What if the most surprising thing about your dinner isn’t what’s on your plate—but when you eat it?

In this episode, Dr. Dawn Lemanne and Dr. Deborah Gordon investigate the unsettling rise of colorectal cancer in younger adults—and explore clues that reach far beyond family history.

Three revelations drive the conversation: a possible connection between mealtimes and the colon’s repair rhythms; an animal experiment in which a chemical’s effects hinge on an unexpected accomplice; and an exercise target that makes the usual advice sound surprisingly modest.

Could an ordinary evening routine interfere with your gut’s overnight maintenance? What changes when the same chemical encounters a different microbial environment? And how much movement are we really talking about?

Along the way, the doctors examine additives hiding in “healthy” foods, explain why some precancerous growths are harder to spot, and distinguish promising hypotheses from practical priorities.

The conversation keeps returning to one question: which everyday choices deserve your attention—and which assumptions deserve a second look?
