Answer From Katherine Zeratsky, R.D., L.D. 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.
Eating more whole fruits (as opposed to sauces and juices) and especially apples, pears and prunes resulted in the lowest risk of developing diverticulitis. Fiber from vegetables, beans and lentils was also associated with a reduced risk of the infection.
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.
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.
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.
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.
Diverticulosis: What to Eat. Cater says people with diverticulosis can benefit from eating fiber-rich foods, including: Whole grains, such as quinoa, bulgur, teff, barley, popcorn, oats, shredded wheat or bran cereals, and whole grain breads. Beans and legumes, including black beans, kidney beans, chickpeas and lentils.
Several drugs are associated with an increased risk of diverticulitis, including steroids, opioids and nonsteroidal anti-inflammatory drugs, such as ibuprofen (Advil, Motrin IB, others) and naproxen sodium (Aleve).
Stay with liquids or a bland diet (plain rice, bananas, dry toast or crackers, applesauce) until you are feeling better.
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.
“Eggs are a great source of protein, and they're easily digested,” Dr. Nazarian says. And they won't irritate your diverticula.
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.
Eggs contain protein that can be easily digested, and it will not irritate your digestive tract. Therefore, scrambled eggs can be taken during diverticulitis.
If you have diverticulosis
The main changes are adding fiber and drinking more water. Fiber absorbs water as it travels through your colon. This helps your stool stay soft and move smoothly. Water helps this process.
You can get some fluids from the foods you eat—especially foods with high water content, such as most fruits and vegetables. Water is the best beverage choice to stay hydrated. Avoid or limit sugar-sweetened beverages, including regular soda, fruit drinks, sports drinks, energy drinks, and sweetened coffee and tea.
CAUSES. The most commonly accepted theory for the formation of diverticulosis is related to high pressure within the colon, which causes weak areas of the colon wall to bulge out and form the sacs. A diet low in fiber and high in red meat may also play a role.
“Generally speaking, inflammation from diverticulitis can cause scar tissue formation and breakdown of the colon wall, and if the colon wall develops a hole, then an abscess will form,” warns Will Bulsiewicz, MD, a gastroenterologist and gut health expert in Mount Pleasant, South Carolina.
You can add vegetables to the foods that you are eating or have soup, salad or cooked vegetables on the side; Increasing your fiber intake slowly; And taking in enough fluids along with the high fiber foods. Go for water, seltzer, club soda, and herbal teas.
High fiber foods include: Fruits, such as tangerines, prunes, apples, bananas, peaches, and pears. Tender cooked vegetables, such as asparagus, beets, mushrooms, turnips, pumpkin, broccoli, artichokes, lima beans, squash, carrots, and sweet potatoes. Lettuce and peeled potatoes.
As long as you are not in the acute phase of diverticulitis, it's OK to eat nuts, corn and popcorn. 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.
