This study uses metatranscriptomic data to analyze how dietary composition affects gut microbiota function, finding that a fiber-rich diet promotes beneficial metabolic pathways while a low-fiber diet increases harmful protein and mucin degradation.

This study investigates the relationship between methanogens and human metabolizable energy, finding that high CH4 producers have greater serum propionate and host ME, and a network link between methanogens and fiber-degrading bacteria.
