A colleague just Tweeted me this Centers for Disease Control and Prevention map, which, over the course of 30 seconds, shows you exactly how fat America has become since 1985.

Click on the link and watch for yourself.

So how bad is it?

Colorado, where presumably everyone still hikes and eats granola, is the only state in the Union where obesity rates are under 20 percent of the population. Three states — Mississippi, Tennessee, and Alabama, all Southern states, which tells you something — have obesity rates at or above 30 percent of the population.

Pretty scary stuff. It's scary enough to make Y&H turn to a Snickers bar for comfort.

Reports CNN:

The CDC has not identified what food or foods might be causing this outbreak. It is also not yet releasing a list states involved in the investigation, which they say is ongoing.

CDC officials and state public health workers are conducting case control studies, which means they're tracking down people who have been infected as early as September to determine what they may have consumed, to find a common cause.

The Food and Drug Administration and the U.S. Department of Agriculture are in contact with the CDC, but without a determination of the cause of the outbreak, their involvement is limited.
