Scientists from The University of Texas at Austin and five other institutions have discovered that the more diverse the diet of a fish, the less diverse are the microbes living in its gut. If the effect is confirmed in humans, it could mean that the combinations of foods people eat can influence the diversity of their gut microbes.
