A diverticulitis diet is best for people with gut inflammation. Typically, consumption of foods low in dietary fiber leads to the formation of tiny pouches (diverticula) in the innermost walls of the colon. When these tiny diverticula get inflamed or infected, they cause pain and bleeding. This condition is termed diverticulitis.

Diverticulitis And Fiber-Rich Foods How It Helps

Fiber is a type of carbohydrate that cannot be digested by humans. Fiber is of two types, soluble and insoluble, depending on its ability to dissolve in liquids. Both soluble and insoluble fiber are of great importance as they help add bulk to the stool, slow down the transition time of digested foods in the colon, help in the absorption of nutrients, suppress appetite, and help good gut bacteria to flourish, which improves digestion (363a.html' target='_blank' rel='noopener noreferrer' >2) (3).

Without fiber, you can suffer from constipation, and the colon has to work extra hard to pass the stool leading to diverticulosis or bulging of the colon wall. Consuming foods that are rich in fiber can help prevent your colon from exerting pressure to excrete the stool, thereby preventing irritation of the colon walls. But ensure you do not consume too many high-fiber foods too soon.

You should be very careful while incorporating fiber-rich foods into your diet. How to do it right? Follow our diverticulitis diet plan that will not shock your colon but instead help you make a smooth transition. Take a look.
