It's also OK to eat small fruits with seeds, such as strawberries and blueberries. Research has found that these foods are not associated with an increased diverticulitis risk.
Actually, no specific foods are known to trigger diverticulitis attacks. And no special diet has been proved to prevent attacks. In the past, people with small pouches (diverticula) in the lining of the colon were told to avoid nuts, seeds and popcorn.
Historically, it was recommended that a 'low residue' diet should be followed. This meant avoiding poorly digested foods such as nuts, seeds, popcorn and fruit and vegetable skins, as it was thought that these foods might get stuck in the diverticular pouches and cause them to become inflamed or infected.
A diagnosis of diverticulitis no longer means you have a long list of foods to avoid. At one time, doctors recommended avoiding nuts, popcorn, seeds and even fruits or vegetables with seeds (like tomatoes or strawberries). But recent studies suggest those foods do not contribute to flare-ups and are fine to eat.
Good options include canned fruits such as peaches or pears, applesauce, ripe bananas, and soft, ripe cantaloupe and honeydew. “It's not a lot of fiber because you're not eating the skin. The skins are the source of insoluble fiber, which can irritate inflamed polyps.”
There are no specific foods you need to avoid. You do not need to avoid any foods such as nuts, seeds, corn, popcorn or tomatoes if you have diverticular disease. These foods do not make diverticular disease worse. These foods may even help prevent it because they are high fibre choices.
In the past, doctors had recommended that people with diverticular disease (diverticulosis or diverticulitis) avoid hard-to-digest foods such as nuts, corn, popcorn, and seeds, for fear that these foods would get stuck in the diverticula and lead to inflammation.
Mild cases of diverticulitis are usually treated with antibiotics and a low-fiber diet, or treatment may start with a period of rest where you eat nothing by mouth, then start with clear liquids and then move to a low-fiber diet until your condition improves. More-severe cases typically require hospitalization.
The most common symptom of diverticular disease is intermittent (stop-start) pain in your lower abdomen (stomach), usually in the lower left-hand side. The pain is often worse when you are eating, or shortly afterwards. Passing stools and breaking wind (flatulence) may help relieve the pain.
Plus, probiotics have anti-inflammatory effects, which may help to ease inflammation from diverticulitis. Probiotics are available in supplement form, but they can also be found in certain foods, such as yogurt, kombucha, and fermented vegetables.
Stay with liquids or a bland diet (plain rice, bananas, dry toast or crackers, applesauce) until you are feeling better.
The diverticulitis flare will usually go away after four to six weeks, Doerfler says. At that point, you can start eating higher-fiber foods like whole grains, fruits and vegetables, and healthy fats like nuts, seeds, avocado, and olive oil.
“Eggs are a great source of protein, and they're easily digested,” Dr. Nazarian says. And they won't irritate your diverticula.
In about 95 out of 100 people, uncomplicated diverticulitis goes away on its own within a week. In about 5 out of 100 people, the symptoms stay and treatment is needed.
Eggs contain protein that can be easily digested, and it will not irritate your digestive tract. Therefore, scrambled eggs can be taken during diverticulitis.
You may have heard advice that people with diverticular disease should avoid small, sharp and hard foods such as nuts, seeds and corn. The thinking is that there is a risk of undigested remnants of these foods lodging in the diverticula and causing inflammation.
Fresh fruits, like apples, have the most fiber when eaten with the skin. 13 However, if you're having symptoms of diverticulitis, look for lower-fiber options, like applesauce. Bananas are another good source of fruit fiber.
If your diet is currently low in fibre then it is advisable to increase fibre gradually; aim to introduce 1-2 new high fibre foods per week. It is recommended that adults aim for 30g of fibre a day. Foods High in Fibre: Weetabix®, Bran flakes, All Bran, Fruit & Fibre, porridge, muesli, Shredded Wheat.
When you are recovering from diverticulitis, you should eat cheese as a low-fiber food. The inflammation that causes cheese cravings must be treated to help prevent future attacks. If you have intestinal issues such as diverticulitis, you can usually manage symptoms by eating a low-fiber diet.
The UCSF noted that it is safe for people living with diverticulitis to eat nuts, popcorn, and seeds, including pumpkin and sesame seeds. Experts also say that it is OK to eat the seeds in tomatoes, zucchini, cucumbers, strawberries, and raspberries.
The doctor also may suggest taking a fiber product, such as Citrucel® or Metamucil®, once a day. Your doctor may recommend a low- or high-fiber diet depending on your condition. Listed below are high-fiber food options for diverticulosis and low-fiber food options for diverticulitis.
