Let Them Eat Dirt

Allergies, obesity, asthma, diabetes, auto-immune and intestinal disorders are all on the rise, with the incidence of some diseases doubling every ten years. New research points to changes in the ecosystem of microbes that live on and inside every one of us -- our microbiomes -- as a major cause. But how could one's gut microbes increase the odds of developing conditions as radically different as asthma and diabetes? Hosted by Good Morning America's Becky Worley, and based on the book of the same name by B. Brett Finlay, PhD and Marie-Claire Arrieta, PhD, LET THEM EAT DIRT features families, doctors, and researchers who are sleuthing out what's harming our microbes -- and what we can do to reverse this dangerous trend.
