Studies have shown that naturally occurring fiber, which nutrition experts call dietary fiber, can help reduce blood cholesterol levels, prevent constipation and reduce the risk of hemorrhoids and diverticulosis, which causes pouches to form in the large intestine.

This type of fiber comes from the parts of plants that are resistant to human digestive enzymes and may help people feel full, thereby aiding in weight loss. Some studies have also linked a high dietary fiber intake to a reduced risk of colon cancer.

Dietary fiber comes in two forms -- one form dissolves in water, the other doesn't -- and both are found in fruits, vegetables, legumes, nuts and grains. But these are foods that Americans just don't eat enough of anymore, says Mian Riaz, director of the Food Protein Research and Development Center at Texas A&M University in College Station.

and do u know SWEET POTATOES ( an example / fibers):

 

Besides simple starches, sweet potatoes are rich in complex carbohydrates, dietary fiber, beta carotene (a vitamin A equivalent nutrient), vitamin C, and vitamin B6. Pink and yellow varieties are high in carotene, the precursor of vitamin A.

In 1992, the Center for Science in the Public Interest compared the nutritional value of sweet potatoes to other vegetables. Considering fibre content, complex carbohydrates, protein, vitamins A and C, iron, and calcium, the sweet potato ranked highest in nutritional value. According to these criteria, sweet potatoes earned 184 points, 100 points over the next on the list, the common potato.(NCSPC)

Sweet potato varieties with dark orange flesh have more beta carotene than those with light coloured flesh, and their increased cultivation is being encouraged in Africa, where vitamin A deficiency is a serious health problem. Despite the name "sweet", it may be a beneficial food for diabetics, as preliminary studies on animals have revealed that it helps to stabilize blood sugar levels and to lower insulin resistance.[13] Some Americans, ( me too !) are advocating increased consumption of sweet potatoes both for their health benefits and because of their importance in traditional Southern cuisine.
