• Fiber acts as a prebiotic, serving as food for beneficial bacteria in the large intestine. — 10 Benefits of Fiber
• The human gut contains approximately 39–40 trillion bacteria, making it more accurately modeled as a complex ecosystem than a discrete individual organism. — Food as Medicine for the Brain: Gut, Microbiome, and Mental Health
• Lactobacillus and related species ferment fiber as their primary energy source in the colon. — 10 Benefits of Fiber
• Fiber supports an acidic pH in the colon by feeding acid-producing bacteria, which suppresses pathogens. — 10 Benefits of Fiber
• Streptococcal infection is the strongest known environmental trigger for psoriasis onset and flares. — Psoriasis as a Gut-Driven Systemic Disease: Root Causes, Immune Pathways, and Naturopathic Treatment
• Fiber's prebiotic action can worsen bacterial overgrowth in the small intestine in people with SIBO. — 10 Benefits of Fiber
• Gut dysbiosis amplifies the chronic low-grade inflammation that characterizes PCOS. — PCOS as Metabolic Syndrome: Diagnosis, Pathophysiology, and Treatment
• Beta-glucuronidase activity in the gut cleaves estrogen metabolites and releases free estrogen back into circulation, contributing to estrogen dominance. — PCOS as Metabolic Syndrome: Diagnosis, Pathophysiology, and Treatment
• The gastrointestinal microbiome contributes to NO homeostasis through nitrate reduction, folate synthesis, biopterin synthesis, and mucosal integrity maintenance. — Nitric Oxide, Methylation, and the Microbiome: A Clinical Integration Framework
• Hypochlorhydria, H. pylori infection, PPI/antacid use, and gut dysbiosis all impair nitrate reduction capacity. — Nitric Oxide, Methylation, and the Microbiome: A Clinical Integration Framework
