Are Diets Effective in Treating Crohn's Disease?


Crohn's disease is a type of inflammatory bowel disease (IBD) marked by chronic inflammation and irritation of the digestive tract. With around 3 million Americans affected by IBD, finding effective treatments is crucial. While there is no known cure for Crohn's disease, managing symptoms and controlling inflammation is possible. In this article, we will explore whether diets can be effective in treating Crohn's disease and discuss various dietary approaches that may help improve gut health.


The Link between Diet and Crohn's Disease

Although the exact cause of Crohn's disease remains unknown, factors such as genetics, immune system response, and environmental triggers are believed to play a role. Diet is thought to be one such environmental factor that can influence the development and progression of the disease.

It's important to understand that while specific foods or diets might not cause Crohn's disease, certain dietary habits can aggravate symptoms or trigger flare-ups. Identifying and avoiding these problematic foods can help manage the condition. Some potential culprits include high-fiber foods, fatty foods, dairy products, and carbonated beverages.

Nutrient Needs and Deficiencies

People with Crohn's disease often experience nutrient deficiencies due to inflammation interfering with nutrient absorption. Moreover, avoiding certain foods can lead to a lack of essential nutrients. As a result, it's vital for individuals with Crohn's disease to consume a nutrient-rich diet with adequate calories, protein, and healthy fats.

Steroid medications, commonly prescribed for Crohn's disease, may increase the risk of osteoporosis. Therefore, it's essential to ensure sufficient intake of calcium, vitamin D, magnesium, and vitamin K for bone health. Malabsorption may also result in deficiencies in vitamin C, vitamin B12, folic acid, and zinc.

Dietary Approaches for Crohn's Disease

Various diets have been proposed to help manage Crohn's disease symptoms. While there is no one-size-fits-all solution, some individuals may find relief by adopting specific dietary approaches. Here, we will discuss four diets that have been studied for their potential benefits in treating Crohn's disease.

1. Mediterranean Diet

The Mediterranean diet emphasizes the consumption of fresh fruits, vegetables, nuts, fish, and whole grains, with olive oil as the main cooking oil and spread. Studies have shown that this diet may lower the risk of developing Crohn's disease. Additionally, the Mediterranean diet has been ranked as the best overall diet by US News and World Reports in terms of nutrition, safety, ease of following, and benefits for conditions like diabetes and heart health.

A recent study comparing the Mediterranean diet to the Specific Carbohydrate Diet (SCD) in treating Crohn's disease found that both diets were effective in achieving symptomatic remission in around 40% of participants. Furthermore, over 30% of participants experienced improvement in internal disease activity markers at six weeks into the study.

2. Specific Carbohydrate Diet (SCD)

The Specific Carbohydrate Diet eliminates most sugars and grains and has been shown in smaller studies to improve active Crohn's disease. The same study mentioned earlier found that the SCD was equally effective as the Mediterranean diet in reducing symptoms and improving intestinal health.

3. Enteral Nutrition

Enteral nutrition involves consuming a liquid drink as the primary or sole source of nutrition for 8-12 weeks. This approach has been used primarily in children and teenagers with considerable success, particularly in Canada and Europe.

4. Crohn's Disease Elimination Diet (CDED)

The CDED is a combination of the Specific Carbohydrate Diet and enteral nutrition, with a strong emphasis on removing emulsifiers. This diet has shown promising results in managing Crohn's disease symptoms.

5. Auto-Immune Diet

The Auto-Immune Diet is similar to the Mediterranean Diet, Specific Carbohydrate Diet, and CDED in that it encourages the consumption of fresh fruits and vegetables while eliminating processed foods. This diet aims to reduce inflammation and improve overall gut health.

Personalizing Your Diet for Crohn's Disease

Given that no single diet is universally effective for everyone with Crohn's disease, it's essential to tailor your dietary approach to your individual needs and preferences. Working with a registered dietitian nutritionist experienced in digestive health can help you develop a personalized eating plan.

Some general tips and guidelines for managing Crohn's disease through diet include:

  • Keeping a detailed food diary to identify potential triggers
  • Gradually introducing new foods and monitoring their effects on your symptoms
  • Consuming smaller, more frequent meals
  • Staying hydrated by drinking plenty of water
  • Limiting or avoiding alcohol and caffeine
  • Taking vitamin and mineral supplements as needed, under the guidance of a healthcare professional
