Fiber is found in plants and is not broken down by the body.
There are 2 forms of fiber, soluble and insoluble.
Insoluble fiber provides what is called bulk. It is used by the large intestine to help remove waste in bowel movements.
Soluble fiber can slow glucose (sugar) absorption and help lower your cholesterol levels. Both types of fiber are an important part of your diet.
Usually both types of fiber are contained in foods. Many food labels do not tell you the amounts of each type of fiber contained in the food. What is most important is that you get 20 to 35 grams of fiber a day.
Lack of fiber in your diet can worsen intestinal problems, such as constipation, and can lead to more serious problems in the future.
Sources of insoluble fiber are whole grains such as wheat and rye, flax seeds, nuts, brown rice, and vegetables.
Sources of soluble fiber are citrus fruits, apples, oatmeal and oat bran, and beans.
