It seems to always be acceptable to blame the US for any problem but as pointed out in the article neither sugar cane, refined sugar nor high-fructose corn syrup originated in the US. And almost every "US style food" originated somewhere else. So should we blame Italy, France, China and Mexico too?

I would say the US may be primarily responsible for the technology (agricultural, supply chain, financing, etc) that made food potentially affordable to everyone. An unfortunate consequence of having enough food to eat is being able to eat too much.
