Your Body Knows Its Allies at Gut Level
January 24, 2007
How come your body doesn’t fight its good bacteria?  It sounds like a question only a scientist or a kid would ask, but think about it.  Your body jumps to arms to fight off pathogens, but lets millions of bacteria live in the intestines.  These bacteria help you digest your food, but are not “you.”  […]
