Trillions of microbes live in your gut, and "gut health" is everywhere — but what's actually real? This short course separates the science from the hype: who lives in your gut, the jobs they genuinely do for you, what the evidence says about feeding them (fiber, prebiotics, probiotics), what the gut–brain axis really is, and what happens when the balance tips. Educational, evidence-graded, and clear about what we don't yet know.
