Diverticulosis of the colon is a common condition affecting many Americans. Diverticulosis is not the same as diverticulitis. Most people over age 50 have diverticulosis although it may occur earlier in life. Diverticulosis is the presence of out pouchings (diverticula) that develop on the wall of the large intestine (colon). They occur at weak areas on the colon wall and are most often found on the left side (sigmoid colon), but can be found throughout the colon.

Most people with diverticulosis have no symptoms. Some patients with diverticulosis can have painless rectal bleeding although there are many other causes for this. 10–25% of patients with diverticulosis will go on to develop diverticulitis which is inflammation and perforation of a diverticulum. This may cause left sided and lower abdominal pain, fevers, and changes in bowel habits.

Legumes: The bean family excels in fiber, especially the soluble, cholesterol-lowering type. They include kidney, pinto, navy, lima, and baked beans.

Whole Grains: Wheat bran and oat bran are present in a variety of cereals and breads. The label should say that the bread contains whole wheat or whole grain. Plain wheat bread may lack fiber. One cannot always tell by the color. Some manufacturers artificially color bread brown to make it look more wholesome.

Whole Fresh Fruits: Valuable pectin fiber is found in the skin and pulp. Figs, prunes, and raspberries have the highest fiber content.

Cooked or Stewed Fruits: Prunes and applesauce are good choices.

Green Leafy Vegetables: Spinach, celery, and broccoli are good examples.

Root Vegetables: Potatoes, turnips, and carrots are excellent sources.

Since fiber can cause rumbling intestinal gas and even some mild cramping, the amount taken should be increased gradually. The goal should be 25 to 35 grams of fiber each day, which will usually produce one to two soft, formed stools per day. Learn more about high fiber diets here.
