For generations, nuts were cast as dietary villains, their fats feared and avoided. Now, epidemiologist Tim Spector points to them as quiet allies in one of the body's most consequential relationships—the dialogue between gut and brain. The lesson is not merely about almonds or walnuts, but about how science, when it listens carefully, learns to trade certainty for complexity, and how the health of the mind may begin, improbably, in the intestine.
