All dietary fiber is beneficial for your health--they aid your digestive and cardiovascular health, as well as helping to prevent illnesses such as cancer, diabetes, diverticulitis, obesity and constipation. Insoluble fiber provides a laxative effect on your digestive organs--that is, it adds bulk to your diet and helps you to avoid constipation. This type of fiber does not dissolve in water. Instead, they pass through your stomach, intestines and colon relatively unchanged, helping to speed the passage of wastes through your system.
Good sources of insoluble fiber include whole wheat and grains, wheat, corn and oat brans, barley, nuts, couscous, bulgur, brown rice, cabbage, zucchini, celery, onions, cucumbers, carrots, tomatoes, green beans, raisins, grapes, green, leafy vegetables, fruits and root vegetable skins. Learn more about insoluble fiber by reading our Bright Hub guides.
