Discuss the specific functions of microorganisms in the gut
Microorganisms:
? consume and break down fiber and other undigested food residues
? excrete fatty acids as an end product of fiber digestion; the fatty acids are absorbed and serve as a source of energy
? help fight infection by signaling the presence of harmful microbes which are then targeted by the body's infection-fighting immune system
? produce, and thereby contribute to, the body's supply of biotin, vitamin B12, and vitamin K
