Foods that Can Damage Your Gut Lining and Cause Inflammation

Your gastrointestinal (GI) tract is lined with a single layer of cells that form a critical barrier between your gut and the rest of your body. This intestinal wall controls what gets absorbed from your food and keeps out toxins, allergens, and microbes that can cause inflammation or infection. Certain foods can damage your gut lining, leading to increased intestinal permeability or “leaky gut.” This allows undigested food particles to enter your bloodstream and trigger widespread inflammation.

FOODS TO AVOID TO HEAL YOUR GUT

Gluten

Gluten is a protein found in wheat, barley, and rye. It can damage the microvilli hair-like projections on intestinal cells that aid digestion and nutrient absorption. This can cause inflammation, flatten the villi, and lead to malabsorption issues. Those with celiac disease or gluten sensitivity are at highest risk for gluten-induced leaky gut.

Sugar and Refined Carbs

A diet high in sugar and refined carbs like white bread, pasta and cookies feed bad gut bacteria which release inflammatory compounds. The spike in blood sugar also generates free radicals and (advanced glycation) end products which damage cell membranes. This increases intestinal permeability.

Artificial Sweeteners

Artificial sweeteners like aspartame, sucralose, and saccharin negatively alter gut flora, allowing harmful bacteria to flourish. They also irritate the intestinal lining. Studies show regular consumption of artificial sweeteners causes leaky gut symptoms like inflammatory bowel disease.

Processed and Fried Foods

Fast food, chips, nuggets, and other processed foods are loaded with fat, salt, and chemical additives that promote inflammation. Deep fried foods contain (advanced glycation) end products that directly damage gut barrier proteins. They also contain emulsifiers that disrupt mucus membranes.

Alcohol

Drinking heavily can loosen the tight junctions between your intestinal cells, allowing endotoxins, bacteria, and undigested food particles to leak through into your bloodstream. This provokes widespread inflammation and systemic immune responses. Chronic alcohol use increases leaky gut and susceptibility to liver disease.

Non-Organic Meats and Produce

Pesticides, hormones, antibiotics, and other chemicals used in conventional agriculture leave residue on and in non-organic produce and factory farmed meats. These compounds damage intestinal villi and disrupt good bacteria, promoting leaky gut. Always opt for organic food when possible.

Soy, Dairy, and Eggs

These common allergens can damage the intestinal lining and provoke leaky gut for those who are sensitive. Especially problematic are conventionally-raised dairy and eggs, and GMO and processed soy products like tofu and soybean oil. Opt for organic, fermented, or sprouted versions whenever possible.

To heal a damaged gut lining, remove these inflammatory foods for 30-90 days. Follow an anti-inflammatory diet focused on organic produce, grass-fed meats, wild-caught fish, nuts, seeds, healthy oils, bone broth, and fermented foods to provide gut-healing nutrition. Consider adding gut-repairing supplements like zinc, vitamin A, probiotics and L-glutamine. Get checked for food sensitivities and work with a holistic nutritionist to identify your unique triggers. With time and diligent diet changes, you can heal your leaky gut, seal your intestinal barrier, and reduce whole-body inflammation.
