Diverticulosis is a very common colon condition in which small pouches form on the colon wall. Most people who have diverticulosis have no symptoms, However, sometimes one of the pouches gets inflamed, usually due to a bacterial infection.

To reduce your risk of getting diverticulosis and diverticulitis, add high-fiber foods to each meal. Aim for up to half your plate to contain some fiber-rich food.

Here are some tips that can help you make the transition to a higher-fiber diet.

Eat a minimum of three servings of vegetables and two servings of fruit every day. This makes up the five-a-day recommended by the USDA’s Dietary Guidelines for Americans. In general, one serving is a single piece of fruit or a half-cup of raw fruits or vegetables, or a cup of leafy greens.
Include fruits, vegetables, or both with every meal. For instance, include fruit with breakfast and as a snack, and vegetables with lunch and dinner.
Eat pulses (the seeds of plants in the legume family), such as beans, lentils, and peas, at least three times a week. You can include them either as a plant-based protein in meatless dishes, or as the starch side in place of grains. For example, you could have fish on a bed of lentils rather than rice.
Rely on nuts, seeds, and fruit for snacks. Or add them to other items like yogurt, oatmeal, salads, and stir-fries.
Replace refined grains like white rice with whole grains like brown rice, wild rice, or bulgur. For pasta, look for versions made from quinoa or pulses like chickpeas and lentils.
Check nutrition fact labels for the amount of dietary fiber. Aim for at least 5 grams of fiber per serving.

Be careful about eating a lot of fiber at once. Overdoing it can cause gas, bloating, diarrhea, and abdominal cramps as your gut bacteria try to process all the new fiber. These problems go away after a while as your digestive system gets used to the higher fiber levels, but you can avoid them by adding extra fiber gradually to your diet.

For example, try to add just one more serving of a high-fiber food to your daily diet for a week, then see how your body feels. Give yourself another week, if needed. If everything is okay, add another daily serving for a week. Continue this pattern until you reach your daily quota of fiber.

Also, make sure to drink plenty of fluids each day—about 16 ounces of water, four times a day. Increasing the water you drink can help fiber pass through your digestive system and avoid stomach distress.
