Irritable bowel syndrome (IBS) is a common gastrointestinal disorder affecting a significant portion of the population. Characterized by abdominal pain, bloating, and irregular bowel habits, IBS can significantly impact one's quality of life. While there's no single cause, inflammation appears to play a key role in the development and exacerbation of IBS symptoms. An anti-inflammatory diet has emerged as a promising strategy for managing IBS, aiming to reduce inflammation and promote gut health.
Understanding Inflammation and IBS
Inflammation is a natural immune response to injury or infection, signaling the body to initiate healing. However, chronic inflammation, a prolonged and excessive inflammatory response, can damage healthy cells and contribute to various health conditions, including IBS. Research suggests that chronic inflammation exacerbates IBS symptoms.
The Anti-Inflammatory Diet: A Lifestyle Modification
The anti-inflammatory diet is not a specific regimen but rather an overall eating style focused on consuming foods that help reduce inflammation in the body. It emphasizes whole, minimally processed foods rich in nutrients like polyphenols, antioxidants, and fiber. Unlike the low FODMAP diet, which is a short-term elimination diet, the anti-inflammatory diet is intended as a long-term lifestyle modification.
Key Components of an Anti-Inflammatory Diet
An anti-inflammatory diet prioritizes several key components:
- Minimizing processed foods: Avoiding packaged snacks, sweets, and processed meats.
- Increasing dietary fiber intake: Consuming plenty of fruits, vegetables, whole grains, legumes, nuts, and seeds.
- Incorporating omega-3 fatty acids: Including fatty fish like salmon, tuna, and mackerel in the diet.
- Including lean proteins: Choosing lean protein sources from both plant and animal-based sources.
- Implementing various spices: Utilizing spices like turmeric and cinnamon, which have anti-inflammatory properties.
This diet works to minimize the intake of trans and saturated fats, which can contribute to inflammation in the body and a pro-inflammatory state.

Benefits of an Anti-Inflammatory Diet for IBS
An anti-inflammatory diet may help with IBS symptoms by:
- Neutralizing free radicals: Foods high in antioxidants may lower inflammation in the gut by removing free radicals that can cause inflammation and oxidative damage.
- Supporting beneficial bacteria: Anti-inflammatory diets provide fuel and nutrients that support beneficial bacteria while inhibiting the growth of harmful bacteria. Studies link IBS to dysbiosis or an imbalance in gut bacteria.
- Increasing the production of SCFAs: Fiber, omega-3 fatty acids, and polyphenol-rich foods support the production of short-chain fatty acids (SCFAs). SCFAs are fermentation products that help maintain the balance of gut bacteria and regulate inflammation in the gut.
The Mediterranean Diet: A Specific Approach
If you are looking to follow a more specific approach to the anti-inflammatory diet, then it is recommended to follow a Mediterranean Diet approach, which prioritizes many of the anti-inflammatory dietary guidelines discussed. The Mediterranean diet is a popular anti-inflammatory eating pattern that includes all of the above foods plus olive oil, small amounts of dairy, and red wine in moderation. It's high in monounsaturated fats and fiber-rich plant-based foods, which studies show may help reduce inflammation in the body.
Combining the Low FODMAP Diet with Anti-Inflammatory Foods
Integrating a low FODMAP or anti-inflammatory diet can be done separately or in combination for maximum benefits. If your GI symptoms are triggered by unknown food intolerances, it may be best to first start with a low FODMAP elimination diet. Ideally, the maintenance phase of the FODMAP approach would be a great place to add back in anti-inflammatory foods for symptom management. By identifying food-related triggers with the low FODMAP diet and then incorporating anti-inflammatory foods, individuals may achieve significant relief from their digestive discomfort and IBS.
Personalizing Your Anti-Inflammatory Diet
Even anti-inflammatory diets need to be personalized to the individual. It's estimated that almost 90 percent of people with IBS link symptoms like pain or bloating with food intake, and food triggers can vary from person to person. This is why personalized elimination diets are important for gut conditions like IBS.
Here are some tips to help you personalize an anti-inflammatory diet:

- Book an appointment with a registered dietitian to receive professional guidance.
- Keep a food journal and track symptoms after eating or drinking.
- Modify your favorite recipes to better fit your IBS requirements.
What works for one person may not work for another-especially since there are different subtypes of IBS with varying symptoms. Low-fiber or low-FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) diets are often used to help with symptoms because these foods are often poorly absorbed by people with IBS, but they also temporarily remove many foods emphasized on an anti-inflammatory diet. The goal for any elimination diet is to slowly reintroduce as many foods as possible, but it can take time for symptoms to subside. In the meantime, even if a food is considered anti-inflammatory, it may not be right for you at that moment, but eventually, you may be able to tolerate it.
Anti-Inflammatory Foods to Include
Throughout the article, we have identified foods that are anti-inflammatory, with a wide variety of foods identified to be plant-based food choices. The great news is that many foods are considered to have anti-inflammatory benefits, and the key is to have variety and as many colors in the diet as possible for maximum benefit.
- Fruits: Apples, berries, avocados, oranges
- Vegetables: Leafy greens, peppers, broccoli
- Lean protein: Chicken, turkey, plant-based proteins
- Fatty fish: Salmon, tuna, herring, mackerel
- Whole grains: Brown rice, wild rice, oats
- Legumes: Dried beans, peas
- Nuts and seeds: Walnuts, flaxseeds, chia seeds
- Spices: Turmeric, cinnamon
- Healthy oils: Extra virgin olive oil (EVOO)
Sample Anti-Inflammatory Meal Plan for IBS
Here's a sample meal plan incorporating anti-inflammatory foods that may be suitable for individuals with IBS. Remember to adjust portion sizes and ingredients based on your individual needs and tolerances.
Breakfast
- Oatmeal or cream of rice with fresh berries and a sprinkle of cinnamon.
- Smoothie bowl made with non-dairy milk, protein powder, banana, spinach, and ground flaxseed.
Lunch
- Quinoa salad with roasted vegetables, chickpeas, and a lemon-tahini dressing.
- Grilled chicken salad with mixed greens, cherry tomatoes, and balsamic vinaigrette.
Dinner
- Grilled salmon with roasted veggies and sweet potato wedges.
- Brown rice pasta with tomato sauce, ground turkey, sautéed mushrooms, and spinach.
Snacks
- Rice cakes with peanut butter and sliced banana.
- Carrots and cucumbers with hummus.
Additional Considerations
- Probiotics: IBD patients should consider consuming supplements or foods containing probiotics in their daily diet for lower risk of IBD adverse effects. However, research on the effectiveness of probiotics as a treatment for IBD is limited and emerging. As there were many variations among available studies, further research is required to determine the most suitable probiotic strains, dosing regimens of probiotics and specific population of IBD patients who can benefit from probiotic supplementation. Probiotics should be considered as a part of a patient’s healthcare besides medications, nutritional intervention, and lifestyle management.
- Prebiotics: This study demonstrated that patients with quiescent UC should increase their fiber intake with the consumption of a diet rich in oat bran. Germinated barley foodstuff (GBF) is a type of prebiotic which is composed of mainly fibers (cellulose, hemicellulose, and lignin) and some proteins and lipids as dietary compounds
