High blood sugar a Top-5 global killer

When it comes to the world's top killers (not people, but causes), what comes to your mind? Heart attacks? Cancer? Those are in there along with high blood sugar -- which was a surprise to me.

Why? Because high blood sugar is an indicator of future diabetes problems, which definitely can lead to an early death -- and in many cases, does.

A new study out of Harvard University estimated that globally, over 3.1 million deaths are caused each year in over 52 nations just due to high blood sugar. One of he study's top researchers said that "Our results show that one in five deaths from heart disease and one in eight from stroke worldwide are attributable to higher-than-optimum blood sugar."
