Diverticulitis Diet: Ten Foods to Avoid

2. Whole grains

Again, these are foods normally recommended by physicians, dietitians, trainers etc. When going through the throes of diverticulitis, though, the rules must change for the sake of the colon. In addition to the fiber, iron and B-vitamins found in legumes, whole grains offer zinc, antioxidants and phytochemicals. The fiber content of bran, whole wheat, brown rice or oats, for example, expands the volume of the stool which, in turn, prevents the diverticula from returning to a normal state.


The severity of inflammation increases as high-fiber foods continue to travel the length of the colon.
