A new report predicts a third of U.S. adults could
be diabetic by 2050.

The Centers for Disease Control and Prevention predicted today that by 2050 one of three people in the U.S. could have diabetes, up from one in 10 today. That’s the bad news.

The good news? That’s the prediction "if current trends continue." Admittedly, countering those trends—including the ever-growing number of us who are ever-growing couch potatoes—isn’t easy. But given that the disease multiplies the risk of heart attack, stroke, blindness, and disability, and more than doubles an individual’s health-care costs, it’s certainly worth trying.

And, as our reports have shown, it is possible to prevent type 2 diabetes or, if you already have it, effectively treat it. Read about our Best Buy Drugs for diabetes and our Ratings of blood-glucose monitors (available to subscribers).
