The first experiment looked into just how quickly and effectively a high-fiber diet can start working. Don and Wolfgang, two European long-distance truckers, say their diets consist of whatever they can eat in their truck cab—which has almost no fiber.

Getting enough fiber is not just about eliminating the discomfort of constipation. Without enough fiber, there is an increased risk of bowel or colon cancer.

The first step was to measure just how slowly their guts were moving. Both swallowed a pill that contains a tiny transmitter so researchers can track how long it takes for them to process food. With hardly any fiber, it took nearly a full day for Don to pass his pill—and more than 42 hours for Wolfgang.

Then Don and Wolfgang went on a weeklong change, loading up on whole grain cereal bars, whole wheat bread and fruit with the skin on it.

Will they find this to be a moving experience?
