Overview of Diverticulitis

Diverticulitis is a digestive disorder that affects the large intestine and can be caused by a variety of factors. Symptoms of this disorder can range from mild abdominal pain and constipation to severe cramping and diarrhea.

A proper diet can help alleviate or even prevent symptoms of diverticulitis and it’s important to understand the specifics in order to get the most benefit from an appropriate diet.

Definition of Diverticulitis

Diverticulitis is a condition that arises when the small, bulging pouches in the digestive tract (known as diverticula) become inflamed or infected. It is estimated that about 10 percent of people over the age of 40 have diverticulitis. The exact cause of this condition is not known, but it is believed to be related to low-fiber diets and aging.

When someone suffers from diverticulitis, they will often experience abdominal pain, bloating, and diarrhea or constipation. Other common symptoms include nausea and vomiting, loss of appetite, fever and chills.

Treatment typically involves:

  • Dietary changes including increasing intake of high-fiber foods such as whole grains, fruits and vegetables as well as reducing consumption of processed foods and saturated fats.
  • In addition to dietary changes, antibiotics may also be prescribed depending upon the severity of the infection.

Symptoms of Diverticulitis

Symptoms of diverticulitis vary, but can include abdominal pain or cramping, nausea and vomiting, fever, bloating, constipation or diarrhea, constipation and diarrhea alternately, and rectal bleeding. The location of the pain may vary from person to person. Diverticulitis can be a serious condition and require medical treatment. If left untreated it can lead to infection or a perforated colon which is an emergency situation. Some people may not experience any symptoms at all as diverticulitis is often symptomless in its early stages. It’s therefore important that those diagnosed with diverticulosis are aware of potential signs and symptoms so they can seek help if these symptoms occur.

In addition to medical treatment it is important to follow a healthy diet which includes avoiding foods that can cause irritation to the lining of the intestine such as popcorn kernels, seeds and nuts which are difficult for the body to break down. Foods high in fiber such as whole grains, legumes, fruits and vegetables should be included in your diet as they will help keep your digestive system healthy.

Causes of Diverticulitis

Diverticulitis occurs when the small, bulging pouches in the digestive tract become infected and inflamed. Diverticulitis can be caused by a variety of factors, including:

  • A lack of fiber in the diet
  • A sedentary lifestyle
  • Being overweight or obese

Other risk factors include advancing age, smoking, and certain medications. Understanding the underlying causes of diverticulitis can help sufferers make informed decisions about their diet and lifestyle choices.

Poor Diet

The most common cause of diverticulitis is a poor diet low in fiber. Eating a diet that is low in fiber can put stress on the digestive system, leading to pockets (diverticula) forming in the intestines and becoming infected, resulting in diverticulitis. When a high-fiber diet is not being consumed, waste matter can become lodged inside the pockets, causing inflammation and infection.

Common sources of fiber include:

  • Legumes
  • Seeds and nuts
  • Whole grains
  • Fruits
  • Vegetables

Additionally, maintaining adequate hydration can help reduce the risk of developing diverticulitis. Drinking plenty of liquids along with foods high in fiber helps soften stools so they are more easily eliminated from the body. This helps reduce pressure on the colon walls and prevents blockages that could trigger an attack of diverticulitis.

Lack of Fiber

Lack of fiber in the diet can be a major cause of diverticulitis. Diverticulitis occurs when the small pouches (diverticula) located in the lower part of the large intestine become inflamed and infected.

The best way to prevent this is to keep your digestive tract healthy by consuming enough dietary fiber. Eating a diet that is high in fiber helps promote good digestive health, as well as reduce the risk of developing complications from diverticulitis such as inflammation or infection.

Good sources of dietary fiber include:

  • Whole grains
  • Beans and legumes
  • Fruits and vegetables
  • Nuts and seeds
  • Wheat bran cereals

Eating a variety of these foods can help ensure you get an adequate amount of dietary fiber for optimal digestive health and reduced risk for diverticulitis.

Diet Recommendations

If you suffer from diverticulitis, it is important to maintain a healthy diet to help manage and reduce your symptoms. A diet plan for diverticulitis should include:

  • Whole grains
  • High fiber fruits and vegetables
  • Lean protein sources

It should also avoid processed foods, excess fat and sugar, and alcohol. Let’s dive into the specifics of what a diverticulitis diet should look like.

Foods to Avoid

When suffering from diverticulitis, it is best to avoid certain foods that may trigger a flare-up. All fried, processed and high-fat foods, including red meat and all processed meats (chicken nuggets, deli meat), should be avoided. Highly acidic fruits such as oranges, grapefruits and lemons can cause irritation to the intestines. Additionally, any food products containing high levels of sugar or artificial sweeteners should be avoided.

Other dietary considerations for those with diverticulitis are avoiding spicy foods, nuts and seeds (including nut butters), popcorn and popcorn kernels, raw vegetables (other than leafy greens). It is recommended to limit breads that contain seeds and nuts. If you must eat breads containing those items it is best to remove the seeds before consuming them. Additionally, caffeine should also be avoided when possible as it can often make symptoms worse.

