I think the food in the U.S is highly contaminated. The poor tend to be very obiese, but the majority of americans are obiese. Almost all of the meat and dairy is loaded with hormones, antibiodics, and chemicals. Almost all of the bread products (or any other food for that matter) is loaded with tons of chemicals. Just look at the ingredients on anly loaf of bread. It's insane. It is very difficult to feed a family enirely organic food when you have a modest income.
Anyway, enough of my ranting.
