List of Foods in a High Residue Diet

By Janet Renee, MS, RD

Residue refers to undigested material, or roughage left in the digestive tract from fiber-containing foods. Fiber compounds, such as cellulose, hemi cellulose, lignin and pectin, which are in the foods you eat, pass through your system undigested. These fiber components, however, play a role in digestive health since they promote movement of food through the digestive tract and provide bulk for stool. A high-residue diet goes hand in hand with eating high-fiber foods and is commonly prescribed to treat digestive issues such as constipation and diverticulitis.

Following a High-Residue Diet

It's essential that you follow your doctor's dietary advice when it comes to medically prescribed diets. If you're not used to eating a high-fiber diet, increasing your fiber intake all at once may cause digestive issues, such as bloating and gas. Increasing your fiber intake gradually can help decrease the risk of digestive discomfort. A high-residue diet follows the standard dietary fiber intake recommendation of 25 to 30 grams of fiber per day, according to the Norman Endoscopy Center.

Breakfast Cereals

When following a high-residue diet, start your day with foods high in fiber. Adding cereal to your morning routine is an easy way to increase your fiber intake. On a high-residue diet, it's typical to aim for at least 3 grams of fiber per serving, according to the Norman Endoscopy Center. Bran cereals are particularly rich in fiber, containing 5 to 8 grams per serving on average, reports the Harvard School of Public Health. Hot cereals such as oatmeal provide another option. Oatmeal contains about 2.7 grams of fiber per serving, according to Harvard. To give your oatmeal a fiber boost, you can mix in some high-fiber, ready-to-eat cereal.

Fruits and Vegetables

Fruits and vegetables contain fiber, although the content varies greatly. Eating a wide variety of fruits and vegetables helps assure you get enough fiber for a high-residue diet. Certain vegetables are particularly rich in fiber. For example, beans and other legumes provide up to 8 grams per serving on average, according to the Harvard School of Public Health. Other high-fiber vegetables include turnips, sweet potatoes, peas, brussels sprouts and asparagus. Among the fruits that are highest in fiber are raspberries, apricots, figs and dates. Leave the skin on fruits and vegetables to get the most fiber from them.

Bread Breakdown

Eating more bread and replacing refined bread with whole-grain, high-fiber bread is another way to increase the fiber in your diet. Not all breads are rich in fiber, however. Some manufacturers add artificial coloring to make the bread look more wholesome, and some wheat bread may lack fiber. Read labels to find breads that are whole-wheat and whole-grain varieties. Because some manufacturers list the fiber content on the label, compare labels to determine which breads contain the most fiber and how much fiber you're getting per serving.
