It's interesting to see the seemingly strong correlation between the highest obesity rates and the highest diabetes rates. I would have guessed, sure, but this looks like fairly strong evidence there's a correlation
Obesity is the main risk factor for adult-onset diabetes; diabetes and high blood pressure are the main risk factors for chronic kidney disease, and when your kidneys finally fail (whether it's under the strain of sweet tea and biscuits & gravy, or Pepsi and Big Macs), you need dialysis.
It's getting so bad now that we're seeing adult-onset diabetes, the diet-inflicted kind, appearing in kids -- not to be confused with juvenile-onset diabetes, the kind that's normally genetic.
