Gut microbiota-derived lipopolysaccharides (LPS) and peptidoglycan (PGN) promote NAFLD progression by activating hepatic Toll-like receptors (TLR4, TLR2, NOD1/2), triggering inflammatory cytokine release and steatosis.

Your liver health is heavily influenced by what lives in your gut. An unhealthy diet can disrupt gut bacteria, allowing harmful bacterial parts (like LPS) to leak into your bloodstream and inflame your liver. Prioritizing a diet that supports a healthy gut microbiome (e.g., high fiber) may help reduce this inflammatory load on the liver.

The over-activated immune cells induced by the products generated from bacteria may result in more severe liver damage, inflammation, and fibrosis, thus accelerating the development of NAFLD.
