Distinction of meal quality and interaction with the gut microbiota by breath volatilome analysis in humans

Gut Microbes
Diet strongly influences the composition and metabolic activity of the gut microbiota, which in turn impacts host physiology and health. The metabolites produced by gut microbes include volatile compounds detectable in exhaled breath, which offers a ...