Foods to Include

When it comes to diet recommendations for diverticulitis sufferers, there are certain foods that need to be included in their meal plans. These include high-fiber foods such as legumes, beans, whole grains, fruits and vegetables. All of these should be taken in their raw or lightly cooked form. Additionally, adding probiotic-rich foods such as yogurt and kefir can be beneficial for digestion.

Lean proteins such as lean meats, poultry and fish are also recommended to provide the body with nutrients it needs without increasing the risk of irritation in the digestive system. Additionally, foods like olive oil and omega-3 fatty acid-rich foods can be beneficial for overall health when enjoyed in moderation.


Nutritional supplements can also be beneficial for those suffering from diverticulitis. The primary supplements to consider are probiotics, which are beneficial bacteria that help to protect the digestive tract and improve gut health.

Other supplements to consider include omega-3 fatty acids, vitamin D, and glutamine, which can all help reduce inflammation, support the immune system, and help with the healing process.


Probiotics are a type of beneficial bacteria that live in your digestive tract, providing many health benefits. People with diverticulitis are often encouraged to add probiotics to their diet as it has been shown to help manage symptoms and reduce inflammation.

Probiotics can be found in many food sources such as dairy products, such as yogurt and kefir, and cultured vegetables like kimchi, miso soup, sauerkraut etc., and supplements.

When choosing a supplement, it is important to select one that contains at least 10 different strains of beneficial bacteria. It is also important to choose one with a high strain count (at least 5 billion CFU per serving).

In addition to improving digestive health for those with diverticulitis, probiotics can also help improve general health by boosting immunity and reducing inflammation.

Fiber Supplements

Fiber supplements are a great way to get additional fiber into your diet if you suffer from diverticulitis. Fiber helps to keep your digestive system clean and healthy, and fiber supplements provide an easy way of getting the recommended amount of fiber each day.

Some of the most common types of fiber supplements are:

  • Psyllium husk powder, made from the outer coating of psyllium seeds and can be used as either a supplement or an ingredient in baking recipes.
  • Oat bran, a type of dietary fiber made from hulled oats that have been ground into a fine powder and can be added to yogurt or smoothies for a boost in nutrition.
  • Ground flaxseeds, high in both soluble and insoluble fibers, so it helps slow digestion by keeping food in the stomach for longer periods of time.
  • Guar gum, made from the endosperm of guar beans and can be used as a thickening agent when added to soups or other liquids.
  • Inulin, derived from chicory root and works to increase beneficial bacteria levels within the gut while also aiding digestion by helping decrease sugar absorption.

Lifestyle Changes

Making the right lifestyle changes can be essential in keeping diverticulitis symptoms under control. Eating a healthy and balanced diet, getting enough exercise, and eliminating stress can all have a major impact on the condition.

Let’s look at what lifestyle changes are recommended for diverticulitis sufferers:


Regular physical activity is vital for people with diverticulitis. Exercise helps reduce inflammation, improves digestive health, and decreases pain symptoms. It also helps reduce cholesterol levels and the risk of developing other chronic diseases.

Regular physical activity can help manage the disease in two ways: by reducing your risk factors for developing diverticulitis or helping you cope better with existing symptoms.

When it comes to exercise, it is important to focus on activities that improve cardiovascular fitness and overall strength and endurance. Examples of aerobic activities include walking, jogging, swimming, cycling, and dancing. Resistance training can also be beneficial by strengthening the core muscles of your abdomen to support good digestion and healthy bowel movements. Additionally, stretching exercises like yoga can be useful for relieving stress from your digestive system as well as helping you relax and improve flexibility.

Stress Management

Stress management is an important aspect when it comes to dietary and lifestyle changes for Diverticulitis sufferers. In order to manage stress, it is important to get enough rest, relaxation and exercise. Regular physical activity such as walking, cycling or even swimming can help reduce stress levels. Additionally, getting involved in activities that you enjoy can be a great way of reducing stress. Stress management techniques such as meditation or mindfulness can also be helpful for controlling irritability and mood swings caused by diverticulitis symptoms.

It is also beneficial to increase self-care; avoiding alcohol and smoking can further help suppress stress associated with the condition. Lastly, eating smaller meals more frequently rather than larger meals less often may help alleviate symptoms of altered bowel habits associated with Diverticulitis.


In conclusion, people with diverticulitis should follow a well-rounded diet that includes plenty of fiber-rich foods such as fruits, vegetables, and whole grains. Additionally, they should limit their intake of fat, including dairy and red meat. Furthermore, those with diverticulitis should drink plenty of water to stay hydrated and help prevent constipation. Finally, people with diverticulitis should consider speaking to a nutrition professional to ensure they are following a safe and healthy dietary plan that fits their individual needs.

Following a well-rounded diet is important for everyone’s health but it is especially important for those with diverticulitis in order to reduce the chances of exacerbating symptoms or suffering from further complications.
