Crohn’s Friendly Foods: What Should I Eat

oatmeal as a crohn's friendly food

Crohn’s disease is one of the conditions that those with Inflammatory Bowel Disease (IBD) suffer from. According to the Centers for Disease Control, the prevalence of IBD is estimated at 1.3% (3 million) of US adults. 

Crohn’s disease usually affects the ileum and colon, but can affect any area of the intestinal tract, from the mouth to the anus. Inflammation typically exists throughout the entire organ in Crohn’s Disease, rather than in patches like Ulcerative Colitis.  

Nutrition strategies for Crohn’s Disease are similar to Ulcerative Colitis. For more information about nutrition strategies for Ulcerative Colitis, refer to our latest article here

This feature aims to provide helpful information on what foods to eat for Crohn’s disease, why those foods would be of benefit, and some foods you might consider avoiding. 

Before we discuss nutrition strategies for Crohn’s Disease, let’s consider the differences between Crohn’s Disease and Ulcerative Colitis and some signs and symptoms of Crohn’s Disease. 

Risk factors, signs and symptoms of Crohn’s Disease

Crohn’s Disease is thought to result from an inappropriate inflammatory response to intestinal bacteria, where the immune system attacks the body’s healthy cells. 

When the bacteria mistakenly trigger the immune system, inflammation ensues causing symptoms of Crohn’s. Inflammation from Crohn’s Disease can also cause other issues like narrowing of the colon and abnormal connections between organs or surfaces. 

Similar to Ulcerative Colitis (UC), Crohn’s Disease is an idiopathic inflammatory condition marked by seasons of remission and flare. 

There are several risk factors associated with Crohn’s Disease, including: 

  • Family history – if you have a close relative with Crohn’s Disease, you are at higher risk of developing the disease yourself
  • Smoking – smoking may double your risk of developing Crohn’s
  • Certain medications – medications such as NSAIDs like aspirin or ibuprofen may increase your risk 
  • A high-fat diet – a high-fat diet, particularly a high animal fat diet may slightly increase your risk

Signs and symptoms of Crohn’s Disease 

The most common signs and symptoms of Crohn’s Disease include diarrhea, cramping, and abdominal pain, and weight loss. Others include: 

  • Chronic diarrhea
  • Fever
  • Rectal bleeding
  • Eye Inflammation
  • Failure to grow in children
  • Arthritis or joint pain 
  • Pallor (paleness)
  • Cachexia (disease-related wasting)
  • Nausea or loss of appetite 

Although there is no cure for Crohn’s Disease, having a nutrition strategy can help reduce overall inflammation, increase tolerance to foods, and reduce the risk of flare. 

A specialized IBD dietitian can help provide a nutrition prescription that fits into your lifestyle and helps you manage your disease. 

What to eat with Crohn’s 

In recent years, the use of nutrition therapy for IBD has significantly grown in interest. This is due to the fact that food is both a risk factor and a therapeutic option in IBD. Diet is a powerful tool alone and when used in conjunction with medical interventions. 

Here at the Crohn’s and Colitis Dietitians, we focus on:

  • Choosing foods that will help reduce inflammation and risk of flare
  • Choosing foods that will easily fit into your lifestyle and increase the quality of life

Before addressing foods for Crohn’s, it’s important to remember that the foods that trigger symptoms don’t always trigger inflammation.

 As well as the opposite, an inflammatory diet pattern doesn’t always immediately result in symptoms. It may be helpful to review our previous article, the 4 types of remission

Similar to UC, the best type of diet pattern for Crohn’s is a plant-based diet that’s rich in omega 3-fatty acids. Discussed below are some foods that are helpful for people with Crohn’s Disease:

Omega 3 Fatty Acids

Omega 3 fatty acids have known anti-inflammatory properties that can help reduce inflammation in Crohn’s disease. 

Increasing Omega 3 fatty acids in the diet increase the cell membrane content of these fatty acids, resulting in higher concentrations of inflammatory mediators ultimately reducing inflammation. 

Omega 3 fatty acids are rich in foods like fatty fish (salmon, tuna, trout), walnuts, and seeds like chia and flax.

Nut butter

As mentioned above, many of those with Crohn’s Disease lose a considerable amount of weight without trying to. 

According to a study in the Journal of Gastroenterology, weight loss is a significant issue in Crohn’s Disease with 57% of subjects experiencing significant weight loss prior to diagnosis. 

Including foods like nut butter can be a resourceful and satisfying way to increase caloric intake while also modifying the fiber type.  

Oatmeal

Incorporating foods like oats in the form of oatmeal can be a nourishing choice. Oatmeal is rich in soluble fibers.

Soluble fibers can help in increasing beneficial short-chain fatty acids and enhancing stool consistency. Oatmeal is especially helpful in times of flare! 

Olive Oil

Olive oil is rich in polyphenols, which are fascinating plant compounds known for their health-promoting properties. 

One such property is their ability to regulate the human immune system. We suggest forms of olive oil highest in polyphenols, our favorite is cold-pressed extra virgin olive oil. 

Antioxidant-rich foods

Incorporating antioxidant-rich foods helps defend against further tissue injury in IBD and disrupts the perpetuation of inflammation in the gut (Lih-Brody et al, 1996, Kruldenier and Verspaget, 2002). 

We suggest adding brightly colored berries, leafy greens, and other vegetables like butternut squash to smoothies since it’s an easy and delicious way to incorporate more antioxidants into your diet. 

Some of our favorite antioxidants to recommend include: 

  • Proanthocyanidins – dark grapes, red rice
  • Anthocyanins – blueberries, black currants, raspberries, black rice, purple/blue corn 
  • Chlorophyll – leafy greens, swiss chard, spinach, watercress, lettuce, celery
  • Carotenoids – butternut squash, sweet potatoes, tomatoes, peppers

What to eat when in a Flare 

While everyone is slightly different in the types of foods they tolerate in a flare, many are surprised by the number of foods they can tolerate when food quality is increased and known inflammatory food triggers are eliminated. 

All of the recommendations above are still applicable in a flare, however, we recommend working closely with an IBD specialized dietitian to focus on strategies to decrease inflammation and expand your diet. 

We understand that a flare is a really scary place to be in, but we want to encourage you not to over restrict foods. Over restricting foods can lead to poor nutrient status and reduce our body’s ability to repair itself. 

Even so, we understand how difficult that actually is – remember, we are both patients and practitioners! Start slow, remind yourself of the importance of sustenance and nourishment, and work your way up. 

Creating a list or booklet of flare friendly foods and recipes can be a helpful tool that eliminates anxiety during that time. This list could even be housed digitally for easier access, such as in the notes section of your phone. A few of our favorites include: 

  • Green bananas
  • Overnight oats
  • Beans
  • Smoothies
  • Roasted root vegetables like butternut squash and sweet potatoes
  • Stir Fry
  • Roasted salmon with black rice and green beans
