Intestinal Permeability (Leaky Gut)

Autoimmune Protocol (AIP)

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.

Key foods: Bone broth, grass-fed beef, wild-caught fish, fermented foods like kimchi, coconut oil, turmeric, ginger, leafy green vegetables

How does Autoimmune Protocol (AIP) assist with Intestinal Permeability (Leaky Gut): 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.

Cave Man Diet

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.

Key foods: Bone broth, grass-fed beef, wild-caught fish, organic eggs, fermented vegetables, turmeric, ginger, coconut oil

How does Cave Man Diet assist with Intestinal Permeability (Leaky Gut): 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.

Detox Diet

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.

Key foods: Bone broth, collagen-rich foods, chia seeds, pumpkin seeds, organic leafy greens, wild-caught fish, fermented vegetables

How does Detox Diet assist with Intestinal Permeability (Leaky Gut): 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.

Stone Age Diet

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.

Key foods: Bone broth, grass-fed beef, wild-caught fish, fermented vegetables, coconut oil, eggs, turmeric

How does Stone Age Diet assist with Intestinal Permeability (Leaky Gut): 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.

Neanderthal Diet

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.

Key foods: Bone broth, grass-fed beef, wild-caught fish, pasture-raised eggs, fermented vegetables, coconut oil, turmeric, ginger

How does Neanderthal Diet assist with Intestinal Permeability (Leaky Gut): 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.

Elimination Diet

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.

Key foods: Bone broth, wild-caught salmon, leafy greens like spinach, sweet potatoes, olive oil, blueberries, quinoa, grass-fed beef

How does Elimination Diet assist with Intestinal Permeability (Leaky Gut): 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.
