Study Description

The DINE-CD study seeks to compare the efficacy of two different dietary strategies to reduce symptoms and inflammation in Crohn's disease. The two diets being studied are the Mediterranean style diet and the Specific Carbohydrate Diet (SCD). Participants will be assigned to one of the two diets for a 12 week period. During the first six weeks, participants will be provided with all of their food. For the last six weeks, participants will be asked to follow the diet on their own (with the option to purchase some or all of their meals from the same vendor providing food during the first six weeks). During the duration of the study, participants will complete three study visits at one of the study sites located throughout the United States.

Description of Treatment or Intervention (Mechanism of Action)

  • A Mediterranean style diet is rich in fiber and plant-based food. It also includes olive oil, low fat dairy, herbs, and spices. Poultry, eggs, cheese, and yogurt are eaten in moderation, and red meat is eaten rarely. Research has shown that a Mediterranean style diet has numerous health benefits, including reducing the risk of heart disease and lowering cholesterol as well as reducing incidence of cancer and Parkinson's and Alzheimer's diseases. 
  • SCD eliminates refined/processed foods and many type of carbohydrates as well as soy, lactose, sucrose, and grains, and certain vegetables such as potatoes, okra and corn. This diet can be low in certain nutrients, such as B vitamins, calcium, vitamin D, and vitamin E.

Patient Participation Requirements

18 years old or older, mild to moderate Crohn's disease, stable dose of medications prior to screening.

Possible Risks & Side Effects

Your Crohn's Disease may not get better or may get worse while on study. Additionally, with any research study, a breach of confidentiality may occur.
