And what we've discovered at least in mice, and also to some extent, we and others have discovered this to occur in humans, is that the dominant factor that determines the diurnal activity of microbes throughout the course of a day is the timing of our feeding. And when we disrupt the timing of our feeding, for example, by subjecting mice to a shift to our kind of lifestyle or jet lag or even in genetically clock-deficient mice, we disrupt the microbial circadian activity.
