteria as a food source, so these beneficial bacteria generally do not
grow and produce intestinal gas.
Soluble fiber, on the other hand, does dissolve in water forming a gelatinous
substance in the bowel. Soluble fiber is found in oatmeal, oat bran, fruit,
psyllium (Metamucil, Konsyl), barley, and legumes. Soluble fiber, among
its other benefits, seems to bind up cholesterol allowing it to be eliminated
with the stool. If enough is removed it can lower the blood cholesterol
10-15%.
The down side of soluble fiber is that it can be metabolized by gas forming
bacteria in the colon. These bacteria are harmless but for those who have
an intestinal gas or flatus problem it is probably best to avoid or carefully
test soluble fibers to see if they are contributing to intestinal gas.
Whenever possible, both soluble and insoluble fiber should be eaten on
a daily basis.
A Dietary Fiber Supplement May Be Helpful
Some people don't tolerate fibrous foods well. If you can't consume enough
fiber in your diet alone, certain stool softening and bulking agents are
available. These products absorb water and produce the bulk necessary
for the digestive tract to perform naturally. They help create a soft
and well-formed stool. For this reason, they can be very useful in preventing
and treating digestive tract disorders. Metamucil, Konsyl, and Per Diem
Fiber are such products. These contain psyllium mucilloid and come from
the seed of the psyllium plant. Citrucel (hemicellulose) and FiberCon
(polycarboxisal) are other bulking agents that can also be used.

Special Considerations
|
|
To improve your diet, add foods that contain more dietary fiber.
You can include some or all of the following:
- Whole-grain foods (such as bran cereals) and breads (those
made with whole wheat grains).
- Fresh fruits (including the skin and pulp).
- Dried or stewed fruits (such as prunes, raisins, or apricots).
- Root vegetables (such as carrots, turnips, or potatoes).
- Raw or fresh vegetables, such as cabbage. (Lettuce is actually
low in fiber.)
Eating bran cereal in the morning is often the easiest way to
obtain fiber. All-Bran, 100% Bran, Bran Buds, oat bran, oatmeal,
and Raisin Bran are some of the high-fiber cereals presently available.
Bran can cause rumbling intestinal gas and even some mild cramping,
so it should be eaten in small amounts at first. The amount can
be increased as the body gets used to it. The goal should be one
to two large, soft, formed stools a day.
You should also try to follow these dietary rules:
- Drink plenty of liquids, including fruit or vegetable juices
and water. Drink at least six cups of water or fluid a day.
- Eat slowly. Chew your food thoroughly. This allows the saliva
and digestive juices of the stomach, liver, and pancreas to
break down food more easily. It may also help prevent problems
from developing in the lower digestive tract.
- Eat your meals at regular intervals.

Fiber Contents of Foods
Goal (25 to 35 grams per day)
Common servings of foods containing dietary fiber are shown below. Increase
your intake by including fiber from all sources. (Foods from meat and
dairy groups are not good sources.) Foods that are good sources of fiber
are also typically low in fat.
