Diet and diabetes: lessons from the ruby red slippers

The 1939 film The Wizard of Oz provides an interesting metaphor for a discussion on type 2 diabetes. In the story, Dorothy, a young girl, is knocked unconscious during a tornado. She and her dog Toto are swept up in the storm and dropped into the Land of Oz, where she is told that to get back home, she must follow the Yellow Brick Road and seek out the magical wizard. Along the way, she meets the Scarecrow, the Tin Man and the Cowardly Lion, who join her, hoping to receive what they lack themselves (a brain, a heart, and courage, respectively). Together, they seek out the wizard, only to learn that he has no answers. Ultimately, they are rescued when Glinda the Good Witch of the North points out that all along they had possessed exactly what was needed for happiness. It seems that those dedicated to eradicating type 2 diabetes are on a similar journey. Caroline Trapp explains why.
