Americans are buying more organic food than ever, whether it’s apples from Washington or avocados from Mexico. But when that label says “organic,” especially on something grown thousands of miles away, how do you know it’s truly organic? We get to the bottom of that on this week’s Paging Dr. Gupta. Plus, grounding sheets claim to help with sleep and pain...but does the science back that up? This episode was produced by Jennifer Lai with assistance from Leying Tang.

Author Jonathan Gluck says most cancer stories take one of two forms:  “He or she fought valiantly and died, or he or she fought valiantly and survived.” But Gluck, who was told in the prime of life that he had an incurable type of blood cancer, has a different kind of story.  Dr. Sanjay Gupta sits down with Gluck to discuss his new book, “An Exercise in Uncertainty: A Memoir of Illness and Hope,” and what two decades of living with cancer have taught him – and might teach us – about living well.
