Keto Diet: A Solution For Crohn's Disease?

Crohn's disease is an inflammatory bowel disease characterised by flare-ups, which are periods of exacerbated symptoms. Flare-ups are often triggered by particular foods. There is no cure for Crohn's disease, and standard treatment involves steroids, immunosuppressants and biological therapy to reduce symptoms. However, some people have found success in alleviating their symptoms through diet.

The ketogenic (keto) diet is a low-carb, high-fat diet that has been used to treat epilepsy. The keto diet is not recommended for Crohn's disease by some experts, as it restricts carbohydrates and B vitamins and encourages the consumption of cheese, butter, seeds and fibrous vegetables. However, others argue that the keto diet can reduce inflammation in the body and improve the gut's microbiome.

A case report published in the International Journal of Case Reports and Images describes how a 14-year-old boy with severe Crohn's disease successfully treated his condition with a paleolithic ketogenic diet, which consists of animal fat, meat, offal and eggs. After two weeks on the diet, the patient was able to discontinue medication and remained symptom-free for 15 months.

While the paleolithic ketogenic diet may not work for everyone, this case report provides an example of how dietary changes can be used to manage Crohn's disease.

The keto diet may reduce inflammation in the body and improve the gut's microbiome

The ketogenic diet, or keto diet, is a high-fat, low-carbohydrate diet that has been used to treat epilepsy in children for over a century. The keto diet is often recommended to reduce inflammation in the body and improve the gut microbiome, which may be beneficial for those with Crohn's disease.

Crohn's disease is an inflammatory bowel disease characterised by periods of exacerbated symptoms called flare-ups, which can be triggered by certain foods. While there is no cure for Crohn's disease, dietary interventions have been shown to reduce symptoms and medications.

The keto diet may help reduce inflammation in the body by altering the gut microbiota and metabolites. A study on mice with inflammatory bowel disease found that a keto diet reduced inflammatory responses, protected the intestinal barrier function, and decreased the production of inflammatory cytokines and group 3 innate lymphoid cells. The keto diet also led to an increase in Akkermansia, a type of bacteria associated with improved glucose homeostasis and protection of the intestinal barrier. Additionally, the keto diet can contribute to beneficial weight control, as it was found to control weight gain in mice before colitis induction.

The keto diet may also improve the gut microbiome by reducing the abundance of Escherichia/Shigella, a genus of bacteria dominant in high-fat diets and associated with increased susceptibility to colitis. The diet can also increase the abundance of Roseburia, a type of bacteria associated with weight loss and improved glucose tolerance.

However, it is important to note that the keto diet may not be suitable for everyone with Crohn's disease. The diet restricts carbohydrates and encourages the consumption of cheese, butters, seeds, and fibrous vegetables, which may trigger symptoms during a flare-up. It is always recommended to consult with a healthcare professional before starting any new diet, especially if you have a medical condition.

The paleo diet may reduce inflammation in the body

The paleo diet is an anti-inflammatory diet that aims to remove sugar, legumes, most dairy, grains, and refined vegetable oils like corn and soy oil. It gets its name from its focus on the foods ancient hunter-gatherers relied on. The diet includes wild and uncultivated plant and animal sources such as lean meat, fish, vegetables, fruits, eggs, and nuts. It excludes grains, legumes, dairy, salt, refined sugar, and processed oils.

The paleo diet avoids pro-inflammatory foods like refined carbohydrates, wheat, and other cereal grains, soda, and other sugar-sweetened beverages, margarine, shortening, and lard, and processed meats. These types of food can alter gut health and cause insulin spikes, which contribute to inflammation.

The paleo diet promotes anti-inflammatory foods like fruits and vegetables, which are rich in natural antioxidants and protective compounds called polyphenols. It also promotes a more natural omega fatty acid balance, which has an anti-inflammatory effect on the body and can improve cardiovascular health.

Some studies suggest that the paleo diet offers benefits like weight loss and increased energy. There is also anecdotal evidence that eliminating inflammatory foods in the standard American diet can help manage diseases like Crohn's disease, ulcerative colitis, rheumatoid arthritis, psoriasis, and multiple sclerosis.

However, critics argue that more research is needed to determine the effectiveness of the paleo diet in treating autoimmune diseases. Some experts caution that the restrictive nature of the paleo diet may lead to more risks than benefits, including nutrient deficiencies.

In conclusion, while the paleo diet may help reduce inflammation in the body, it is important to consult with a healthcare professional before adopting any new diet, especially for those managing a chronic illness like Crohn's disease.

