Healthy Way to Approach Diet in IBD If you have Crohn's disease or ulcerative colitis, collectively known as inflammatory bowel disease (IBD), you may be wondering "What can I eat?"In this video, Brittany Rodgers, MS, RD, CPT shares healthy ways to approach diet for Crohn's and colitis patients.
Foods to Consider Limitingin Diet
It is important to remember that people with IBD may have different experiences with food, and it does not affect everyonein the same way. Each person may even make diet choices depending on what may be going on with their disease, whether they may be in the midst of a flare, or in remission.
For some patients, there can be certaintrigger foods. There are alsofoods associated with increasing risk for active disease. Some patients may choose to minimize certain foods in their diet, but it is always helpful to consult with your doctor, and a dietitian about your needs.
Trigger foods:
Trigger foods are any food that causes unpleasant symptoms. Although they can lead to symptoms, trigger foods don’t necessarily cause harm (or inflammation) to your body. Everyone may have different trigger foods, although here are some common trigger foods and beverages:
- Foods high in insoluble fiber (does not dissolve in water) can be hard to digest: raw kale, skin of an apple, sunflower seeds
- High-fiber foods: Brussels sprouts, cabbage, cauliflower, asparagus
- High lactose-containing foods: cow’s milk, cream, ice cream, custard
- Sugar alcohols and artificial sweeteners: sorbitol, mannitol, xylitol, sucralose, aspartame, saccharin
- Added sugars and sugary foods: cookies, pastries, coconut sugar, honey, maple syrup
- High-fat foods: butter, cheesy dishes, fried foods
- Spicy foods: sriracha, chili powder
- Alcohol
- Caffeinated coffee/tea, energy drinks, other caffeinated beverages
- Sugar-sweetened beverages: soda, coffee/espresso drinks with sugar/syrup, juices
Foods associated with increased risk for inflammation:
Eating certain foods frequently over time has been found toincrease the risk for inflammation1. It’s okay to have these foods occasionally when you desire them, just have them in moderation. Instead of actively trying to restrict these foods, try to focus on adding more variety into your diet. For example, if you usually eat red meat every day, focus on adding a greater variety of protein into your diet so that you have chicken, turkey, tofu, eggs, tilapia, salmon, and tuna throughout the week.
Foods associated with increased inflammation include:
- Red meat: beef, lamb, pork, veal, bison
- Processed meat: lunch/deli meat, bacon, hot dogs, sausages
- Coconut oil, dairy fat, palm oil
Emerging evidence suggests the following foods may play a role in inflammation (although more research is needed):
- Processed foods containing certain additives:carboxymethylcellulose, polysorbate-80, carrageenan, maltodextrin, titanium dioxide, sulfates, guar gum
- Artificial sweeteners: aspartame, sucralose, saccharin
Important points to keep in mind:
- Be kind to yourself. It’s what your diet looks like as a whole, rather than a single day or meal, that makes the biggest difference. You can eat foods that may play a role in inflammation occasionally.
- Disordered eating is common in people with GI diseasesand is associated with worse disease outcomes2. If you feel your relationship with food could be better, reach out to an IBD-focused dietitian and gut-specialized psychologist.
- Some cultures frequently consume spicy foods or red meat. Instead of completely eliminating these traditional foods from your diet, try adapting recipes to swap out ingredients for better tolerated alternatives. You can also try eating less of the food so that you can still enjoy it but it doesn’t trigger symptoms.
Foods to Increase in Your Diet
When consumed frequently over time, certain foods have been found to decrease inflammation1.
Foods to increase in your diet include:
- Fruits: bananas, raspberries, applesauce, blended fruit
- Vegetables: squashes, fork-tender cooked carrots, green beans
- Foods rich in omega 3 fatty acids: fatty fish (salmon, tuna, mackerel, etc.), walnut butter, chia seeds, flaxseed oil, flaxseed meal
Other healthy foods to include in your diet:
- Cooked and cooled or reheated starches: potatoes, sweet potatoes, rice, oatmeal
- Leafy green vegetables (try cooking and cutting into small pieces or blending them into smoothies)
Worried about not being able to digest fruits and vegetables?
Think about the type, texture, and amount of the fiber-containing food.
Type:
Can the fruit/vegetable dissolve in water quickly? If so, it’s likely to be high in soluble fiber. Raspberries are the perfect example. As soon as you drop a fresh raspberry into a glass of water, it will start to disintegrate. If a fruit/vegetable won’t dissolve in water, such as the skin of an apple, it’s high in insoluble fiber. Insoluble fiber can cause more frequent or urgent trips to the bathroom.
