To Dr. David Katz, there's not much mystery behind the cause of major diseases that, as he puts it, "are taking years from life and life from years." It's our lifestyle.
"DNA is not destiny," he wrote last year in the Huffington Post. "To a much greater extent, choices under our control determine our fate. We have scientific evidence to show that if we change our own behavior, we change the behavior of our genes. We can nurture nature."
Katz is one of several leading doctors and health-care experts in Rochester, Minn., this week to speak at the Mayo Clinic's Transform 2014 Symposium. He'll speak with Tom Weber about what we know — and don't know — about nutrition, exercise and how to stay well.
