INCREASING FIBER IN YOUR DIET
If your
goal is to lose body fat, increasing your fiber intake can help
in many ways. Firstly, high fiber foods has been known to lower
your appetite by lowering the insulin levels in your
bloodstream. Insulin is a hormone that stimulates appetite.
Secondly, the body uses more energy (and burns more calories) to
process and absorb high-fiber foods. That is one reason why
fiber plays such a big role in the so-called “negative calorie”
diets. Thirdly, high fiber foods are filling but are low in fat.
Some are even fat free! That way you feel satisfied but still
keep well within your prescribed calorie intake.
Today’s
typical diets don’t have much fiber, since much of the natural fiber
content in fruits and vegetables are destroyed in the food refining
process. Most adults consume less than 20 grams of fiber per day.
This is approximately 50% of the recommended amount of dietary fiber
for good health, so it is certainly one aspect of healthy eating
that needs some attention.

What is fiber? Dietary
fiber is found only in plant foods that contain cellulose or
cellulose derivatives. They can’t be broken down by the body because
we don’t have the proper digestive enzymes. There are two types of
fiber, water-soluble and water-insoluble, with unique and separate
benefits associated with each.
·
Water soluble Fiber.
This can be found in
fruits, vegetables, oat bran, seeds, soybeans, peas. It plays an
important role in regulating blood lipid levels (cholesterol and
blood fats or triglycerides) by binding with bile acids and
preventing cholesterol and fat from being reabsorbed by the body. It
has also been linked to improved glucose tolerance.
·
Water
insoluble fiber. This can be found in whole wheat,
wheat bran and other grains, fruit and vegetable skins. It helps to
prevent constipation, and is associated with preventing
diverticulitis, irritable bowel syndrome. Some studies have also
shown that it reduces risk for colon cancer.
·
Fiber and
digestion. Fiber
stimulates digestion, which is very important when the diet is
otherwise high in animal foods, which contain no fiber and may
contain potentially cancerous substances. Fiber helps “clean” the
body of these substances, and reduces your exposure to these
dangerous toxins.
·
Good sources of
Fiber. Fiber can only be
found in plant foods that haven't had the fiber removed or destroyed
during processing. Some good sources include whole wheat breads and
whole grain cereals like brown rice, amaranth, oats, barley; fruits
and vegetables of all types (especially those with edible skins),
seeds, berries, dried fruits, and beans of all types.
Pace
yourself!
Slowly introduce
fiber into your system. Increasing the amount too quickly can cause
uncomfortable bloating and gas, an unfortunate side effect of the
indigestible substances in fiber. The best way to strike a balance
is to add high fiber foods in small amounts over a long period of
time, building up a tolerance to these foods. Drink plenty of water
to help digestion.
