Miracle Dan is in fact Silent Dan - for now. Would love to hear an interview with him. If vitamin D could cure T1D, then all you'd have to do is spend a summer outside and voilá. However, vit D deficiency can cause T1D in some, especially the finnish population (children) have been studied.
If this is indeed true, then I don't buy into "not doing anything at all". I don't believe that megadosing vitamins could cure anybody, but I believe that using that with a combination of EVERYTHING (diet, exercise, vitamins, dealing with childhood traumas etc.) may have very positive effects on certain individuals, even remission. So what's Dan's secret?
