On this edition of Your Call, we continue our series on chronic disease and cancer with gastroenterologist Dr. Alan Desmond.

He asks: when food is fast becoming the leading cause of poor health, disability, chronic gut health problems, and healthy years lost, why are we doctors not talking about it all the time? A major problem is that most people are not eating enough fiber.

Research shows that a fiber-rich diet can lower the risk of chronic disease, cancer, and early death, but only five percent of people in the US eat the recommended amount of fiber each day. Dr. Desmond says all health begins in the gut. How can we improve our fiber intake and overall health?
