Notwithstanding the golden "correlation != causation" adage, I found that only two things are truly consumed in much larger quantities in America than any other country I know: soda and high fructose corn syrup...at the same time being the only country with a 35% obesity rate...hmmmm
Not true. Saudi Arabia is the most obese country on earth, at 70%.
Britain, Australia, and New Zealand are also substantially obese. All of those are coming increasingly close to catching America in obesity, with their obesity levels exploding higher.
