Avoiding constipation and straining by eating a high fiber diet could help prevent diverticulitis, according to WebMD. A regular exercise schedule and adequate water intake can help impede constipation and reduce the chance of developing diverticulitis. Stopping smoking and avoiding non-steroidal anti-inflammatory drugs can forestall diverticulitis complications, explains Everyday Health.
The diverticulitis diet recommends eating 20 to 35 grams of fiber per day, notes Everyday Health. It is important to consume a mixture of insoluble and soluble fiber, as found in foods such as beans, vegetables, fruits and whole grains. Add psyllium or methylcellulose fiber supplements to your daily diet if you cannot eat the recommended amount of fiber due to dietary restrictions.
Avoid overeating red meat if you want to prevent diverticulitis, suggests Everyday Health. Fatty foods may also cause intestinal blockages or increase diverticulitis symptoms. Once doctors believed that eating nuts, seeds and popcorn could cause infection in people with diverticulitis, but that theory was disproved, notes Healthline.
When having a diverticulitis attack, your doctor may recommend consuming a clear liquid diet, according to Healthline. A clear liquid diet consists of foods such as water, broth, gelatin, and tea or coffee without added flavoring. The doctor may then recommend a low-fiber diet until you no longer have any symptoms, after which you can resume a high-fiber diet.