The keto diet is restrictive and may cause nutrient deficiencies

The keto diet is a high-fat, low-carbohydrate, and moderate-protein eating plan. It is restrictive in nature and may cause nutrient deficiencies.

The keto diet is restrictive in that it requires a reduction in carbohydrates to less than 20-50 grams per day. This means that common carbohydrate-rich foods such as grains, legumes, fruits, and starchy vegetables are limited or eliminated. While the keto diet does allow for some low-carbohydrate fruits and vegetables, the variety is limited, and it may be challenging to ensure adequate intake of all essential nutrients.

The restrictive nature of the keto diet can lead to nutrient deficiencies. Specifically, it may be lacking in carbohydrates and B vitamins. The diet's emphasis on high-fat foods and limited intake of fruits and vegetables can result in insufficient intake of vitamins, minerals, fiber, and phytochemicals. These include thiamin, folate, vitamins A, E, B6, calcium, magnesium, iron, potassium, vitamin K, linolenic acid, and water-soluble vitamins, excluding vitamin B12.

Additionally, the keto diet's restriction of grains, legumes, and fruits can reduce the intake of dietary fiber, which is essential for healthy intestinal function and the production of beneficial short-chain fatty acids by the gut microbiota. A diverse and healthy gut microbiota is crucial for maintaining overall health and reducing the risk of various diseases.

Furthermore, the keto diet's restriction of certain food groups can lead to an inadequate intake of protective dietary components such as phytochemicals, flavanones, and anthocyanins, which are typically not included in multivitamins and lack specific intake targets.

To avoid potential nutrient deficiencies while on the keto diet, it is essential to carefully plan your meals and include nutrient-dense foods. It may also be beneficial to consider taking supplements to ensure adequate intake of all essential vitamins and minerals.

In conclusion, the keto diet's restrictive nature, which limits or eliminates certain food groups, can lead to nutrient deficiencies. To mitigate this risk, it is crucial to carefully plan your meals, include a variety of nutrient-dense foods, and consider taking supplements under the guidance of a healthcare professional.

The paleo diet may cause nutrient deficiencies

The paleo diet, also known as the Paleolithic diet, is based on the idea that our bodies are best fuelled by foods that existed in the Paleolithic era, before agriculture came along 10,000 or so years ago. The diet includes wild and uncultivated plant and animal sources such as lean meat, fish, vegetables, fruits, eggs, and nuts. It excludes grains, legumes, dairy, salt, refined sugar, and processed oils.

However, it is important to note that the paleo diet is a nutrient-dense diet, and deficiencies may be avoided by carefully selecting foods. For example, caviar, liver, and green vegetables are rich sources of multiple nutrients and can be included in the paleo diet.

In addition, the paleo diet in combination with the ketogenic (keto) diet has been found to successfully treat Crohn's disease in at least one case report. The paleolithic ketogenic diet consists of animal fat, meat, offal, and eggs, with a 2:1 fat-to-protein ratio. This diet resulted in the resolution of symptoms, normalization of laboratory parameters, and gradual normalization of bowel inflammation in a patient with severe Crohn's disease.

The keto diet is not recommended by dieticians

The keto diet is a very low-carbohydrate, high-fat diet that can be difficult to maintain and lacks essential nutrients. According to Christine Allen, a registered dietician, it is "not the best idea for Crohn's". This is because the keto diet is lacking in carbohydrates and B vitamins, and encourages the consumption of cheese, butters, seeds, and fibrous vegetables. During a symptom flare-up, it is important to choose low-fiber foods, and when in remission, it is crucial to eat a variety of healthy foods. The keto diet may not provide the necessary variety of nutrients to achieve this balance.

The keto diet's emphasis on high-fat foods and low to moderate amounts of protein can also be problematic. Opponents of the keto diet, including registered dietitian Eleanor Baker, caution that such a diet can lead to excessive weight loss and problems with cholesterol, blood pressure, and cardiovascular disease. The high-fat content may also increase the intake of fatty or fried foods and milk products, which can trigger Crohn's symptoms.

Furthermore, the keto diet's restriction of carbohydrates can reduce the consumption of easily digestible complex carbohydrates that are important for energy, such as low-fiber fruits and refined grains. It may also be challenging to meet nutritional needs while on the keto diet, and supplementation should only be done under medical supervision.

While some people have reported improvements in their Crohn's symptoms after adopting a keto diet, there is currently insufficient clinical research to support its effectiveness for this purpose. As such, it is always advisable to consult with a healthcare professional before making significant dietary changes, particularly when managing a complex digestive condition like Crohn's disease.
