When it comes to diabetes, just about everyone has heard there's an epidemic upon us.
In 2010, about 18.8 million people of all ages in the U.S. had been diagnosed with diabetes, according to the Centers for Disease Control and Prevention. Another 7 million had diabetes but hadn't been diagnosed.
How much have things changed?
Back in 1995, about 4.5 percent of adults in the U.S. had been diagnosed with diabetes. By 2010, the prevalence had zoomed to 8.2 percent.
