I think there is more going on here than food intake and activity levels. I think, in the near future, it will be revealed that some component or components in either the food chain, or medicine chain, are causing this. Its too large and widespread a problem to simply be down to food intake and activity levels. I suspect that the cause is well know, but not revealed yet, like the link with lung cancer and smoking were. Or heart disease and transfats were.
something is poisoning our livers and pancreases in a mass epidemic. Blaming individuals doesnt address the cause, and deflects the blame, suppressing and diverting the focus on revealing the true cause.
My money is on it being linked to pollution and organo-phosphates and artificial fertilizers, or maybe on something leaching out of the plastics we use to wrap and, often, cook foods.
I know this is the Daily Mail, but i cant find the link to the original study - note the date of the article:
