In a person with ulcerative colitis and severe gut microbial imbalance, a 17-month dietary intervention that removed wheat, dairy, and refined sugars and added probiotics, lactoferrin, and...
Mechanism
Synthesis from 1 study
Cutting out wheat, dairy, and sugar starves bad bacteria. Probiotics push them out, lactoferrin steals their iron, and glutathione cleans up toxic chemicals. Vitamins and minerals fix the gut lining so bad bacteria can't live there anymore. The numbers drop because the environment becomes...
Most probable mechanism
Removing wheat, dairy, and refined sugars starves harmful bacteria by cutting off their food supply, while probiotics and lactoferrin directly compete with them and steal their essential iron. Glutathione neutralizes toxic chemicals produced by inflammation, and vitamins and minerals repair the gut lining. As the gut barrier heals, harmful bacteria can no longer survive or multiply, and their numbers drop sharply.
Removal of dietary antigens and fermentable carbohydrates reduces microbial fermentation substrates in the colon, suppressing overgrowth of iron-dependent and pro-inflammatory bacteria
Lactoferrin binds free iron in the intestinal lumen, depriving iron-dependent pathogens such as Escherichia spp. and Klebsiella pneumoniae of essential growth cofactors
Probiotic strains colonize the mucosal surface and outcompete pathogens for adhesion sites and nutrients, directly reducing populations of Citrobacter freundii and other Enterobacteriaceae
Glutathione scavenges reactive oxygen species generated by activated neutrophils, reducing oxidative damage to epithelial cells and preventing apoptosis
Vitamin D3 upregulates tight junction proteins and induces antimicrobial peptide production, while zinc stabilizes epithelial cytoskeleton and prevents barrier disruption
Reduced bacterial endotoxin load and oxidative stress decrease activation of innate immune cells in the lamina propria, lowering pro-inflammatory cytokine production
Resolution of mucosal inflammation promotes epithelial restitution, restores mucus layer integrity, and eliminates niches that support pathogenic bacterial colonization
