So somthing I wondered this growing rate of diabetes that we hear alot about are there actually any valid stats on wether more people do actually have diabetes now than used to? Like a % adults diagnosed with diabetes over the last 50 years? Or is it an impossible figure as more are getting diagnosed now that maybe did not before?
