From your source: “From 2006 to 2011, the number of new cases of diagnosed diabetes has shown no significant change.” Just goes to show that statistics can/are highly manipulated to get the desired result. Also, U.S. population is up over 20% 1995-2014 (so naturally more diabetes cases). http://www.cdc.gov/diabetes/statistics/incidence/fig1.htm
