Consuming fiber not only keeps your digestive system working properly, but it can also lessen your risk of disease. Most U.S. adults, however, consume only about half as much fiber per day as they should. If you wish to increase your fiber intake, adding fresh fruits such as oranges to your diet can play a helpful role.

A 5-ounce navel orange contains about 3 grams of total dietary fiber, according to the U.S. Department of Agriculture. Eating just one orange can help you work toward the 25 to 30 grams of fiber adults should consume daily. The fiber in oranges is composed of soluble and insoluble fiber. Soluble fiber slows digestion as it attracts water in your digestive system, and insoluble fiber increases the mass of your stools while moving through your system quickly. Harvard University Health Services reports that approximately two-thirds of an orange's fiber is of the soluble variety.
