The ancient Greek physician Hippocrates is credited with the famous quote, “Let food be thy medicine and medicine be thy food.” Though there is no historical evidence to support that Hippocrates actually said this, the quote has been important in highlighting the role of diet in disease prevention, treatment, and management. A nutritionally sound diet may provide therapeutic benefits in managing chronic conditions such as Crohn’s disease. Though diet is not a cure, it may increase the efficacy of medicinal treatments when used in collaboration with them. (Source)
Inflammatory bowel disease may flare up during times of high stress, when you use non-steroidal anti-inflammatory drugs (NSAIDs) or take antibiotics that alter gut bacteria, if you don’t take your medications as prescribed, and last but not least, when you eat foods that irritate your digestive system. Certain foods may aggravate the gastrointestinal tract, making symptoms such as chronic diarrhea worse, especially during a flare. Learning how proper nutrition affects you will help you manage your disease better. (Source)
Reducing severity and occurrence of Crohn’s flares through dietary intervention may help you manage and reduce disease symptoms. Managing and improving your symptoms may mean avoiding trigger foods that may increase GI inflammation. A standard Western diet tends to be high in refined sugars and processed foods and, unfortunately, low in fruits and vegetables.
This lack of fresh food along with reduced fiber intake can have a negative effect on the digestive system. Consuming the typical Western diet is not feasible for maintaining a healthy microbiome and may contribute to the development of inflammatory bowel disease. The following are some foods you might want to avoid with Crohn’s disease. (Source, Source, Source)
Note this list is fairly extensive and includes some foods that, while they may exacerbate Crohn’s symptoms, also provide health benefits. Be sure to work with your health care provider or WellTheory Care Team to ensure your diet is nutritionally sound and supportive of your autoimmune condition.
Refined sugar is found in most packaged and processed foods as well as in sweet beverages, such as sodas, that are carbonated or fizzy. A high sugar intake has been linked to increased risk of developing Crohn’s disease. (Source)
A Western diet is typically high in fats that may increase the risk of triggering or flaring inflammatory bowel diseases such as Crohn’s. Avoiding fast, fatty foods and fried, greasy foods is advised. Polyunsaturated fats are high in omega-6 fatty acids that may increase inflammation. Seed oils such as safflower, sunflower, soybean, corn, and cottonseed oil are high in omega-6 fatty acids. (Source, Source, Source, Source)
Caffeine may benefit some by promoting a daily bowel movement, but for those with Crohn’s, it has the ability to exacerbate diarrhea. Caffeine may cause reflux and reduce your appetite, contributing to malnutrition if you are already dealing with absorption issues. Caffeine may increase the risk of insomnia as well as increase the level of stress hormones. Besides coffee, chocolate and some kinds of tea contain caffeine and it may be beneficial to avoid them or reduce consumption. (Source)
Alcohol can be irritating and inflammatory to anyone’s intestines, but if you’re living with Crohn’s disease it can be extremely aggravating and tends to exacerbate symptoms and inflammation. (Source)
Consumption of gluten and grains may increase the risk of gut dysbiosis, leading to malabsorption and gut permeability. Limiting your intake or eliminating this category of foods altogether may improve intestinal inflammation and absorption. Following a gluten free diet is possible by avoiding gluten-containing grains such as wheat and rye, among others. (Source)
Consuming gassy foods that are difficult to digest due to a high fiber content may increase Crohn’s symptoms. Foods it may be best to avoid include beans and legumes, as well as cruciferous vegetables such as Brussels sprouts, broccoli, cauliflower, and cabbage. (Source)
Nuts and seeds can be difficult to digest in general, but for those with impaired digestion it may be extra difficult. Nuts and seeds that are in their whole form may irritate the GI tract, but you might be able to tolerate smooth nut and seed butters, which are gentler on the gut. (Source)
Spicy foods and seasonings have the ability to irritate even healthy intestines, but if yours are already inflamed, avoiding them may be wise. Spicy food triggers that may promote cramps and diarrhea include hot sauces or fiery spices such as chili powder or cayenne pepper. Specific diet strategies, such as the autoimmune protocol (AIP) diet, eliminate hot spices that promote inflammation. (Source)
Research has shown that the nutrients from food included in a healthy diet play a role in managing Crohn’s disease flare-ups and chronic inflammation. Not only are there many foods to avoid with Crohn’s, but there are also foods to include that can reduce inflammation and improve symptoms.
The gut microbiome is a key factor in the development and management of inflammatory intestinal disorders, and diet is directly linked to our internal environment. There are many specialized whole foods diets to manage Crohn’s symptoms, such as the Crohn’s Disease Exclusion Diet, the low FODMAP diet, and the AIP diet just to name a few. Read on to find out what nutrient-dense foods you can include in your diet to help manage your Crohn’s disease. (Source, Source)
Fermented foods such as kimchi, miso, and fermented pickled vegetables contain probiotics that are beneficial to building and maintaining a diverse gut microbiome for optimal health. Research has shown that traditional Japanese foods such as these may improve gut bacteria and support digestion, helping reduce symptoms of Crohn’s disease. (Source)
Bone broth is a nutrient dense food full of minerals, amino acids, and collagen, all of which are essential to good gut health. Research has shown that nutrient deficiencies may be a risk factor for the development of gastro intestinal symptoms. Filling in the gaps of nutritional and mineral deficiencies by including foods like bone broth could be a great tool to manage your disease as research shows it can improve symptoms and inflammation in ulcerative colitis, another form of irritable bowel disease.

Including as much plant diversity as possible in your diet (while avoiding the gas inducing vegetables above) is key to getting your essential nutrients. Raw vegetables may upset the GI tract, so consuming cooked vegetables could be your best bet. Removing skin and seeds of fruits may help alleviate aggravation of the gut lining and ease digestion as well. According to the AIP diet all fruits are acceptable to eat, as well as all vegetables (with the exception of corn and those classified as night shades). Suggestions for which fruits and vegetables to consume will vary depending on the diet you follow to manage symptoms or flares, and whether it is a low fiber or low fat diet. Your body may respond well to some fruits and vegetables and not to others, so taking a personalized approach to managing your symptoms is key. (Source, Source, Source, Source)
Red meat has been shown to increase the risk of relapse in some with inflammatory bowel disease, though consuming lean meats such as chicken, turkey, and fish have not been proven to increase the risk of developing or flaring disease symptoms. Though some healing diets such as the AIP diet do include red meat, that doesn’t necessarily mean you should either include it or cut it out — listen to your body and the recommendations of your Care Team to know what protein sources are best for you.
Please note: if you have Crohn’s you have a higher need for protein in take due to excess inflammation. Protein rich foods such high quality meat, fish, and eggs may help your body to heal more effectively. Personalizing your approach by writing in a food journal to keep track of what foods bother you and what foods help is important to learning how to manage your Crohn’s disease best.

Foods high in omega-3 fatty acids are good for reducing inflammation and include walnuts, fatty fish such as salmon, mackerel, and sardines, as well as olive and flaxseed oils. Including omega-3 fats in a balanced diet may reduce the risk of a Crohn’s flare-up. (Source)
