Dietary Changes for Managing Diverticulitis or Diverticulosis

Certain foods can help prevent complications of diverticulitis or diverticulosis, two issues that affect the colon. Diverticulosis happens when small pouches form in the walls of the colon. Diverticulitis then happens when a tear develops in one of those pouches. These can lead to inflammation or infection in the pouches which causes abdominal pain. 

Dietary Recommendations 

For managing diverticulosis and preventing or managing diverticulitis, a high-fiber diet is generally recommended, along with adequate hydration and regular exercise. 

1. High-Fiber Diet (for Diverticulosis and Prevention):

  • Why it's important:
    Fiber helps soften stools, making them easier to pass and reducing pressure in the colon, which can help prevent diverticulitis flare-ups. 

  • Foods to include:

    • Fruits: Apples, pears, bananas, berries, oranges, kiwis. 

    • Vegetables: Broccoli, carrots, spinach, kale, collard greens, cauliflower, and other leafy greens. 

    • Whole Grains: Oatmeal, brown rice, quinoa, barley, whole wheat bread and pasta. 

    • Legumes: Beans, lentils, chickpeas. 

    • Nuts and Seeds: Almonds, pistachios, chia seeds, flax seeds. 

  • Tips:

    • Increase fiber gradually: To avoid gas and bloating, start by adding fiber-rich foods slowly and increase your intake gradually. 

    • Drink plenty of water: Fiber absorbs water, so staying hydrated is crucial. 

    • Be active: Regular exercise helps with bowel movements and can prevent constipation. 

2. Managing Diverticulitis Flare-Ups:

  • Temporary Dietary Changes:

    • Clear Liquid Diet: During a flare-up, your doctor might recommend a clear liquid diet to rest your digestive system. 

    • Low-Fiber Diet: After the initial phase, a low-fiber diet may be recommended until symptoms subside. 

  • Foods to Include (during flare-ups):

    • Clear broths, water, fruit juices without pulp, gelatin, tea, and popsicles. 

    • White rice, white bread, and pasta. 

    • Tender meats (fish, chicken) and eggs. 

  • Foods to Avoid (during flare-ups):

    • High-fiber foods (fruits, vegetables, whole grains, nuts, seeds). 

    • Foods that are hard to digest (onions, nuts, seeds, fruit and vegetable skins). 

  • Important:
    Follow your doctor's recommendations for dietary changes during a flare-up and gradually reintroduce fiber as symptoms improve. 

3. Foods to Limit or Avoid (in General):

  • Red Meat: Some studies suggest that a high intake of red meat may increase the risk of diverticulitis. 

  • Processed Foods: Limit processed foods and foods high in saturated fat. 

  • Foods that Irritate the Bowel: Some individuals may find that certain foods trigger or worsen their symptoms. Pay attention to how your body reacts to different foods and adjust your diet accordingly. 

4. Other Important Factors:

  • Hydration: Drink plenty of fluids, especially water, to help keep stools soft and prevent constipation. 

  • Regular Exercise: Engage in regular physical activity to promote healthy bowel movements. 

  • Consult with a Healthcare Professional: If you have diverticulosis or diverticulitis, consult with your doctor or a registered dietitian to develop a personalized dietary plan that meets your specific needs.
