What is
Fiber?
Fiber is a virtually
indigestible substance that is found mainly in the outer
layers of plants. Fiber is a special type of carbohydrate
that passes through the human digestive system virtually
unchanged, without being broken down into nutrients.
Carbohydrates constitute the main source of energy for all
body functions.
Benefits
Fiber plays an important role
in keeping the digestive system running smoothly by
promoting regularity. Fiber adds bulk to help move food
through the digestive tract.
Fiber may also be important for
people who have diabetes. Diets high in whole grain and
fiber have been shown to help people with diabetes manage
their blood sugar and cholesterol levels.
Getting enough fiber can also help curb your hunger and help
you feel satisfied, which can help with weight management.
Research suggests that people who have higher intakes of
fiber tend to have healthier body weights.
Where Are They Found?
Good sources of fiber are: Whole grains (bran has the
highest fiber content); this includes breads and cereals,
whole-grain pastas, and brown rice, nuts and seeds, legumes, fruits,
and vegetables. |
