True there are unhealthy options on both sides of the border, (and all over the world) but America is one fat ass country...
One quick Google search gave me this as the first link, other sites may rank it slightly differently
http://www.nationmaster.com/graph/he...health-obesity
Ranked 1st at 30.6% of it's population as obese... USA.
Canada is actually ranked 11th at 14.3, or a little less than half the rate of the States.
So, really, commenting about the fat asses in America is really just calling a spade a spade. You can be as indignant as you want to be about it, but they really are doing SOMETHING (or many things) wrong down there. It's probably not as simple as a burger chain, but they are pretty fricken fat.
Mexico, UK, Slovakia, and Greece round out the top 5. The only one up there that surprises me is Slovakia. Also I did think Canada was ranked higher.
