Diverticulosis Diet

Medically reviewed by Last updated on Feb 6, 2023.

What is a diverticulosis diet?

A diverticulosis diet includes high-fiber foods. High-fiber foods help you have regular bowel movements. Extra fiber may decrease your risk of forming new diverticula (small pockets) in your intestine. A high-fiber diet may also help prevent diverticulitis. Diverticulitis is a painful condition that occurs when diverticula become inflamed or infected. You do not need to avoid nuts, seeds, corn, or popcorn while you are on a diverticulosis diet.


How much fiber do I need?

You may need 25 to 35 grams of fiber each day. Ask your dietitian or healthcare provider how much fiber you should have. Increase your intake of fiber slowly. When you eat more fiber, you may have gas and feel bloated. You may need to take a fiber supplement if you do not get enough fiber from food. Drink plenty of liquids as you increase the fiber in your diet. Your dietitian or healthcare provider may recommend 8 eight-ounce cups or more each day. Ask which liquids are best for you.
