Your intestines are basically a microscopic Game of Thrones. We talk a lot about gut bacteria, but the real power players are bacteriophages—viruses that specifically hunt and kill those bacteria. By constantly pruning bacterial populations, these viruses dynamically alter how you absorb nutrients and process fats. It turns out your digestion is governed by an invisible, ongoing viral war, making the concept of a static 'gut microbiome' completely scientifically obsolete.