Texture:
At times, it may be helpful to adjust the texture of the food. For example, raw kale and blended kale both contain the same amount of insoluble fiber, but blended kale is much better tolerated as it acts more like soluble fiber in the intestines. Instead of raw nuts, nut butters may be easier to digest.
Amount:
Instead of adding a lot of fruits and vegetables into your diet at once, which can increase frequent and urgent trips to the bathroom, try slowly adding them a little at a time.
For individuals with stricturing Crohn's disease:
Depending on how symptomatic you are, you may need to adjust the amount and/or texture of other foods, not just those that contain fiber. Some examples of foods that could be problematic include:
- Mushrooms
- Popcorn
- Steak
- Dried meats or fruit
- Raw nuts
- Salads
Food Preparation and Planning
While there is no one-size-fits-all for meal planning, these tips can help guide you toward better daily nutrition:
- Stay hydrated—drink enough to keep your urine light yellow: water, broth, a smoothie, an enteral nutrition supplement, or an oral rehydration solution (hydrating beverage containing sugar and electrolyte salts)
- Prepare meals in advance
- Plan some quick and easy meals for days you’re too tired to cook bigger meals
- Keep your kitchen stocked with foods that don’t aggravate your symptoms
- Use simple cooking techniques: boil, grill, roast, steam, poach
- Create a plan for eating outside the home: review menus ahead of time, let friends/family members know if you prefer to bring your own meal to gatherings or holidays, and adapt cultural/religious recipes so that you can enjoy these special occasions
How Should I Eat When Flaring?
In general, it would be good to continue consuming the foods listed in the “foods to increase in your diet” section. You may also need to adjust the texture of fiber-containing foods to improve tolerance.

What to Eat When in a Flare When you have inflammatory bowel diseases (IBD), and are in the middle of a flare, it is very important to avoid foods that may trigger additional symptoms and choose foods that are healing and nutritious. Watch and listen to learn more on dietary recommendations when in a flare.
Resist self-imposed restrictive diets:
Unless your doctor or dietitian has instructed you to follow a specific diet and you’re getting adequate support, resist the urge to follow diets recommended to you by friends, family, or people on the internet. Just like medications, restrictive diets have potential side effects that can include nutrient deficiencies, unplanned weight loss/malnutrition, disordered eating, or progression to an eating disorder, all of which may negatively impact disease outcomes.
Increase protein:
Since protein needs increase during active disease, it’s also helpful to focus on consuming protein-containing foods throughout the day. Some examples of foods containing protein are chicken, tofu, fish, turkey, eggs, yogurt, beans, chia seeds, and nut butters.
Increase fluids:
If you’re having frequent loose stools, have a fecal infection, or have constipation or incomplete evacuation, it may be helpful to focus on increasing hydrating fluids. Some examples of hydrating fluids are water, broth, smoothies, and an oral rehydration solution.
Nutrient dense meals/snacks:
If your appetite has decreased, you’ve lost weight without trying recently, or have a fecal infection, it may be helpful to consume frequent, small, nutrient-packed meals or snacks.
Some examples include:
- Adding a snack (e.g., 1 tablespoon of peanut butter and a banana, hummus and crackers, or yogurt and berries)
- Adding olive oil to meals
- Adding ¼ to ½ an avocado to meals
- Having a smoothie between meals
- Adding sauces to meals (such as a lemon garlic tahini sauce)
Minimize food restrictions:
If you feel restricted, your diet is likely lacking variety. Every whole food contains different nutrients, so when you restrict a food, and especially a food group, from your diet, you’re at risk for nutrient deficiencies. Since this can negatively impact your disease, try to minimize food restrictions. If you’re unsure of what to eat and what is triggering your symptoms, work with an IBD-focused registered dietitian.
How Should I Eat When in Remission?
If you were adjusting the texture of foods during your flare, you can start reintroducing tougher-to-digest foods when you’re in remission. If you have stricturing Crohn’s disease, ask your doctor whether you should continue adjusting the texture of foods. Some trigger foods will only cause symptoms during active disease and others will be triggers regardless of disease activity.
Try to keep your diet as expansive as possible, especially including as many tolerated plant-based foods as possible, such as fruits, vegetables, nuts, seeds, herbs, and whole grains. Continue to consume plenty of foods that reduce the occurrence of active disease and minimize those that may lead to increased occurrences of active disease.

Eating When in Remission When you are in remission with inflammatory bowel diseases (IBD), it is very important to focus on maintaining a diverse and nutrient rich diet. Watch and listen to learn more on dietary recommendations when in remission.
In remission but still have symptoms?
Reach out to an IBD-focused registered dietitian to help you find your trigger foods. They may suggest a low-FODMAP diet, if appropriate.
