This according to NPR. So now we know the reason Americans started getting obese at the same time the government started telling us what to eat. The result? Today, almost one-third of all American adults are obese and the rate is increasing. And this year, for the first time, a majority of American adults are either diabetic or pre-diabetic.
But remember when you are told that you are killing the planet: global warming research has nothing to do with money! It's hard science and scientists would never let their research and publishing be influenced by grants, awards, and seats at international conferences!
Update: The science is settled!
