  • Incorporate beneficial microbes: Add fermented foods like yogurt and kefir, and prebiotic sources such as garlic and asparagus, to support a healthy gut microbiome.

  • Be mindful of fiber during flares: While fiber is beneficial in remission, certain types, especially insoluble fiber from raw vegetables and whole grains, may be irritating during active inflammation.

  • Limit processed and sugary foods: High-fat, processed foods, and added sugars can promote inflammation and should be minimized.

  • Consult a healthcare professional: Any dietary changes for high calprotectin should be made in consultation with a doctor or dietitian, especially for IBD management.

In This Article

Calprotectin is a protein released by certain white blood cells called neutrophils, and its level in stool (fecal calprotectin) serves as an important marker for inflammation in the gastrointestinal tract. Elevated calprotectin is a hallmark of inflammatory bowel diseases (IBD) like Crohn's disease and ulcerative colitis, but can also be raised in other conditions. While diet is not a cure, adopting a nutrition plan focused on reducing inflammation can be a powerful tool for managing symptoms and potentially lowering calprotectin levels.

Embracing an Anti-Inflammatory Diet

Many of the foods that help lower calprotectin are staples of an anti-inflammatory or Mediterranean-style diet. These foods are rich in nutrients that combat inflammation at a cellular level, helping to calm an overactive immune response in the gut.

Foods Rich in Omega-3 Fatty Acids

Omega-3s are polyunsaturated fatty acids known for their potent anti-inflammatory properties. They can help reduce the production of inflammatory molecules and balance the gut microbiota.

  • Oily fish: Salmon, mackerel, sardines, tuna, and herring are excellent sources of EPA and DHA, the most bioavailable forms of omega-3. Aim for at least two servings per week.
  • Flaxseed and Walnuts: These are rich in ALA, another omega-3 fatty acid. Ground flaxseed is particularly beneficial as it also provides a source of fiber.
  • Flaxseed oil and Canola oil: Can be used in cooking and dressings to increase omega-3 intake.

Colorful Fruits and Vegetables

Fruits and vegetables are packed with antioxidants and polyphenols that protect cells from damage and fight inflammation.

  • Berries: Blueberries, strawberries, and raspberries are rich in antioxidants.
  • Pomegranate: Pomegranate juice has been specifically studied for its potential to lower fecal calprotectin levels in IBD patients.
  • Leafy Greens: Spinach, kale, and other leafy greens are linked to lower inflammatory markers.
  • Broccoli and Cauliflower: These cruciferous vegetables contain compounds that aid in reducing inflammation.

Herbs and Spices

Certain herbs and spices possess powerful anti-inflammatory effects.

  • Turmeric: Contains curcumin, a compound with proven anti-inflammatory benefits that has been shown to reduce calprotectin in UC patients. Pairing it with black pepper significantly enhances absorption.
  • Ginger: Known for its anti-inflammatory properties and can be a soothing addition to a gut-friendly diet.

Understanding the Role of Fiber

Fiber's impact on gut inflammation can be complex and depends on whether the disease is active or in remission. During a flare-up, a low-fiber, low-residue diet may be recommended to give the bowel a rest. In remission, however, increasing fiber is crucial for feeding beneficial gut bacteria and promoting a healthy intestinal lining.

Soluble vs. Insoluble Fiber

  • Soluble Fiber: Dissolves in water to form a gel-like substance that can be very soothing for the digestive tract.
    • Sources: Oats, peeled apples and pears, root vegetables (carrots, potatoes), and legumes (as tolerated).
  • Insoluble Fiber: Adds bulk to stool but does not dissolve. It can be irritating during active inflammation.
    • Sources to be cautious with during flares: Whole grains, nuts, seeds, and raw vegetables.

The Gut Microbiome: Probiotics and Prebiotics

Modulating the gut microbiome is a key strategy for managing gut inflammation. High calprotectin is often associated with an imbalance in gut bacteria.

Probiotic-Rich Foods

Probiotics are live microorganisms that can help restore a healthy balance of gut bacteria.

  • Fermented Foods: Yogurt, kefir, kimchi, and sauerkraut are excellent sources. Choose refrigerated products with live and active cultures.
  • Strains: Specific probiotic strains, like those in VSL#3 (Visbiome™), have shown benefits in managing pouchitis and UC.

Prebiotic Foods

Prebiotics are types of fiber that feed the beneficial bacteria in your gut.

  • Sources: Chicory, garlic, onions, leeks, asparagus, bananas, and oats. Reintroducing these foods slowly after a flare can help rebuild a healthy microbiome.

Foods to Limit or Avoid

Some foods are known to promote inflammation and can exacerbate symptoms, potentially raising calprotectin levels.

  • Processed and High-Fat Foods: These can increase gut inflammation and are often high in omega-6 fatty acids, which can disrupt the omega-3 to omega-6 ratio.
  • Red and Processed Meats: Linked to increased inflammation. Focus on lean protein sources like fish and poultry.
  • Sugar and Artificial Sweeteners: Can fuel inflammation and negatively impact the gut microbiome.
  • Spicy Foods: Can irritate the gut lining, especially during a flare.
  • Alcohol and Caffeine: May trigger symptoms and should be limited or avoided during active disease.
  • Dairy (if lactose intolerant): Lactose intolerance can cause gas, bloating, and diarrhea, worsening symptoms.

Dietary Comparison: Beneficial vs. Potentially Harmful

Category Beneficial Foods Potentially Harmful Foods (Especially during flares)
Fats Oily fish, olive oil, walnuts, flaxseed oil Fried foods, high omega-6 vegetable oils, fatty red meats
Fruits & Veggies Cooked or peeled fruits, berries, pomegranate juice, leafy greens, cooked carrots, potatoes Raw fruits and vegetables with skins, sweetcorn, raw onions, broccoli (during flares)
Grains & Starches Oats, white rice, peeled potatoes Whole grains and bran during flares; high-fiber cereals
Proteins Oily fish, lean poultry, eggs, tofu Processed meats, red meat
Probiotics Yogurt, kefir, kimchi, sauerkraut Some dairy products if lactose intolerant
Spices Turmeric, ginger Spicy seasonings, chili powder
Beverages Water, fruit juice without pulp (in remission), ginger tea Alcohol, caffeine, sugary drinks, high-fructose fruit juices

Putting it all together

Managing calprotectin levels through diet is a long-term strategy that requires consistency and personalization. A diet rich in anti-inflammatory foods, balanced fiber, and supportive probiotics is a strong foundation. However, dietary needs can change, especially during flare-ups, and trigger foods are highly individual. Keeping a food diary can help identify specific culprits. A registered dietitian specializing in IBD or gut health can provide personalized guidance to help you navigate these changes safely and effectively.

Conclusion

While medical treatment is essential for managing conditions associated with high calprotectin, diet plays a crucial supportive role. By incorporating anti-inflammatory foods like oily fish, berries, and leafy greens, along with probiotics and prebiotics, individuals can help reduce gut inflammation. The approach to fiber should be tailored to disease activity, and processed, high-fat, and sugary foods should be minimized. A personalized nutrition plan, often developed with a healthcare professional, offers the best path forward for using diet to help lower calprotectin levels and support overall digestive health.
