7 foods to avoid with diverticulitis and dietary tips for relief

While the exact cause of diverticulitis is not fully understood, it is believed to be related to factors such as a low-fiber diet, aging, and lifestyle choices. Although medical treatment is crucial, dietary choices also play a vital role in managing diverticulitis and preventing flare-ups. Some foods can irritate the inflamed diverticula and worsen symptoms. In this comprehensive blog post, we will explore 7 foods to avoid with diverticulitis and dietary tips for relief.


7 foods to avoid with diverticulitis and dietary tips for relief

Now, let’s delve into the seven foods to avoid with diverticulitis and the reasons behind their exclusion:

  1. Popcorn
  • Popcorn is a high-fiber food, which can be problematic during diverticulitis flare-ups. The hard hulls of popcorn kernels may get trapped in diverticula, leading to irritation and inflammation.
  • Dietary Tips: Opt for low-fiber alternatives like rice cakes or pretzels for snacking. If you enjoy popcorn, consider air-popped or hull-less varieties in small quantities, once your symptoms have subsided.
  1. Nuts and Seeds
  • Nuts and seeds are another high-fiber group of foods that can be challenging for individuals with diverticulitis. The small size of seeds and hard texture of nuts can increase the risk of irritation and blockage in diverticula.
  • Dietary Tips: Avoid whole nuts and seeds and opt for nut butters or finely ground nuts and seeds. Smooth nut butters, such as almond or peanut butter, can provide a protein-rich alternative.
  1. Red Meat
  • Red meat, especially fatty cuts, can be difficult to digest and may worsen inflammation in the colon. Additionally, excessive consumption of red meat is linked to an increased risk of diverticulitis.
  • Dietary Tips: Opt for lean cuts of meat and limit red meat consumption. Instead, choose poultry, fish, or plant-based protein sources like legumes and tofu.
  1. Spicy Foods
  • Spicy foods can irritate the digestive tract and trigger diverticulitis symptoms. They may also lead to increased bowel movements, potentially exacerbating inflammation.
  • Dietary Tips: Avoid spicy seasonings, hot peppers, and heavily spiced dishes. Opt for milder herbs and spices like basil, oregano, and ginger for flavour.
  1. High-Fat Dairy
  • High-fat dairy products, such as full-fat milk and cheese, can worsen diverticulitis symptoms and lead to discomfort.
  • Dietary Tips: Choose low-fat or non-fat dairy options, such as skim milk or reduced-fat cheese. Alternatively, consider dairy-free alternatives like almond milk or soy-based products.
  1. Carbonated Beverages
  • Carbonated beverages can cause gas and bloating, potentially exacerbating diverticulitis symptoms.
  • Dietary Tips: Opt for still water or herbal teas, as they are gentler on the digestive system. Avoid carbonated drinks, sugary sodas, and caffeinated beverages.
  1. Refined Sugars and Processed Foods
  • Refined sugars and processed foods can contribute to inflammation and exacerbate diverticulitis symptoms.
  • Dietary Tips: Choose whole, unprocessed foods whenever possible. Limit sugary snacks and opt for natural sweeteners like honey or maple syrup in moderation.


Dietary Tips for Diverticulitis Relief

In addition to medical treatment and lifestyle modifications, adopting a suitable diet can play a pivotal role in managing diverticulitis and promoting digestive health. Here are some dietary tips for diverticulitis relief:


  • Drink plenty of water: Staying hydrated is crucial for maintaining regular bowel movements and preventing constipation. Aim to drink at least 8-10 cups of water daily, and more if you engage in physical activity or experience increased fluid loss.
  • Gradually increase fiber intake: While a high-fiber diet is beneficial for long-term prevention of diverticulitis, it is essential to introduce fiber gradually during a flare-up. Abruptly increasing fiber intake can worsen symptoms. Begin with low-fiber foods like cooked vegetables, white rice, and low-fiber fruits, and gradually incorporate high-fiber choices like whole grains, legumes, and fruits with skin as symptoms improve.
  • Include soluble fiber: Soluble fiber, found in foods like oats, barley, apples, and citrus fruits, dissolves in water and forms a gel-like substance in the intestines. This gel softens stools and helps ease bowel movements, providing relief during diverticulitis episodes.
  • Consider probiotics: Probiotics are beneficial bacteria that support gut health. They can aid digestion, strengthen the immune system, and reduce inflammation. Incorporate probiotic-rich foods like yogurt, kefir, kimchi, and sauerkraut into your diet or consider probiotic supplements under the guidance of a healthcare professional.
  • Avoid trigger foods: Identify and avoid foods that trigger or worsen diverticulitis symptoms. Common trigger foods include spicy foods, carbonated beverages, and those high in refined sugars and saturated fats.
  • Keep a food journal: Maintaining a food journal can help you identify potential trigger foods and monitor how different foods affect your symptoms. This information can be valuable for adjusting your diet and seeking personalized dietary advice from healthcare professionals.


