For generations, the intuition that the body's interior life shapes the mind has lingered at the edge of science — plausible but unproven in the human case. Now, for the first time, researchers have documented in living people a direct relationship between the bacteria inhabiting the digestive tract and the production of neurotransmitters that govern mood, stress, and neurological function. The gut-brain axis, long theorized through animal experiments, has at last found its human evidence. What was once a promising hypothesis has become a measurable biological fact, opening a new chapter in ho
