A condition where the intestinal barrier becomes compromised, allowing undigested food particles, toxins, and bacteria to pass into the bloodstream
General information about how people eat, not medical advice. Talk to a clinician before changing your diet to treat a condition.
The Paleo diet removes potential gut-irritating foods like grains and legumes, which can contribute to intestinal permeability. By emphasizing nutrient-dense, anti-inflammatory foods, the diet supports gut healing and reduces intestinal inflammation.
How Eliminating potential gut-damaging foods and introducing healing nutrients helps repair intestinal lining and reduce inflammatory responses. The diet's focus on gut-healing compounds supports mucosal repair and reduces intestinal permeability.
Key foods Bone broth, grass-fed beef, wild-caught fish, organic eggs, fermented vegetables, turmeric, ginger, coconut oil
The elimination of potential inflammatory and allergenic foods combined with nutrient-rich whole foods helps repair intestinal lining and reduce gut permeability. The diet provides specific nutrients that support gut mucosal healing.
How By removing potential gut irritants and providing high levels of glutamine, zinc, and omega-3 fatty acids, the diet supports intestinal epithelial cell repair and reduces inflammatory responses that contribute to increased intestinal permeability.
Key foods Bone broth, collagen-rich foods, chia seeds, pumpkin seeds, organic leafy greens, wild-caught fish, fermented vegetables
The Elimination Diet is specifically designed to heal intestinal permeability by removing foods that damage tight junctions between intestinal cells, including gluten, dairy, and processed foods. The emphasis on nutrient-dense, anti-inflammatory whole foods provides the building blocks necessary for intestinal repair, including amino acids, zinc, and omega-3 fatty acids. Most people experience significant gut healing within 4-6 weeks, with reduced systemic symptoms like fatigue, brain fog, and skin issues.
How Gluten and other inflammatory food proteins can increase zonulin production, a protein that regulates intestinal tight junctions, leading to increased permeability. The diet removes these triggers while providing L-glutamine from bone broth and protein sources that help repair the intestinal lining. Anti-inflammatory compounds reduce intestinal inflammation, allowing tight junctions to restore their barrier function and preventing systemic endotoxemia.
Key foods Bone broth, wild-caught salmon, leafy greens like spinach, sweet potatoes, olive oil, blueberries, quinoa, grass-fed beef
The Neanderthal Diet eliminates common gut-irritating foods like grains and legumes while providing nutrient-dense foods that support gut lining repair. Its focus on whole foods helps reduce intestinal inflammation and supports microbiome health.
How By removing potential gut-damaging compounds and providing nutrients that support intestinal cell repair, the diet helps reduce intestinal permeability. The high nutrient density and elimination of inflammatory foods allow the gut lining to heal and restore proper barrier function.
Key foods Bone broth, grass-fed beef, wild-caught fish, pasture-raised eggs, fermented vegetables, coconut oil, turmeric, ginger
SCD is specifically designed to heal intestinal permeability by eliminating foods that damage the gut lining and providing nutrients that support gut repair. The diet's removal of complex carbohydrates reduces bacterial overgrowth and the production of toxins that damage tight junctions between intestinal cells. Patients typically experience improved gut barrier function within months, leading to reduced systemic symptoms like fatigue, joint pain, and skin issues.
How The diet heals leaky gut through multiple mechanisms: providing easily digestible nutrients that don't stress the damaged intestinal lining, eliminating foods that feed bacteria producing gut-damaging toxins, and supplying building blocks like amino acids from bone broth for tight junction repair. The probiotic-rich yogurt helps restore beneficial bacteria that support gut barrier integrity, while the anti-inflammatory whole foods reduce ongoing damage to the intestinal wall.
Key foods Bone broth rich in collagen and glutamine, 24-hour fermented yogurt, wild-caught fish with omega-3s, organic eggs, cooked non-starchy vegetables, grass-fed meats, almond butter, honey
By removing potential gut irritants like grains, legumes, and dairy, the Paleo diet helps reduce intestinal inflammation and supports gut lining repair. The diet provides nutrients that directly support gut healing and microbiome health.
How The elimination of inflammatory food groups reduces gut wall irritation and allows for cellular repair. The diet provides high levels of glutamine, collagen, and other gut-healing nutrients that support intestinal lining integrity and reduce permeability.
Key foods Bone broth, grass-fed beef, wild-caught fish, fermented vegetables, coconut oil, eggs, turmeric
AIP diet directly targets intestinal permeability by eliminating foods that can damage the gut lining and introducing healing nutrients. The protocol helps seal the intestinal walls, reduce inflammation, and restore proper gut barrier function.
How By removing inflammatory foods like grains, legumes, and nightshades, the diet reduces ongoing gut irritation. The nutrient-dense foods provide collagen, glutamine, and other compounds that directly support intestinal cell repair and strengthen the gut barrier.
Key foods Bone broth, grass-fed beef, wild-caught fish, fermented foods like kimchi, coconut oil, turmeric, ginger, leafy green vegetables
