Diet don’ts for diverticulosis patients may change

Posted August 26, 2008

For years, doctors have warned people with diverticulosis to stay away from foods like popcorn, nuts or corn because they may raise the risk of more bleeding in the colon.

Now, researchers have found that diverticulosis patients may not need to avoid those foods after all.

A third of all Americans will develop diverticulosis – small pockets in the colon – by age 60. If the pockets become infected, it can lead to a more serious condition called diverticulitis.

“It can be serious. It can lead to operations, surgery, colon perforations – death, even, in rare instances,” said gastroenterologist and study author Dr. Sapna Syngal, of Brigham and Women's Hospital in Boston.

Researchers at Brigham and Women’s analyzed data from more than 47,000 men. Questionnaires were used to monitor what the men ate and their medical condition every two years. Researchers specifically looked at the link between eating things like popcorn, nuts and corn and the incidence of diverticulitis.

“To our surprise, there was no association with nut, popcorn or corn intake and the development of diverticulitis or diverticular bleeding,” Syngal said.

Participants were followed for 18 years. Men who ate popcorn, nuts and corn more than twice a week were no more likely to develop the disease than those who only ate those food less than once a month.

The study appears in the Journal of the American Medical Association.

“The people who had higher intakes of nuts and popcorn had a lower rate of diverticulitis. So it actually went against what has been believed for a long period of time,” Syngal said.

Researchers believe the findings may also hold true for women, but can't say for sure until studies involving women are conducted.

Doctors don't have the answer for how to avoid complications from diverticulosis. Further studies are needed to see if certain foods may actually protect you from developing diverticulitis.

    I had a bout with diverticulosis recently, and to quote my doctor, the old fashioned thought process about nuts, seeds, and popcorn was an "old wives tale". Basically, it is without scientific was an acceptable diagnosis doctors came up with back in the 30s and 40s, and went unchallenged until recently.

    These foods might not all cause it but I know for sure that peanuts, okra, popcorn and even blueberries - can cause an onset of this condition. It is one of the most painful things I have ever had.

    read carefully this article is misleading. eating the foods doesnt cause diverticulitis to occur, but it still aggrevates the condition.

    Diverticulitis is agrevated by eating nuts and foods with seeds because the seeds can get caught within the folds of the diverticulum. Foods dont cause the problem but they do agrevate the condition.

    I've dealt with this since I was 14. I was lucky that I wasn't forced to deal with an ostomy after surgery. Eating certain foods like those or raw green veggies (brocolli etc) still hurt so I'll keep avoiding them.

    Glad to read this article. After a colonoscopy last year I was given a restrictive diet because of diverticulosis and haven't eaten nuts, berries, popcorn, etc. since then. 'Can't wait until I go grocery shopping again.

    OUCH! I have had two bouts with this and it is VERY painful. I put it right up there with appendicitis.
