Long-Term Intake of Pork Meat Proteins Altered the Composition of Gut Microbiota and Host-Derived Proteins in the Gut Contents of Mice.

Pork meat protein diets alter the gut microbiota composition and specific gut microbes may have a great impact on protein digestion and absorption by regulating the secretion of digestive proteins from the host. These findings provide a new insight into the associations of long-term intake of meat protein diet with gut microbiota and host.
