Turns out your gut isn’t just for digesting tacos—it’s running half your body’s operations like a microscopic mafia. In this episode of AI Investigates, we dive deep (and we mean deep) into the world of gut microbes, those trillions of tiny freeloaders living rent-free in your intestines. They regulate your immune system, influence your mood, and might even decide whether kale helps or hurts you. We also talk poop transplants—yes, that's a thing—and why your microbiome throws a tantrum every time you eat nothing but beige food. It's health, science, and a whole lot of fiber. Bring snacks (preferably fermented).