Overview of Diverticulitis: Causes, Risk Factors, Symptoms, and Treatment Options

Diverticulitis is a digestive condition characterized by inflammation or infection of diverticula, small pouches that form in the colon’s lining.

Causes of Diverticulitis

Diverticulitis– is primarily caused by the formation of diverticula, small pouches that protrude through weak areas in the colon wall. The exact cause of diverticula formation is not fully understood, but it is believed to be related to several factors, including:

  1. Low-fiber diet: A diet low in fiber can lead to constipation, resulting in increased pressure inside the colon. The increased pressure may contribute to the development of diverticula.
  2. Aging: Diverticulitis is more common in older adults, and age-related changes in the colon, such as weakened muscle walls, may contribute to diverticula formation.
  3. Lifestyle choices: Sedentary lifestyle, lack of exercise, and smoking have been associated with an increased risk of diverticulitis.
  4. Genetics: Family history and genetic predisposition may play a role in the development of diverticulitis.

Risk Factors for Diverticulitis

Certain factors increase the likelihood of developing diverticulitis. These risk factors include:

  1. Age: The risk of diverticulitis increases with age, with the condition being more common in individuals over the age of 40.
  2. Diet: A low-fiber diet, high in processed foods and red meat, is a significant risk factor for diverticulitis.
  3. Obesity: Being overweight or obese can increase pressure on the colon, contributing to diverticula formation.
  4. Lack of exercise: Sedentary lifestyle and lack of physical activity can lead to constipation and increase the risk of diverticulitis.
  5. Smoking: Smoking has been associated with an increased risk of diverticulitis, likely due to its effects on the colon and blood vessels.
  6. Medications: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), may increase the risk of diverticulitis.

Symptoms of Diverticulitis

The symptoms of diverticulitis can vary in severity and may include:

  1. Abdominal pain: The most common symptom is pain, usually in the lower left side of the abdomen. The pain may be constant or intermittent and can be severe.
  2. Changes in bowel habits: Diverticulitis can lead to changes in bowel movements, including constipation or diarrhoea.
  3. Nausea and vomiting: Inflammation and infection in the colon may cause nausea and vomiting.
  4. Fever and chills: If the diverticulitis is complicated by infection, fever and chills may occur.
  5. Bloating and gas: Some individuals may experience bloating and increased gas production.

Treatment Options for Diverticulitis

Treatment for diverticulitis depends on the severity of the condition. Mild diverticulitis can often be managed with conservative measures, while severe cases may require hospitalization and surgical interventions.

  1. Mild Diverticulitis Treatment:
  • Antibiotics: For mild cases, antibiotics are prescribed to control infection and inflammation.
  • Clear liquid diet: A clear liquid diet gives the colon time to rest and heal. It includes water, broth, clear juices, and gelatin.
  • Gradual diet transition: As symptoms improve, a gradual transition to a low-fiber diet and then a high-fiber diet is recommended.
  1. Severe Diverticulitis Treatment:
  • Hospitalization: Severe diverticulitis often requires hospitalization for close monitoring and intravenous antibiotics.
  • Bowel rest (NPO): Nothing by mouth (NPO) status may be required to allow the colon to rest and heal.
  • Surgical interventions: In cases of severe complications, perforation, abscesses, or bowel obstruction, surgery may be necessary. Surgical options include bowel resection or colostomy.

Lifestyle Modifications

Lifestyle modifications are crucial in managing diverticulitis and preventing flare-ups. The following lifestyle changes can be beneficial:

  1. High-fiber diet: Gradually increasing fiber intake helps prevent constipation and promotes regular bowel movements.
  2. Regular exercise: Engaging in physical activity helps maintain a healthy digestive system and reduces the risk of diverticulitis.
  3. Stress management: Chronic stress can worsen diverticulitis symptoms, so stress-reduction techniques like meditation and relaxation are important.
  4. Smoking cessation: Quitting smoking can improve overall health and reduce the risk of diverticulitis complications.
  5. Alcohol moderation: Limiting alcohol consumption can prevent irritation and inflammation of the colon.

Importance of Seeking Medical Advice

It is crucial to seek medical advice if you experience symptoms of diverticulitis or have a history of the condition. Early intervention can help prevent complications and promote effective treatment. Healthcare professionals can accurately diagnose diverticulitis, tailor treatment plans to individual needs, and provide guidance on dietary and lifestyle changes.



In conclusion, managing diverticulitis involves a combination of medical treatment and dietary choices. By avoiding trigger foods like popcorn, nuts, and seeds, and adopting a low-fiber diet during flare-ups, individuals can alleviate symptoms and promote healing. Emphasizing a balanced and nutritious diet, along with lifestyle modifications, is essential for effective diverticulitis management. However, it is crucial to consult with healthcare professionals for personalized advice, ensuring optimal care and prevention of complications. With a holistic approach, individuals can lead healthier lives and reduce the impact of diverticulitis on their overall well-being.
