There was a documentary filmed called "Raw for 30 Days" which followed a group of diabetics going on a raw food program and a month later they were insulin free, many of them still no longer diabetic, off insulin, even a year later.
I don't know if the documentary is available yet, but elements of this is on the DVD "Raw For Life".
Besides addressing issues of diabetes and general health, there is a lot of solid information about transitioning to a raw food lifestyle, recipes, and more, with interviews with people like Tony Robbins, David Wolfe, Gabriel Cousens, even the guy from the movie Super Size Me. It is a fascinating DVD.
