Diverticulitis and Fiber

Diverticulitis and Fiber?noresize

Diverticular disease has two phases: a dormant phase and an active phase. Diverticulosis is characterized by the formation of small, bulging pouches called diverticuli in the intestine. Diverticulitis is the condition's active form.  Diverticulitis occurs when the pouches in your colon become infected or inflamed. Diverticulosis is actually a fairly common condition; 35% of the US population has it.

However, less than 5% of these people will experience diverticulitis in their lifetime. Because it is rarely expressed, most people with Diverticulosis will never even know they have it!  For those of you who have Diverticulosis, there are a few dietary recommendations that will help prevent diverticulosis from progressing to diverticulitis. These recommendations also align with our general recommendations for a healthy, balanced diet.

The Key Ingredient: Fiber

Our recommendations really focus on one key nutrient…fiber! The USDA’s fiber recommendation for adults is 25-30 grams per day. Despite this recommendation, research shows the average American adult only consumes 10-15 grams of fiber per day, less than half of the recommended amount!

Not eating enough fiber puts you at a much higher risk of developing Diverticulitis. Fiber helps to add bulk to your stool, which allows it to pass quickly and easily. This detail is important because constipation and straining during bowel movements can make your condition worse. Below are some easy tips for adding more fiber to your diet.

Eat whole fruits and vegetables instead of juice

Whole fruits and vegetables contain substantially more fiber than fruit juice itself. Most dietary fiber is found in the skin and the flesh of the fruits and vegetables, which is what is removed when extracting juice. For example, a whole orange contains about 3 grams of fiber, while one juiced orange contains only 0.5 grams.

Leave the skin on fruits and vegetables

Fruits and vegetables with the skin-on contain more fiber than their skinless counterparts. Researchers believe the difference can be up to 33% more for the skin-on version.

Read food labels

Whole foods are the best way to get fiber. However, when choosing packaged foods, look for brands that are rich in fiber. Some packaged foods even have fiber added to them, which is typically advertised on the product package. Any product containing 2.5 grams of fiber per serving is considered a “good” source, and anything with 5 grams or more per serving is considered “excellent”.

Choose whole grains

Whole grains are significantly higher in fiber than refined grains. During the refining process, the two parts of the grain that contain most of the nutrients, the bran and germ, are removed. The refined product is lower in overall nutrients and fiber. You will find examples of whole grains below.

If needed, take a fiber supplement

If you are eating a balanced diet rich in fruits and vegetables, you shouldn’t need to take a fiber supplement. However, some people can benefit from trying psyllium husk, Metamucil, or something similar. Be careful when adding a fiber supplement, though, as dramatic increases in fiber can cause discomfort.

The best way to increase your fiber intake is through whole foods. The list below highlights the foods with the highest fiber content. Choose a variety of these foods to incorporate into your daily diet.

Fruits: Pears, Strawberries, Avocado, Apples, Raspberries, Bananas, Blueberries, Blackberries

Vegetables: Carrots, Beets, Broccoli, Artichoke, Brussels Sprouts, Kale, Spinach, Tomatoes

Legumes: Lentils, Kidney Beans, Black Beans, Split Peas, Chickpeas, Edamame, Lima Beans, Quinoa

Grains: Quinoa, Oatmeal, Brown rice, Whole Wheat Pasta, Barley, Oat Bran
