What kind of silly question is this ?
Have you been to Mexico ?
There are many, many people who live in severe poverty in Mexico.
Many times the people construct makeshift homes from plywood, cheap sheets of metal/steal and cardboard (sometimes along the road, on property that is not their own).
They barely have enough to eat to stay alive, yet alone eat to become "obese."
Yes there is poverty in every nation, but in Mexico it is everywhere.
This. I lived in Indiana for 2 years and, in my opinion, American food is not terribly unhealthy in comparison with other countries. The point is some people in the US tend to eat A LOT.
