This "Surviving & Thriving" segment is presented by Florida Hospital. With the right kind of care and support and the right attitude, it's possible to not only survive life's greatest challenges but to thrive in the aftermath.

When you hear Dr. Terry Wahls' story, you may start to wonder if we all have more control over our health than we think. What happened to her is nothing short of stunning, and she has a message she's determined to pay forward.

About 15 years ago, Dr. Wahls was diagnosed with multiple sclerosis, a devastating disease that took hold of this mountain climber and marathoner and left her bedridden. Nine months later, though, she recovered. How? It seemed like a miracle. She says it wasn't a miracle; it was a direct result of her diet.

She describes this transformation in her new book, "The Wahls Protocol: How I Best Progressive MS Using Paleo Principles and Functional Medicine."

Dr. Wahls, a clinical professor of medicine at the University of Iowa Carver College of Medicine, joins us to discuss the specifics of her comeback and why she says she isn't just offering false hope to the more than 2 million people suffering from MS.

She shares how she arrived at her discoveries and reveals some of the clinical trials she's conducted to back up her claims. Find out the superfoods she believes we should be eating. Here's a hint: they're not even close to the superfoods you've been hearing about for years.

Dr. Wahls also explains the other diseases this functional medicine can combat, including diabetes 2, irritable bowel syndrome and more.
