Diverticulitis is a digestive condition characterized by inflammation and irritation of small pockets in the colon lining, known as diverticula. These pockets form when the colon muscles weaken, a condition called diverticulosis. The risk of diverticulosis escalates with age, affecting approximately 70% of individuals aged 80 and above. Managing diverticulitis often involves dietary adjustments to alleviate symptoms and prevent future flare-ups. This article explores the potential relationship between the carnivore diet and diverticulitis, considering available research and expert opinions.
Understanding Diverticulitis
Diverticulitis flare-ups can be extremely painful. Acute flare-ups are typically managed with a clear fluid and low-residue diet for several days to allow the gut to heal. The cause of diverticulosis and diverticulitis is complex and not fully understood.
The Carnivore Diet: An Overview
The carnivore diet involves consuming only animal-based foods, completely excluding plant-based foods. Many proponents of this diet focus on red meat.
Red Meat Consumption and Diverticulitis Risk
A 2020 study indicated that higher meat consumption was associated with a slight increase in the risk of developing acute diverticulitis. This association was particularly evident with unprocessed red meat, such as beef, lamb, pork, and hamburgers. However, the same study noted that higher consumption of poultry (white meat) did not appear to elevate the risk of acute diverticulitis.
Potential Risks of a Carnivore Diet for Diverticulitis
Given the association between red meat and diverticulitis risk, a carnivore diet high in red meat could potentially increase the risk of developing diverticulitis or worsen existing symptoms. Therefore, individuals with diverticulitis should exercise caution when considering a carnivore diet.

The Role of Fiber
Traditionally, inadequate fiber intake was believed to be the primary cause of diverticulosis. Vegetarian and vegan diets are often cited as advantageous due to their high fiber content compared to the typical Western diet. However, recent research suggests that a high-fiber diet (specifically, high in FODMAPs) may be linked to Irritable Bowel Syndrome (IBS) symptoms, adding complexity to the dietary recommendations for diverticulitis.
The FODMAP Connection
Minimizing problem FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) may be beneficial for diverticulitis patients. Portion sizes of low-FODMAP foods are crucial in a diverticulitis diet, and exceeding recommended portions should be avoided.
The Importance of Probiotics
Research suggests that various probiotic strains are effective in managing diverticulitis symptoms. Probiotics have been successfully combined with the anti-inflammatory drug Mesalamine to help reduce symptoms. Probiotic supplements are a viable option, although recommended strains and dosages are still under investigation. Some evidence suggests that specific strains of lactobacilli may be particularly useful in treating symptoms.
Nuts, Seeds, and Other Foods
Conflicting information exists regarding the consumption of nuts, seeds, corn, popcorn, and fruits and vegetables with seeds. While some believe these foods should be avoided, current scientific evidence clashes with patient reports. It may be prudent to err on the side of caution and avoid seeds, at least temporarily.
Other Dietary Considerations
There is little evidence to suggest that cutting meat, nuts, or seeds from the diet is beneficial. However, individual experiences vary.

Is a Carnivore Diet Suitable?
The carnivore diet may not be suitable for individuals with diverticulitis, especially if it heavily relies on red meat. Further research is needed to determine whether a carnivore diet focused on white meat could be a viable option.
Alternative Dietary Approaches
Dietary changes can help manage diverticulitis. During a flare-up, a clear fluid and low-residue diet are typically recommended. A high-fiber diet is generally associated with a reduced risk of developing diverticulitis, but it's important to consider the potential impact of FODMAPs.
Vitamin D and Diverticulitis
Unfortunately, natural food sources of vitamin D are not very useful if you have a deficiency.
