Leaky gut, or increased intestinal permeability, occurs when the tight junctions of the gut lining become compromised. This allows undigested food particles, toxins, and microbes to escape into the bloodstream, where they can trigger immune responses and inflammation.

Leaky gut is believed to contribute to conditions like autoimmune disorders, allergies, mood issues, and chronic inflammation—especially in those with environmental sensitivities or CIRS.

Common triggers include highly processed foods, alcohol, NSAIDs, chronic stress, and food sensitivities. Healing the gut lining requires a multi-faceted approach: removing irritants, supporting digestion, and promoting repair.

Key dietary supports include bone broth, rich in collagen and amino acids; glutamine-rich foods like cabbage and poultry; and anti-inflammatory staples like turmeric, ginger, and leafy greens. Fermented foods and prebiotics can support microbial balance, while eliminating food triggers like gluten, dairy, or processed sugars may help reduce inflammation and reactivity.
