Harvard research shows gliadin (the protein in gluten) triggers leaky gut in every single person who eats it, not just celiacs. Your gut uses a receptor called TLR-4 to detect dangerous pathogens. Gliadin looks close enough to a bacterial toxin that TLR-4 misfires, releasing a protein called zonulin that physically unlocks your gut lining. In healthy people, the gut reseals quickly. But glyphosate, sprayed directly on wheat before harvest, decimates Lactobacillus and Bifidobacterium, the bacteri
