Diverticulitis Diet: Foods to Eat And Foods to Avoid

Diverticulitis is a medical condition characterized by the inflammation or infection of small pouches, known as diverticula, which can form in the intestinal walls—a condition referred to as diverticulosis. Though the initial presence of diverticula is typically benign, it can lead to diverticitis, which ranges in severity from minor infections or abscesses to more serious complications such as bowel perforations. Management of the condition may include dietary adjustments, as specific foods can help improve symptoms or should be avoided during flare-ups to prevent aggravation of the condition.

Good or Bad: High Fiber Foods

According to Healthline, incorporating foods high in fiber could potentially ameliorate diverticulitis symptoms and serve as a preventative measure. This assertion is supported by a 2017 study review. However, Healthline also advises that individuals experiencing a flare-up of diverticulitis may need to moderate their fiber consumption, as not all patients respond well to high fiber intake under these circumstances. The rationale is that fiber increases stool bulk and can lead to heightened colon contractions, which might exacerbate symptoms. It is recommended to consult with a healthcare professional for personalized advice regarding dietary adjustments during such episodes.

Good: Low-Fiber Foods

It is essential to recognize the role of dietary fiber in maintaining overall health, yet during episodes of diverticulitis-related discomfort, a low fiber diet is advisable, as indicated by Healthline. Suitable food choices during such flare-ups encompass white rice, pasta, refined fruit products, carefully cooked fish or eggs, peeled potatoes, and juices devoid of pulp. Conversely, one should steer clear of high-fiber foods like beans, legumes, whole grains, and uncooked fruits or vegetables when experiencing aggravated symptoms.

Bad: Fruit/Vegetable Skins

According to Reader's Digest, individuals experiencing a diverticulitis flare-up and adhering to a low-fiber diet should consider peeling fruits and vegetables to reduce fiber intake. They recommend opting for canned or cooked produce, which typically has a lower fiber content compared to its raw counterparts. Additionally, it's advisable to steer clear of foods such as nuts, seeds, legumes—including snow peas—and whole grains to align with the dietary restrictions of this condition.

Bad: FODMAP Foods

FODMAPs are a group of carbohydrates that are highly fermentable and found in various foods, such as apples, pears, plums, dairy products, fermented goods, beans, cabbage, onions, and garlic. According to Healthline, these include oligosaccharides, disaccharides, monosaccharides, and polyols. Research suggests that a diet low in FODMAPs may provide relief for individuals with irritable bowel syndrome (IBS) and may also be beneficial during a diverticulitis flare-up.

Good: Clear Liquids

When managing diverticulitis, a clear liquid diet is often recommended to alleviate discomfort by minimizing digestive workload. Reader's Digest highlights that this dietary approach aims to lessen stool volume and inflammation. Acceptable clear liquid options include clear broths, water, herbal teas, apple juice, and plain gelatin.

Good: Full Liquid Diet

Reader's Digest highlights that the next phase of the diverticulitis diet typically begins after several days on a clear liquid regimen, expanding dietary options. In addition to clear liquid diet items, this stage incorporates milk, pudding, thickened soures, and cooked cereals for added variety. Smooth ice cream, butter, and frozen yogurt may also be permissible. Furthermore, liquid nutritional supplements can be considered, but should only be included following the advice of a dietitian and with a doctor's approval.

Good: Fermented Foods

EveryDay Health asserts that incorporating foods with "active cultures" into one's diet may benefit individuals with diverticulosis and diverticulitis, and could potentially aid in prevention. Fermented foods like yogurt, kimchi, miso, kombucha, and kefir are recommended for promoting improved digestion and mitigating constipation often linked with diverticulosis. Furthermore, these foods may bolster the immune system and provide additional health advantages, including a reduced risk of conditions like diabetes.

Good or Bad: Nuts, Seeds, Popcorn

According to Healthline, historical medical advice typically recommended that patients with diverticular conditions abstain from consuming nuts, seeds, and popcorn due to concerns that small particles from these foods could become trapped in intestinal pouches, potentially leading to infection. However, contemporary medical perspectives are evolving away from this conservative dietary restriction. Recent studies have not demonstrated a significant correlation between the intake of these foods and the exacerbation of diverticulitis symptoms, suggesting that such caution may no longer be necessary.

Bad: A ‘Western’ Diet

According to Healthline, the prevalent North American diet, characterized by elevated levels of fat and sugar coupled with insufficient fiber, may be contributing to the increased incidence of diverticulitis. Studies indicate that by limiting the intake of specific foods such as red meat, refined grains, full-fat dairy, and fried foods, individuals can potentially reduce their risk of developing diverticulosis or mitigate the symptoms associated with diverticulitis.

Good: Avoiding Future Flare-Ups

Diverticulitis Diet: Foods to Eat And Foods to Avoid 10

Reader's Digest suggests that, after a period of illness and upon consultation with your healthcare providers, you may gradually reintroduce fiber into your diet. Once you receive medical guidance and clearance, it's recommended to steadily increase your fiber consumption toward the daily recommended intake of 25 to 35 grams. Adhering to a high-fiber diet when asymptomatic can aid in preventing future health complications. However, caution is advised regarding the potential adverse effects of high fiber during active symptoms. Additionally, it is beneficial to engage in regular physical activity and maintain proper hydration, ideally drinking up to 12 glasses of water per day.
