The
Importance of Fiber to a Healthy Diet
When
it comes to eating healthy and enjoying a healthier lifestyle, it is
hard to overstate the importance of fiber in the diet. Even though
fiber is most associated with grains, rice and breads, it is
important to remember that fruits and vegetables also contain
significant amounts of dietary fiber. In fact, the need for fiber is
just one more reason to eat your fruits and vegetables every day.
In
order to understand why dietary fiber is so important, it is a good
idea to know what fiber is and what role it plays in digestion.
Simply put, dietary fiber is the portion of food that the human body
cannot digest. Fiber is found in foods of plant origin only; there
is no fiber in meat and dairy products. Fiber plays an important
role in the digestion of food, and in the elimination of waste
products as they travel through the body.
Good
sources of dietary fiber include grains, cereals, legumes, lentils,
nuts, seeds, fruits and vegetables. As we said before, meats and
dairy products do not contain any dietary fiber, so it is important
to eat some plant based foods ever day to get the fiber you need.
Soluble
vs. insoluble
Not
all fiber is the same, and fiber comes in two forms – soluble and
insoluble. All plant materials contain both types of fiber, but some
sources contain more of one than the other. Eating a variety of
foods rich in fiber every day will ensure you get adequate levels of
both soluble and insoluble fiber.
Insoluble
fiber is important in keeping people regular, and it has shown
promise as well in the prevention of some types of colon and rectal
cancers. Insoluble fiber is mainly found in wheat brain, some types
of vegetables and in whole grain products. Some vegetables rich in
insoluble fiber include carrots, peas and broccoli. The skins of
fruits are also rich in insoluble fiber.
Soluble
fiber, on the other hand, has shown promise in reducing levels of
cholesterol in the blood, and at reducing the rate at which glucose
enters the bloodstream. Soluble fiber is abundant in dried peas,
lentils, beans, barley, oat bran, and in many fruits and vegetables.
How
much fiber is enough
Many
people are unsure just how much dietary fiber they need every day,
but most dietitians recommend that women consume between 21 and 25
grams of dietary fiber per day. For men, the recommendation is 30 to
38 grams of fiber each day.
Of
course, that is easier said that done, and it is important to know
which foods are high in fiber in order to boost your daily fiber
consumption. In the case of packaged foods like breads and crackers,
the fiber content will be listed as part of the nutritional label. In
the case of fruits and vegetables, there are charts which show the
fiber content of an average size piece. Some grocery stores post
this information, and it is also widely available on the internet.
When
increasing dietary fiber, it is best to make the increase gradual. A
sudden jump in dietary fiber can lead to bloating, gas and abdominal
discomfort. In addition, it is important to drink plenty of fluids,
especially water, in order for fiber to have the best effect. When
choosing breads and cereals, it is best to go with healthier whole
grains. In general, the less processing, the healthier the foods.
Eating
the skins of fruits and vegetables is a great way to increase dietary
fiber. Many people like to make fruit shakes and smoothies that use
the skins of their favorite fruits. This makes a delicious and
nutritious way to increase fiber consumption. In addition, keeping
a variety of fiber rich foods, such as apples, nuts, seeds and bran
muffins, around for snacks is a great idea.
And
finally, eating a wide variety of foods will ensure that you get
plenty of fiber, as well as the vitamins, minerals, and trace
elements that make a balanced diet so important.
