Every day, millions of Americans prick their fingertips, feed blood into a glucose meter, and adjust their diet in a ritual to stay healthy. This is the diabetic way of life, what many older diabetics call having the "sweet blood." And it has become an American way of life, affecting about one in ten people with rates among minorities and the poor in double-digit percentages. The complications are serious and deadly—neuropathy, blindness, cardiovascular disease, and renal failure—with total costs around $245 billion for 2014 alone. Dr. Frank Vinicor, former American Diabetes Association president, has called diabetes "the Rodney Dangerfield of diseases": expensive to treat, hard to manage, and easy to ridicule.
